Insecure Password Recovery Questions

Vulnerability Assessment as a Service (VAaaS)

Tests systems and applications for vulnerabilities to address weaknesses.

IPRQs (Insecure Password Recovery Questions) are a security measure used by some websites and services to help users recover access to their accounts if they forget their password. Instead of sending a password reset link or temporary password, the user is asked to answer one or more personal questions, such as “What is your mother’s maiden name?” or “What was the name of your first pet?” The answers to these questions are typically personal information that is not publicly available, but can be guessed or obtained through social engineering tactics, making IPRQs an insecure method of password recovery.

Example of vulnerable code on different programming languages:


in PHP:

				
					$mother = $_POST['mother'];
$pet = $_POST['pet'];

$query = "SELECT * FROM users WHERE mother='$mother' AND pet='$pet'";
$result = mysqli_query($connection, $query);

if (mysqli_num_rows($result) > 0) {
   // Allow password reset
} else {
   // Display error message
}

				
			


This PHP code is vulnerable to SQL injection attacks. The code collects the user’s answers to the password recovery questions from an HTML form and inserts them directly into an SQL query string without any sanitization or validation. An attacker can exploit this vulnerability by crafting a malicious input that includes SQL commands that can modify or leak the database contents. For example, an attacker could enter the following as an answer to one of the questions:

				
					' OR 1=1;--

				
			


This input would cause the SQL query to become:

				
					SELECT * FROM users WHERE mother='' OR 1=1;--' AND pet='';

				
			


The SQL comment -- causes the rest of the query to be ignored, effectively bypassing the password recovery check and allowing the attacker to reset the password.

To fix this vulnerability, the code should use prepared statements and parameterized queries, which separate the query logic from the user input and prevent SQL injection attacks.

• in Python:

				
					mother = input("What is your mother's maiden name? ")
pet = input("What was the name of your first pet? ")

query = f"SELECT * FROM users WHERE mother='{mother}' AND pet='{pet}'"
result = db.execute(query)

if result.rowcount > 0:
   # Allow password reset
else:
   # Display error message

				
			

 

This Python code is also vulnerable to SQL injection attacks. The code prompts the user to enter their answers to the password recovery questions via the input() function and constructs an SQL query string using formatted string literals (f-strings). Like in the PHP example, an attacker can craft malicious input that contains SQL commands and inject them into the query string, leading to unintended behavior.

To fix this vulnerability, the code should use parameterized queries with placeholders and bind the user input to the query using database-specific APIs like the psycopg2 library for PostgreSQL or the mysql-connector-python library for MySQL.

• in Java:

				
					String mother = request.getParameter("mother");
String pet = request.getParameter("pet");

String query = "SELECT * FROM users WHERE mother='" + mother + "' AND pet='" + pet + "'";
ResultSet result = statement.executeQuery(query);

if (result.next()) {
   // Allow password reset
} else {
   // Display error message
}

				
			

 

This Java code is vulnerable to SQL injection attacks as well. The code retrieves the user’s answers to the password recovery questions from an HTTP POST request and constructs an SQL query string using string concatenation. As in the previous examples, an attacker can exploit this vulnerability by injecting SQL commands into the query string using malicious input.

To fix this vulnerability, the code should use parameterized queries and bind the user input to the query using placeholders and prepared statements, just like in the PHP example. Additionally, the code should use a connection pool or a connection factory to manage database connections and avoid connection leaks or connection pooling attacks.

Examples of exploitation Insecure Password Recovery Questions

Guessing:

If an attacker knows some basic information about the target user, such as their full name, date of birth, or address, they can guess the answers to the password recovery questions. For example, if the question is “What is your favorite color?”, an attacker might try common colors such as “blue”, “red”, or “green” and guess the correct answer. This type of attack is called a brute-force or dictionary attack.

Social engineering:

An attacker can try to trick the target user into revealing the answers to the password recovery questions by pretending to be a trusted entity, such as a customer service representative or a friend. For example, the attacker might call the target user and claim to be a customer service representative from the target user’s bank, and ask them to confirm their account information, including the answers to the password recovery questions.

Research:

An attacker can research the target user’s personal information from public sources, such as social media profiles, public records, or data breaches, to obtain the answers to the password recovery questions. For example, if the question is “What is your mother’s maiden name?”, the attacker might search for the target user’s family members on social media and find their mother’s maiden name.

Exploiting vulnerabilities:

As demonstrated in the vulnerable code examples, an attacker can exploit vulnerabilities in the password recovery system to bypass the security checks and gain unauthorized access to the target user’s account. For example, an attacker might use SQL injection attacks to inject malicious input into the password recovery form and manipulate the SQL queries to reset the password.

Privilege escalation techniques for Insecure Password Recovery Questions

Answer manipulation: 

An attacker can manipulate the answers to the password recovery questions to bypass the security checks and reset the password. For example, if the question is “What is your mother’s maiden name?”, the attacker might try entering a different name that they know the target user has used in the past, or try entering a common surname that could belong to the target user’s mother.

Session hijacking: 

If the password recovery process does not include proper session management or authentication controls, an attacker might be able to hijack the target user’s session and bypass the password recovery checks. For example, if the target user is logged into their account and initiates the password recovery process, an attacker might be able to intercept the HTTP request and modify the answers to the questions to gain access to the account.

Reverse engineering: 

An attacker might reverse engineer the password recovery system to understand how it works and identify vulnerabilities that can be exploited. For example, an attacker might analyze the network traffic between the client and server, or decompile the source code of the web application to understand how the password recovery process is implemented.

Exploiting code vulnerabilities: 

As demonstrated in the vulnerable code examples, an attacker can exploit code vulnerabilities such as SQL injection or command injection to bypass the password recovery checks and gain access to the target user’s account. The attacker might modify the SQL queries or command parameters to manipulate the password recovery process and reset the password.

General methodology and checklist for Insecure Password Recovery Questions

Methodology:

  1. Identify the password recovery process: Determine how the password recovery process works for the application or system being tested. This might involve reviewing documentation or user guides, examining the source code, or using tools such as web proxies or intercepting proxies to capture network traffic.

  2. Identify the security controls: Review the security controls that are in place to prevent unauthorized access to the password recovery process. This might include authentication controls, input validation, session management, and rate limiting.

  3. Identify the password recovery questions: Determine what questions are used in the password recovery process and how they are presented to the user. This might involve reviewing the user interface, examining the source code, or using tools such as web proxies or intercepting proxies to capture network traffic.

  4. Test for guessable questions: Try to guess the answers to the password recovery questions using common information that might be known about the target user, such as their name, date of birth, or city of birth. If it is possible to guess the answers, this indicates that the questions are insecure.

  5. Test for answer manipulation: Try to manipulate the answers to the password recovery questions to bypass the security controls and gain unauthorized access to the account. This might involve modifying HTTP requests, injecting SQL or other commands, or exploiting other vulnerabilities in the application.

  6. Test for session hijacking: Attempt to hijack the target user’s session during the password recovery process to bypass the security controls and gain unauthorized access to the account. This might involve using tools such as session hijacking proxies or intercepting proxies to capture and modify network traffic.

  7. Document and report findings: Document all findings and report them to the appropriate parties. Include details such as the specific vulnerabilities identified, the potential impact of each vulnerability, and recommendations for remediation. Additionally, provide guidance on how to improve the overall security of the password recovery process.

The Common Weakness Enumeration (CWE)

• CWE-640: Weak Password Recovery Mechanism for Forgotten Password – This vulnerability occurs when a password recovery mechanism is weak and can be easily bypassed, allowing an attacker to gain unauthorized access to an account. Weak password recovery mechanisms include things like using easily guessable questions or answers, or using weak or no authentication to verify a user’s identity during the recovery process.

• CWE-655: Insufficient Complexity of Password Recovery Questions – This vulnerability arises from password recovery questions that have insufficient complexity. If these questions are poorly designed, they can be guessed or easily obtained by attackers, allowing them to bypass the primary authentication method and gain unauthorized access.

• CWE-656: Reliance on Security Through Obscurity in Password Recovery – This vulnerability occurs when password recovery relies on the secrecy of a particular algorithm or method, rather than implementing proper security measures. Attackers can discover these methods and use them to bypass authentication.

• CWE-661: Weak Security Question Answer Generation – This vulnerability occurs when security questions are generated with predictable or easily guessable answers. Attackers can use these answers to bypass authentication.

• CWE-662: Weak Security Answer Validation – This vulnerability occurs when the answers to security questions are not validated properly, allowing attackers to bypass authentication by submitting incorrect or incomplete answers.

• CWE-663: Insufficient Password Recovery Time Frame – This vulnerability occurs when the time frame for password recovery is too long, allowing attackers to continue guessing or brute-forcing password recovery questions until they succeed.

• CWE-664: Insufficient Password Recovery Authentication – This vulnerability occurs when the authentication mechanisms used during password recovery are weak or non-existent, allowing attackers to gain unauthorized access to an account.

• CWE-665: Improper Initialization in Password Recovery – This vulnerability occurs when password recovery mechanisms are not initialized properly, allowing attackers to bypass authentication.

• CWE-666: Operation on Password Hash with Insufficiently Random Salt – This vulnerability occurs when passwords are hashed with insufficiently random salt, making it easier for attackers to perform brute-force attacks to crack passwords.

• CWE-669: Incorrect Resource Transfer Between Sphere of Control – This vulnerability occurs when resources are transferred between different security domains without proper authorization or validation, allowing attackers to gain unauthorized access to these resources.

Top 10 CVES related to Insecure Password Recovery Questions

• CVE-2020-15850 – Insecure permissions in Nakivo Backup & Replication Director version 9.4.0.r43656 on Linux allow local users to access the Nakivo Director web interface and gain root privileges. This occurs because the database containing the users of the web application and the password-recovery secret value is readable.

• CVE-2019-0035 – When “set system ports console insecure” is enabled, root login is disallowed for Junos OS as expected. However, the root password can be changed using “set system root-authentication plain-text-password” on systems booted from an OAM (Operations, Administration, and Maintenance) volume, leading to a possible administrative bypass with physical access to the console. OAM volumes (e.g. flash drives) are typically instantiated as /dev/gpt/oam, or /oam for short. Password recovery, changing the root password from a console, should not have been allowed from an insecure console. Affected releases are Juniper Networks Junos OS: 15.1 versions prior to 15.1F6-S12, 15.1R7-S3; 15.1X49 versions prior to 15.1X49-D160; 15.1X53 versions prior to 15.1X53-D236, 15.1X53-D496, 15.1X53-D68; 16.1 versions prior to 16.1R3-S10, 16.1R6-S6, 16.1R7-S3; 16.1X65 versions prior to 16.1X65-D49; 16.2 versions prior to 16.2R2-S8; 17.1 versions prior to 17.1R2-S10, 17.1R3; 17.2 versions prior to 17.2R1-S8, 17.2R3-S1; 17.3 versions prior to 17.3R3-S3; 17.4 versions prior to 17.4R1-S6, 17.4R2-S2; 18.1 versions prior to 18.1R2-S4, 18.1R3-S3; 18.2 versions prior to 18.2R2; 18.2X75 versions prior to 18.2X75-D40; 18.3 versions prior to 18.3R1-S2. This issue does not affect Junos OS releases prior to 15.1.

• CVE-2017-5521 – An issue was discovered on NETGEAR R8500, R8300, R7000, R6400, R7300, R7100LG, R6300v2, WNDR3400v3, WNR3500Lv2, R6250, R6700, R6900, and R8000 devices. They are prone to password disclosure via simple crafted requests to the web management server. The bug is exploitable remotely if the remote management option is set, and can also be exploited given access to the router over LAN or WLAN. When trying to access the web panel, a user is asked to authenticate; if the authentication is canceled and password recovery is not enabled, the user is redirected to a page that exposes a password recovery token. If a user supplies the correct token to the page /passwordrecovered.cgi?id=TOKEN (and password recovery is not enabled), they will receive the admin password for the router. If password recovery is set the exploit will fail, as it will ask the user for the recovery questions that were previously set when enabling that feature. This is persistent (even after disabling the recovery option, the exploit will fail) because the router will ask for the security questions.

• CVE-2016-10176 – The NETGEAR WNR2000v5 router allows an administrator to perform sensitive actions by invoking the apply.cgi URL on the web server of the device. This special URL is handled by the embedded web server (uhttpd) and processed accordingly. The web server also contains another URL, apply_noauth.cgi, that allows an unauthenticated user to perform sensitive actions on the device. This functionality can be exploited to change the router settings (such as the answers to the password-recovery questions) and achieve remote code execution.

• CVE-2016-10175 – The NETGEAR WNR2000v5 router leaks its serial number when performing a request to the /BRS_netgear_success.html URI. This serial number allows a user to obtain the administrator username and password, when used in combination with the CVE-2016-10176 vulnerability that allows resetting the answers to the password-recovery questions.

• CVE-2007-2361 – Symantec Norton Ghost, Norton Save & Recovery, LiveState Recovery, and BackupExec System Recovery before 20070426, when remote backups of restore points images are configured, uses weak permissions (world readable) for a configuration file with network share credentials, which allows local users to obtain the credentials by reading the file.

• CVE-2007-2360 – Symantec Norton Ghost, Norton Save & Recovery, LiveState Recovery, and BackupExec System Recovery before 20070426, when remote backups of restore point images are configured, encrypt network share credentials with a key formed by a hash of the username, which allows local users to obtain the credentials by calculating the key.

• CVE-2006-0363 – The “Remember my Password” feature in MSN Messenger 7.5 stores passwords in an encrypted format under the HKEY_CURRENT_USER\Software\Microsoft\IdentityCRL\Creds registry key, which might allow local users to obtain the original passwords via a program that calls CryptUnprotectData, as demonstrated by the “MSN Password Recovery.exe” program. NOTE: it could be argued that local-only password recovery is inherently insecure because the decryption methods and keys must be stored somewhere on the local system, and are thus inherently accessible with varying degrees of effort. Perhaps this issue should not be included in CVE.

How to be protected from Insecure Password Recovery Questions

  1. Use strong passwords – Use strong passwords that are difficult to guess or brute force. Avoid using passwords that can be easily guessed, such as common words or phrases, personal information like your name or birthdate, or sequential numbers.

  2. Enable two-factor authentication – Two-factor authentication adds an extra layer of security to your account, making it more difficult for attackers to gain access even if they manage to obtain your password.

  3. Use security questions wisely – If you have to set up security questions for your account, choose questions and answers that are difficult to guess or find through social media or other online sources.

  4. Be aware of phishing scams – Be cautious of emails or messages that ask you to click on links or provide sensitive information, especially if they appear to come from a trusted source.

  5. Keep your software up to date – Keep your operating system, web browser, and other software up to date with the latest security patches and updates to reduce the risk of vulnerabilities being exploited.

  6. Use a password manager – Consider using a password manager to generate and store complex passwords for your accounts. This can help you avoid using the same weak password across multiple accounts, and reduce the risk of password reuse attacks.

  7. Be wary of public Wi-Fi networks – Avoid using public Wi-Fi networks, or use a virtual private network (VPN) to encrypt your traffic and protect your data from interception.

Mitigations for Insecure Password Recovery Questions

  1. Eliminate security questions – If possible, eliminate the use of security questions altogether, or replace them with more secure authentication methods such as two-factor authentication.

  2. Use complex security questions – If security questions are necessary, use complex questions that are difficult to guess or find online. Avoid questions that are related to personal information, and provide users with a list of pre-defined questions to choose from.

  3. Limit the number of attempts – Limit the number of attempts that users can make to answer security questions, and enforce a time delay between attempts to prevent automated attacks.

  4. Monitor account activity – Monitor account activity for unusual behavior, such as repeated failed attempts to answer security questions, and implement measures to block suspicious activity.

  5. Educate users – Educate users on the risks associated with insecure password recovery questions, and provide them with best practices for creating and storing strong passwords.

  6. Implement rate limiting – Implement rate limiting on password recovery requests to prevent attackers from repeatedly guessing answers to security questions.

  7. Enforce strong password policies – Enforce strong password policies, such as minimum length and complexity requirements, to prevent attackers from easily guessing passwords or brute-forcing them.

Conclusion

Insecure password recovery questions are a significant security concern that can lead to the compromise of user accounts and sensitive data. Attackers can exploit weak security questions or answers, or use social engineering tactics to obtain the answers and gain unauthorized access to accounts.

To prevent insecure password recovery questions, organizations should eliminate or limit the use of security questions, use complex and unpredictable questions, and implement rate limiting and account monitoring. It is also important to educate users on the risks associated with insecure password recovery questions and enforce strong password policies.

Developers should also follow secure coding practices, such as validating user input, using secure storage mechanisms for passwords and security question answers, and avoiding security through obscurity.

Overall, preventing insecure password recovery questions requires a multi-faceted approach that involves technical controls, user education, and a strong security culture.
