Insufficient Cryptographic Protection of Data in Transit

Vulnerability Assessment as a Service (VAaaS)

Tests systems and applications for vulnerabilities to address weaknesses.

Insufficient Cryptographic Protection of Data in Transit refers to a security vulnerability in which data being transmitted over a network or between systems is not adequately protected with encryption. This can make it possible for unauthorized third parties to intercept, access, and potentially exploit the data, leading to a range of security risks such as data theft, data manipulation, and unauthorized access to sensitive information. It is important for organizations to use strong cryptographic protocols and algorithms to ensure that data is properly encrypted during transmission to prevent this type of vulnerability.

Example of vulnerable code on different programming languages:


in Java:

				
					import javax.net.ssl.*;
import java.io.*;
import java.net.*;

public class MyClient {

    public static void main(String[] args) throws IOException {
        String urlStr = "https://example.com";
        URL url = new URL(urlStr);
        HttpsURLConnection conn = (HttpsURLConnection) url.openConnection();
        BufferedReader in = new BufferedReader(new InputStreamReader(conn.getInputStream()));
        String inputLine;
        while ((inputLine = in.readLine()) != null) {
            System.out.println(inputLine);
        }
        in.close();
    }
}

				
			


In this Java example, the HTTPS connection is established using the HttpsURLConnection class, but there is no explicit configuration of the SSL/TLS protocol, which means that the default protocol may not be strong enough to provide sufficient cryptographic protection of data in transit. To address this vulnerability, it is recommended to explicitly configure the SSL/TLS protocol and use strong cryptographic algorithms.

• in Python:

				
					import requests

url = "https://example.com"
response = requests.get(url)
print(response.content)

				
			


In this Python example, the requests library is used to send an HTTP GET request to a remote server over HTTPS. However, there is no explicit verification of the server’s SSL/TLS certificate, which means that the connection could potentially be susceptible to a man-in-the-middle attack. To address this vulnerability, it is recommended to verify the SSL/TLS certificate of the server before sending any data.

• in C#:

				
					using System.Net;

public class MyClient {

    static void Main(string[] args) {
        string url = "https://example.com";
        WebClient client = new WebClient();
        string result = client.DownloadString(url);
        Console.WriteLine(result);
    }
}

				
			


In this C# example, the WebClient class is used to download the contents of a webpage over HTTPS, but there is no explicit configuration of the SSL/TLS protocol, which means that the default protocol may not be strong enough to provide sufficient cryptographic protection of data in transit. To address this vulnerability, it is recommended to explicitly configure the SSL/TLS protocol and use strong cryptographic algorithms.

Examples of exploitation Insufficient Cryptographic Protection of Data in Transit

Man-in-the-Middle (MitM) Attack:
An attacker intercepts the communication between a client and a server, and is able to view, modify, or inject data into the communication. If the communication is not properly encrypted, the attacker can easily read and manipulate the data.

Eavesdropping:
An attacker passively intercepts and listens in on the communication between a client and a server. If the communication is not properly encrypted, the attacker can easily read the data.

Data Tampering:
An attacker intercepts the communication between a client and a server, and modifies the data in transit. This can be used to inject malicious content, alter the content of the communication, or even to impersonate the sender or receiver.

Replay Attack:
An attacker intercepts and records the communication between a client and a server, and later replays the communication to perform a malicious action. This can be used to re-send a sensitive data or a sensitive action at a later time, or to gain unauthorized access to a system.

Data Exfiltration:
An attacker intercepts and exfiltrates sensitive data from the communication between a client and a server. If the data is not properly encrypted, the attacker can easily read and extract the sensitive data, which can then be used for malicious purposes such as identity theft, financial fraud, or corporate espionage.

Privilege escalation techniques for Insufficient Cryptographic Protection of Data in Transit

Credential theft:
If the communication between a client and a server is not properly encrypted, an attacker may be able to intercept and steal sensitive information such as usernames and passwords, which can then be used to escalate privileges and gain access to other systems or resources.

Man-in-the-middle attack:
As mentioned earlier, Insufficient Cryptographic Protection of Data in Transit can enable a man-in-the-middle (MitM) attack, where the attacker intercepts the communication and manipulates it. In the context of privilege escalation, a MitM attack may be used to steal or modify data that allows an attacker to gain higher-level access to a system or network.

Session hijacking:
Insufficient Cryptographic Protection of Data in Transit can also make it easier for an attacker to hijack a user’s session and gain access to their account, which can then be used to perform actions with elevated privileges. For example, an attacker could intercept a session cookie or token that is sent in plaintext and use it to impersonate the user and access sensitive resources.

Exploiting vulnerabilities:
Insufficient Cryptographic Protection of Data in Transit may also be used to exploit other vulnerabilities on a system or network, which could then be leveraged to escalate privileges. For example, if an attacker is able to intercept unencrypted network traffic, they may be able to identify vulnerabilities in the software being used by the client or server, which could then be exploited to gain higher privileges.
