Buffer Over-read

Vulnerability Assessment as a Service (VAaaS)

Tests systems and applications for vulnerabilities to address weaknesses.

Buffer Over-read is a type of vulnerability that occurs when a program tries to read data beyond the end of a buffer in memory. This can happen when a program does not properly validate the size of the input before copying it into a buffer, or when a buffer is not properly initialized or cleared before being used. As a result, the program may read data that was not intended to be read, leading to unexpected behavior, crashes, or security issues such as leaking sensitive information.

Example of vulnerable code on different programming languages:


in C:

				
					char buffer[10];
strcpy(buffer, "Hello, world!");
printf("%s\n", buffer);

				
			


In this example, the buffer has a size of 10, but the string being copied into it is longer than that. This will result in a buffer over-read, as the program will continue reading beyond the end of the buffer to try to copy the entire string.

• in Python:

				
					data = b"Hello, world!"
print(data[0:15])

				
			


In this example, the program is trying to print the first 15 bytes of the data variable, even though it only has a length of 13 bytes. This will result in a buffer over-read, as the program will try to read bytes beyond the end of the data variable.

• in Java:

				
					byte[] buffer = new byte[10];
System.in.read(buffer, 0, 15);
System.out.println(new String(buffer));

				
			


In this example, the program is reading up to 15 bytes of input into a buffer that only has a size of 10 bytes. This will result in a buffer over-read, as the program will try to read bytes beyond the end of the buffer. Additionally, the program is converting the byte array to a string without specifying the character encoding, which could result in unexpected behavior.

Examples of exploitation Buffer Over-read

Information disclosure:

If a buffer over-read vulnerability allows an attacker to read data that was not intended to be read, they may be able to extract sensitive information such as passwords, cryptographic keys, or other secrets. For example, if a program stores a user’s password in memory, a buffer over-read vulnerability could allow an attacker to read that password and use it to gain unauthorized access to the user’s account.

Denial of service:

If a buffer over-read vulnerability causes a program to crash or enter an infinite loop, an attacker may be able to exploit this to cause a denial of service (DoS) attack. For example, an attacker could send a specially crafted input that triggers the vulnerability, causing the program to crash and become unavailable.

Code execution:

In some cases, a buffer over-read vulnerability may be combined with other vulnerabilities to enable code execution. For example, if an attacker can overwrite a function pointer in memory through a buffer over-read vulnerability, they may be able to redirect program execution to their own code and take control of the system. This is known as a “return-oriented programming” (ROP) attack.

Privilege escalation techniques for Buffer Over-read

Exploit a kernel vulnerability:

If a buffer over-read vulnerability exists in a user-level program that communicates with the kernel, an attacker may be able to use the vulnerability to trigger a kernel vulnerability and escalate privileges. For example, if a user-level program passes data to the kernel through a system call, an attacker could exploit the buffer over-read vulnerability to trigger a buffer overflow in the kernel, which could then be used to execute arbitrary code with kernel privileges.

Exploit a privileged process:

If a buffer over-read vulnerability exists in a process that runs with elevated privileges, such as a setuid binary or a system service, an attacker may be able to use the vulnerability to escalate their own privileges. For example, if a setuid binary has a buffer over-read vulnerability, an attacker could exploit the vulnerability to overwrite a function pointer in memory and execute their own code with the privileges of the setuid binary.

Exploit a vulnerability in a related component:

If a buffer over-read vulnerability exists in one component of a system, an attacker may be able to use the vulnerability to exploit a vulnerability in a related component and escalate privileges. For example, if a web server has a buffer over-read vulnerability, an attacker could exploit the vulnerability to read sensitive data from memory, such as credentials for a database server. They could then use those credentials to connect to the database server and exploit a vulnerability in the database server to escalate their privileges.

General methodology and checklist for Buffer Over-read

Methodology:

  1. Identify the target application: The first step is to identify the target application that will be tested for buffer over-read vulnerabilities. This could be a standalone program, a library, or a web application.

  2. Identify input sources: Next, identify the sources of input that the application accepts. This could include user input from a command line, data read from a file, or data received over a network.

  3. Design test cases: Design test cases that include inputs that exceed the size of the buffer or that are malformed in some way. These test cases should be designed to trigger buffer over-read vulnerabilities.

  4. Run the tests: Run the test cases against the target application and observe its behavior. If the application crashes or produces unexpected behavior, it may be an indication of a buffer over-read vulnerability.

  5. Analyze results:Analyze the results of the tests to determine if any buffer over-read vulnerabilities were identified. If vulnerabilities were found, prioritize them based on their severity and likelihood of being exploited.

  6. Mitigate vulnerabilities: Report the vulnerabilities to the application’s developers and work with them to develop and implement a mitigation plan. This may include modifying the application’s code to prevent buffer over-read vulnerabilities or adding input validation to ensure that input data does not exceed the size of the buffer.

  7. Re-test: After the vulnerabilities have been mitigated, re-test the application to ensure that the changes did not introduce new vulnerabilities.

Checklist:

  1. Identify the target application and its input sources.

  2. Understand the application’s data structures and memory layout.

  3. Identify buffers in the application that may be vulnerable to over-reads.

  4. Identify points in the application where input is copied to a buffer.

  5. Create test cases that exceed the size of the buffer or that contain malformed data.

  6. Use a debugger to step through the code and observe how the application handles the input.

  7. Look for crashes, unexpected behavior, or memory access violations that may indicate a buffer over-read vulnerability.

  8. Use static analysis tools to identify potential buffer over-read vulnerabilities in the code.

  9. Verify that input validation is performed to prevent input that exceeds the size of the buffer.

  10. Verify that the application handles input errors gracefully without crashing or leaking sensitive information.

  11. Verify that the application does not expose sensitive information through error messages or other output.

  12. Verify that the application is not vulnerable to other types of memory-related vulnerabilities, such as buffer overflows or format string vulnerabilities.

  13. Work with the application’s developers to develop and implement a mitigation plan for any identified vulnerabilities.

  14. Re-test the application after mitigation to verify that the vulnerabilities have been addressed and that no new vulnerabilities have been introduced.

Average CVSS score of stack Buffer Over-read

The Common Vulnerability Scoring System (CVSS) provides a framework for assessing the severity of security vulnerabilities, taking into account the potential impact on confidentiality, integrity, and availability of affected systems. The CVSS score is rated on a scale from 0 to 10, with higher scores indicating more severe vulnerabilities.

The CVSS score for a stack buffer over-read vulnerability depends on various factors such as the impact of the vulnerability on the system, the level of access required to exploit the vulnerability, and the availability of mitigating factors such as input validation and memory protection mechanisms. Therefore, it is not possible to provide an average CVSS score for all stack buffer over-read vulnerabilities.

However, stack buffer over-read vulnerabilities are generally considered to be moderately severe to highly severe, depending on the specific circumstances of the vulnerability. In some cases, a stack buffer over-read vulnerability may lead to information disclosure or denial of service attacks, while in other cases it may lead to arbitrary code execution or privilege escalation. Therefore, it is important to take stack buffer over-read vulnerabilities seriously and to address them promptly to reduce the risk of exploitation.

Top 10 CVES related to Buffer Over-read

CVE-2023-26253 – In Gluster GlusterFS 11.0, there is an xlators/mount/fuse/src/fuse-bridge.c notify stack-based buffer over-read.

CVE-2023-25602 – A stack-based buffer overflow in Fortinet FortiWeb 6.4 all versions, FortiWeb versions 6.3.17 and earlier, FortiWeb versions 6.2.6 and earlier, FortiWeb versions 6.1.2 and earlier, FortiWeb versions 6.0.7 and earlier, FortiWeb versions 5.9.1 and earlier, FortiWeb 5.8 all versions, FortiWeb 5.7 all versions, FortiWeb 5.6 all versions allows attacker to execute unauthorized code or commands via specially crafted command arguments.

CVE-2023-25563 – GSS-NTLMSSP is a mechglue plugin for the GSSAPI library that implements NTLM authentication. Prior to version 1.2.0, multiple out-of-bounds reads when decoding NTLM fields can trigger a denial of service. A 32-bit integer overflow condition can lead to incorrect checks of consistency of length of internal buffers. Although most applications will error out before accepting a singe input buffer of 4GB in length this could theoretically happen. This vulnerability can be triggered via the main `gss_accept_sec_context` entry point if the application allows tokens greater than 4GB in length. This can lead to a large, up to 65KB, out-of-bounds read which could cause a denial-of-service if it reads from unmapped memory. Version 1.2.0 contains a patch for the out-of-bounds reads.
