CVE-2024-32465 is a high-severity vulnerability identified in Git, a widely used revision control system. This vulnerability allows attackers to bypass critical security protections when cloning repositories, particularly those that may not be trusted. As a result, it poses a significant risk to organizations relying on Git for version control, especially in environments where untrusted repositories are accessed.
The CVSS score associated with this vulnerability is 7.3, indicating a high level of severity. The implications of this vulnerability could lead to unauthorized access to sensitive data and manipulation of repository contents. Organizations must assess their usage of Git and related systems to determine their exposure to this vulnerability.
The vulnerability was published on May 14, 2024, and has been actively analyzed since. It is crucial for organizations to prioritize remediation efforts, as attackers may leverage this vulnerability to exploit untrusted repositories. Immediate action is recommended to mitigate potential risks.
Organizations should prioritize patching immediately. The vendor has released patches in versions 2.45.1, 2.44.1, 2.43.4, 2.42.2, 2.41.1, 2.40.2, and 2.39.4. Additionally, as a temporary workaround, users are advised to avoid using Git in repositories obtained via archives from untrusted sources.
Vulnerability Details
Git is a revision control system that enables users to track changes in source code. This vulnerability arises from the ability to clone repositories without proper verification, especially when dealing with untrusted sources. The specific weakness is classified under CWE-22, which relates to improper restriction of operations within the bounds of a memory buffer.
The vulnerability has been assigned a CVSS score of 7.3, indicating a high severity level, primarily due to the potential for high confidentiality, integrity, and availability impacts. The affected versions include multiple releases of Git: all versions prior to 2.39.4, and 2.40.0 to 2.40.2, 2.42.0 to 2.42.2, and 2.43.0 to 2.43.4.
The vulnerability was disclosed on May 14, 2024, and it is essential to keep systems updated with the latest security patches to mitigate any potential risks associated with this vulnerability.
Technical Analysis
The root cause of this vulnerability is linked to the way Git handles cloning operations from untrusted sources. Attackers may exploit this flaw by tricking users into executing commands that could run unauthorized scripts or commands within the context of the repository.
The attack vector is classified as physical, requiring local access to the vulnerable system. The attack complexity is low, indicating that this vulnerability can be exploited easily with minimal technical skill. No privileges are required for exploitation, but user interaction is necessary to trigger the vulnerability.
This vulnerability has significant impacts on confidentiality, integrity, and availability due to the potential for malicious code execution and unauthorized access to data within the Git repository.
Risk & Impact Analysis
Risk to organizations includes unauthorized access and manipulation of source code, leading to potential data breaches, loss of intellectual property, and compromised software integrity. The blast radius could be extensive, affecting not only the compromised repository but also any dependent systems and projects relying on the affected code.
Given the high CVSS score and the potential impact, organizations using Git should assess their exposure and deploy the necessary patches promptly. The urgency for organizations to address this vulnerability is high, as it may be actively exploited in the wild.

Affected Versions
The affected versions of Git are all versions prior to 2.39.4, and those from versions 2.40.0 to 2.40.2, 2.42.0 to 2.42.2, and 2.43.0 to 2.43.4. Additionally, specific versions of Debian and Fedora are also impacted.
Mitigation & Remediation
To mitigate this vulnerability, organizations should apply the relevant patches as soon as possible. The patched versions include 2.45.1, 2.44.1, 2.43.4, 2.42.2, 2.41.1, 2.40.2, and 2.39.4. For those unable to immediately update, it is advised to avoid using Git in repositories obtained via archives from untrusted sources.
For enhanced security, organizations should consider conducting regular security assessments through application security assessments and establish robust security policies to manage the use of repositories.
Detection Guidance
Organizations should monitor logs for any unusual access patterns or commands executed within Git repositories. Indicators of compromise may include unexpected repository changes or unauthorized script executions. Behavioral anomalies should be analyzed to detect any unauthorized access attempts.
AppSecure Threat Intelligence Insight
This vulnerability highlights the ongoing risks associated with using version control systems in environments with potentially untrusted sources. As the use of Git continues to grow, organizations must prioritize securing their repositories against such vulnerabilities.
Security teams should learn from this incident to improve their defensive strategies. Regular training and awareness programs can help in identifying and responding to security threats effectively. Organizations should also leverage resources such as penetration testing methodologies to enhance their resilience against future vulnerabilities.
Furthermore, organizations should adopt a proactive approach to vulnerability management by conducting regular assessments and integrating security practices into their development life cycle. This will ensure better protection against similar vulnerabilities in the future.
