CVE-2024-52006 pertains to a vulnerability in Git, a widely used distributed revision control system. This vulnerability allows for potential credential leakage due to the improper handling of Carriage Return characters by certain ecosystems, notably .NET and node.js. The vulnerability was classified with a CVSS score of 2.1, indicating a low severity level. Although it presents a lower risk compared to other vulnerabilities, it is still essential for organizations to address it to prevent possible credential exposure.
The exploitability of this vulnerability is categorized as low, and it has not been reported as actively exploited in the wild. Nevertheless, organizations using Debian with Git should consider this vulnerability as part of their threat landscape. The urgency for defenders is moderate, given its low severity, but organizations are still advised to upgrade their Git installations to the latest versions to eliminate this risk.
Users unable to upgrade are advised to avoid cloning from untrusted URLs, particularly when dealing with recursive clones. This caution is crucial in mitigating potential exposure to malicious repositories that could exploit this vulnerability and leak stored credentials.
Overall, while the severity is classified as low, organizations should still prioritize addressing this vulnerability within their patch management cycles to maintain security integrity.
Vulnerability Details
The vulnerability allows credential leakage due to the way Carriage Return characters are treated by Git and certain credential helpers. The issue has been addressed in several Git release versions, including v2.48.1, v2.47.2, and earlier versions down to v2.40.4. Organizations are urged to upgrade to these versions to safeguard against this vulnerability.
Technical Analysis
Root cause analysis indicates that the handling of Carriage Return characters in the Git protocol can lead to credential exfiltration, especially when interacting with untrusted repositories. The attack vector for this vulnerability is classified as NETWORK, meaning it can be exploited remotely. The attack complexity is considered low, requiring only active user interaction to trigger the vulnerability.
This vulnerability does not require elevated privileges to exploit, as it can be executed without special permissions. Furthermore, user interaction is essential, as the exploitation depends on the user cloning repositories from untrusted sources. The impact on confidentiality is none, while the integrity impact is low, as it could result in unauthorized disclosure of credentials.
Organizations should be aware of the potential risks associated with this vulnerability, especially in environments where Git is extensively used for version control and collaboration.
Risk & Impact Analysis
Risk to organizations includes potential credential leakage through untrusted Git operations. Although the severity is low, the lack of safeguards can lead to significant exposure if exploited. Organizations should assess their usage of Git and the environments in which it operates to determine the potential blast radius of this vulnerability.
Given that the vulnerability is not currently exploited in the wild, organizations should prioritize remediation in their patch cycles. However, proactive measures should be taken to avoid interacting with untrusted repositories to prevent inadvertent credential exposure.
Exploitation Status
Signal | Status |
|---|---|
Known Exploit | No |
Public PoC | No |
Actively Exploited | No |
Ransomware Use | No |
Affected Versions
The affected versions of Git include all versions prior to the following releases: v2.48.1, v2.47.2, v2.46.3, v2.45.3, v2.44.3, v2.43.6, v2.42.4, v2.41.3, and v2.40.4. Organizations utilizing Debian Linux 11.0 should ensure they are running an updated version of Git.
Mitigation & Remediation
