CVE-2024-55947 is a high-severity vulnerability affecting Gogs, an open-source self-hosted Git service. This vulnerability allows malicious users to write files to arbitrary paths on the server, which can result in unauthorized SSH access. The CVSS score for this vulnerability is 8.7, indicating a high level of risk for organizations using Gogs. The vulnerability is significant as it opens the door for attackers to exploit the system, potentially compromising sensitive data and server integrity.
Organizations using Gogs should prioritize patching immediately to prevent unauthorized access and ensure the integrity of their systems. The vulnerability was fixed in version 0.13.1, and failure to update could leave systems exposed to significant risks.
As of now, there are no known exploits or public proof-of-concept (PoC) for this vulnerability. However, given the nature of the vulnerability, it is essential for organizations to take proactive measures to mitigate risks.
The urgency of addressing this vulnerability cannot be overstated, as attackers may leverage it to gain unauthorized access to critical systems.
Vulnerability Details
The official description of CVE-2024-55947 states that it allows a malicious user to write a file to an arbitrary path on the server to gain SSH access. The vulnerability has been classified under CWE-22, indicating a path traversal issue.
The CVSS score of 8.7 indicates the severity of this vulnerability, categorized as high. The vulnerability falls under the following metrics: penetration testing methodologies can be employed to identify such vulnerabilities in the future.
Technical Analysis
The root cause of this vulnerability lies in the improper validation of file paths, allowing users to exploit the system by writing files to unauthorized locations. The attack vector is network-based, requiring low attack complexity and privileges, which means that even users with limited access can potentially exploit this vulnerability.
No user interaction is required for the exploitation of this vulnerability, which increases the risk to organizations. The impact on confidentiality, integrity, and availability is classified as high, indicating that an attacker could gain full control over the affected system.
Risk & Impact Analysis
Risk to organizations includes unauthorized access to sensitive data and potential full compromise of the server. Given the characteristics of this vulnerability, the blast radius could extend to any user with network access to the affected Gogs instance. The urgency of remediation is high, as organizations must prioritize patching to protect their assets.
