CVE-2022-29804 is a high-severity vulnerability that affects the Clean function in the path/filepath package of Golang's Go language. This vulnerability allows incorrect conversion of certain invalid paths to valid absolute paths, potentially enabling a directory traversal attack. Such an attack could lead to unauthorized access to sensitive files or directories, significantly impacting the security posture of applications utilizing the affected versions.
The vulnerability has a CVSS score of 7.5, indicating a high severity level. This score reflects the potential for attackers to exploit this vulnerability over a network with low complexity, requiring no privileges or user interaction. The confidentiality impact is assessed as high, emphasizing the risk of unauthorized information disclosure.
Given the nature of the vulnerability and its potential implications, organizations using affected versions of Golang should prioritize patching immediately to mitigate associated risks. The vulnerability was published on August 10, 2022, and remains relevant with ongoing threat landscapes.
Organizations should be aware that as of now, there are no known exploits available for this vulnerability, but the potential for exploitation exists, making prompt remediation crucial.
Vulnerability Details
The vulnerability description states that the issue arises from the incorrect conversion of certain invalid paths, which can result in valid absolute paths being generated. Specifically, this affects versions of Go prior to 1.17.11 and 1.18.3 when operating on Windows systems. The specific weakness is classified under CWE-22, indicating a directory traversal vulnerability.
The CVSS score of this vulnerability is 7.5, categorized as high severity. The implications of this score are significant, as it indicates a network-exploitable vulnerability that requires low attack complexity and no privileges or user interaction. The potential impact on confidentiality is high, while integrity and availability impacts are noted as none.
Technical Analysis
Root cause analysis reveals that the vulnerability is a result of improper handling of invalid paths within the Clean function. Attackers could exploit this flaw to traverse directories unexpectedly, potentially gaining access to sensitive files. The attack vector is classified as network-based, meaning it can be exploited remotely with low complexity.
The attack complexity is assessed as low, indicating that even unskilled attackers could exploit this vulnerability if they understand how to construct the malicious paths. No privileges are required for exploitation, and user interaction is not necessary.
The confidentiality impact is rated high due to the potential for sensitive data exposure. However, there is no impact on integrity or availability, which indicates that the primary risk is the unauthorized disclosure of information.
Risk & Impact Analysis
The real-world risk associated with CVE-2022-29804 revolves around the potential for directory traversal attacks, which could allow unauthorized users to access sensitive files. This vulnerability is particularly concerning for applications that handle sensitive data or operate in environments with limited access controls.
Organizations should assess the exposure of their applications to this vulnerability. The blast radius could be significant, especially for applications that rely heavily on file path manipulations. Given the high CVSS score and the potential for exploitation, organizations must address this vulnerability in their priority patch cycle.
