Google Go JoinPath/URL.JoinPath path traversal
|CVSS Meta Temp Score|
CVSS is a standardized scoring system to determine possibilities of attacks. The Temp Score considers temporal factors like disclosure, exploit and countermeasures. The unique Meta Score calculates the average score of different sources to provide a normalized scoring system.
|Current Exploit Price (≈)|
Our analysts are monitoring exploit markets and are in contact with vulnerability brokers. The range indicates the observed or calculated exploit price to be seen on exploit markets. A good indicator to understand the monetary effort required for and the popularity of an attack.
|CTI Interest Score|
Our Cyber Threat Intelligence team is monitoring different web sites, mailing lists, exploit markets and social media networks. The CTI Interest Score identifies the interest of attackers and the security community for this specific vulnerability in real-time. A high score indicates an elevated risk to be targeted for this vulnerability.
A vulnerability, which was classified as critical, has been found in Google Go (Programming Language Software) (affected version not known). Affected by this issue is the function
JoinPath/URL.JoinPath. The manipulation with an unknown input leads to a path traversal vulnerability. Using CWE to declare the problem leads to CWE-24. The software uses external input to construct a pathname that should be within a restricted directory, but it does not properly neutralize "../" sequences that can resolve to a location that is outside of that directory. Impacted is confidentiality, integrity, and availability. CVE summarizes:
JoinPath and URL.JoinPath do not remove ../ path elements appended to a relative path. For example, JoinPath("https://go.dev", "../go") returns the URL "https://go.dev/../go", despite the JoinPath documentation stating that ../ path elements are removed from the result.
The weakness was released 09/14/2022. The advisory is available at go.dev. This vulnerability is handled as CVE-2022-32190 since 05/31/2022. Technical details are known, but there is no available exploit. The structure of the vulnerability defines a possible price range of USD $5k-$25k at the moment (estimation calculated on 10/17/2022). This vulnerability is assigned to T1006 by the MITRE ATT&CK project.
There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.
