Improper Link Resolution Before File Access ('Link Following')

CVE-2024-9341

Medium
5.8/10

Summary

A flaw was found in Go. When FIPS mode is enabled on a system, container runtimes may incorrectly handle certain file paths due to improper validation in the containers/common Go library. This flaw allows an attacker to exploit symbolic links and trick the system into mounting sensitive host directories inside a container. This issue also allows attackers to access critical host files, bypassing the intended isolation between containers and the host system. This vulnerability affects github.com/containers/common versions through 0.57.6, 0.58.0 through 0.58.4, 0.59.0 through 0.60.3, 1.0.0, and 1.0.1.

CWE-59 - Improper Link Resolution Before File Access

'Improper link resolution before file access' occurs when software accesses a file resource but fails to verify that the file isn't a link or shortcut to another file. An attacker can potentially gain access to arbitrary files and from there the impact can vary, depending on the application, from sensitive data exposure to remote code execution.
