Path Traversal in Rancher Fleet ImageScan GitRepo Path Handler
A path traversal vulnerability was found in Fleet's ImageScan subsystem in Rancher Fleet 0.12.0 up to 0.12.16, 0.13.0 up to 0.13.12, 0.14.0 up to 0.14.7 and 0.15.0 up to 0.15.3 could be used to traverse outside of the intended directory, causing a denial of service.
Weakness Type
Relative Path Traversal
The software uses external input to construct a pathname that should be within a restricted directory, but it does not properly neutralize sequences such as ".." that can resolve to a location that is outside of that directory. This allows attackers to traverse the file system to access files or directories that are outside of the restricted directory.
