CWE-ID:
CWE-22 - Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform directory traversal attacks.
The vulnerability exists due to input validation error when processing directory traversal sequences. The software fails to prevent existing globally-installed binaries to be overwritten by other package installations. For example, if a package was installed globally and created a serve
binary, any subsequent installs of packages that also create a serve
binary would overwrite the first binary. This only affects files in /usr/local/bin
A remote attacker can overwrite arbitrary files on the system.
MitigationInstall update from vendor's website.
