Description

This security bulletin contains information about 1 vulnerability.


1) Path traversal (CVE-ID: N/A)

CWE-ID: CWE-22 - Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N/E:U/U:Amber


The vulnerability allows a remote attacker to perform directory traversal attacks.

The vulnerability exists due to input validation error in Ghidra's extension installer. When a user installs a ZIP extension through File -> Install Extensions, the code extracts files without validating the entry names. A malicious ZIP with ../ sequences in filenames can write files outside the intended extension directory.
