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:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote user to delete arbitrary files and directories writable by the SABnzbd process.

The vulnerability exists due to path traversal in the orphan job management API handlers when handling a user-supplied value parameter. A remote user can send a specially crafted API request with an absolute path to delete arbitrary files and directories writable by the SABnzbd process.

The issue affects _api_delete_orphan, _api_add_orphan, and _api_delete_all_orphan. The API key is required, and user-supplied absolute paths override the intended download directory because os.path.join() discards the base path when the second argument is absolute.
