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

Exploit availability: Yes

Description

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

The vulnerability exists due to input validation error when processing directory traversal sequences in filenames during file upload within Action File Upload Interceptor. A remote attacker can upload a specially crafted file to the server into an arbitrary directory.

Successful exploitation may allow an attacker to upload an arbitrary file and execute it on the server, leading to a full system compromise.

Mitigation

Install update from vendor's website.
