## What is CVE-2025-34154?

CVE-2025-34154 is a critical path traversal vulnerability in Synergetic Data Systems Inc. UnForm Server Manager, published on 13 Aug 2025. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

UnForm Server Manager versions prior to 10.1.12 expose an unauthenticated file read vulnerability via its log file analysis interface. The flaw resides in the arc endpoint, which accepts a fl parameter to specify the log file to be opened. Due to insufficient input validation and lack of path sanitization, attackers can supply relative paths to access arbitrary files on the host system — including sensitive OS-level files — without authentication.

Weakness: CWE-22 (Improper Limitation of a Pathname to a Restricted Directory)
