Unauthenticated configuration disclosure via session-validation bypass
Published Mar 20, 2024 · Updated Aug 28, 2024
Path traversal in process_post on DrayTek Vigor3910 4.3.2.5 allows remote attackers to export the router configuration via a POST request. The process_post function accepts attacker-controlled request parameters without enforcing session validation before invoking the configuration-export operation. No authentication is required; the disclosed plaintext configuration exposes sensitive router information, but no data modification or service interruption is reported.
