CVE-2025-34118Public exploitNetwork attack vector

Unauthenticated file disclosure via encoded path traversal

Published Jul 16, 2025 · Updated May 15, 2026

Path traversal in Linknat Limited VOS Manager before 2.1.9.07 allows remote attackers to read arbitrary server files without authentication. Localized /eng/, /chs/, and /cht/ file-loading routes accept encoded dot segments such as %c0%ae%c0%ae and resolve the resulting path outside the web root. No credentials or user interaction are required, and successful requests disclose server files readable by the web service account.
