CVE-2026-8361Public exploitNetwork attack vector

Unauthenticated file disclosure via unnormalized URL paths

Published May 27, 2026 · Updated May 27, 2026

Path traversal in Gladinet Triofox Server Agent before 17.3.10565.57509 allows remote attackers to read arbitrary files. WOSDefaultHttpModule.dll appends the attacker-controlled /woshome URI path to its installation directory with wcscat without rejecting traversal segments. Unauthenticated access to TCP port 7878 exposes files readable by the Server Agent account, with no demonstrated write or service-interruption impact.
