Unauthenticated stack corruption via unbounded URI concatenation
Published May 27, 2026 · Updated May 27, 2026
Stack-based buffer overflow in Gladinet Triofox Server Agent before 17.3.10565.57509 allows remote attackers to corrupt memory via a /woshome path. WOSDefaultHttpModule.dll copies ServerAgentDir into a fixed-size stack buffer, then uses wcscat to append the attacker-controlled URI without a destination bound. The unauthenticated request reaches TCP port 7878, and the resulting memory corruption can crash the service or redirect execution.
