Technical details

A stack-based buffer overflow vulnerability exists in the WOSDefaultHttpModule.dll component of Gladinet Triofox Server Agent. The flaw is triggered when the GladServerAgentService.exe, which listens on TCP port 7878, processes a maliciously crafted, overly long URL path starting with the /woshome prefix. An unauthenticated remote attacker can exploit this to overwrite stack memory, potentially leading to arbitrary code execution with the privileges of the service. The vulnerability was identified in version 17.1.10488.57063.
