What is CVE-2026-8359?
CVE-2026-8359 is a high-severity vulnerability in Gladinet Triofox, published on 27 May 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
When processing a request with a URL path starting with /status or /sysinfo, WOSHttpStatusModule.dll is to be loaded to handle such URL patterns. The WOSBin_LoadHttpModule function in the dll would be called to set up a "module" object for that module. However, WOSHttpStatusModule.dll is not present in the installation. As a result, a function pointer to WOSBin_LoadHttpModule (which would have been in the export table in WOSHttpStatusModule.dll) is set to NULL, resulting in calling a function at address 0.
Weakness: CWE-476
