CVE-2026-8359
CWE-476Published: May 27, 2026· Updated: May 29, 2026
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.
