Does this matter?

High impact if exploited, but EPSS currently rates exploitation as unlikely (0.27%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.

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.
