CVE-2026-8359: CWE-476 NULL pointer dereference in Gladinet Triofox
CVE-2026-8359 is a high-severity vulnerability in Gladinet Triofox caused by a NULL pointer dereference. The issue arises when processing requests with URL paths starting with /status or /sysinfo, which require loading the WOSHttpStatusModule.dll. Since this DLL is missing from the installation, the function pointer to WOSBin_LoadHttpModule is set to NULL, leading to a call at address 0 and causing a denial of service.
AI Analysis
Technical Summary
This vulnerability involves a NULL pointer dereference in Gladinet Triofox. When handling requests with URL paths beginning with /status or /sysinfo, the software attempts to load WOSHttpStatusModule.dll and call its exported function WOSBin_LoadHttpModule to set up a module object. However, because WOSHttpStatusModule.dll is not present in the installation, the function pointer is NULL. Invoking this NULL pointer results in a call to address 0, causing the application to crash or become unavailable.
Potential Impact
The vulnerability leads to a denial of service condition by crashing the application when certain URL paths are requested. There is no indication of confidentiality or integrity impact. No known exploits are reported in the wild.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or temporary workaround is currently documented. Until a patch is available, restricting access to the affected URL paths or disabling the related functionality may reduce exposure.
