CVE-2026-8359: CWE-476 NULL pointer dereference in Gladinet Triofox
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.
AI Analysis
Technical Summary
Gladinet Triofox contains a NULL pointer dereference vulnerability (CWE-476) identified as CVE-2026-8359. The vulnerability arises because the WOSHttpStatusModule.dll, which should handle requests with URL paths starting with /status or /sysinfo, is absent from the installation. Consequently, the function pointer to WOSBin_LoadHttpModule is NULL. When the software attempts to call this function pointer, it results in a call to address 0, causing a denial of service condition. The CVSS 3.1 base score is 7.5, reflecting network attack vector, low attack complexity, no privileges required, no user interaction, unchanged scope, no confidentiality or integrity impact, but high impact on availability.
Potential Impact
The vulnerability leads to a denial of service (DoS) condition by causing the application to attempt to execute a NULL function pointer. This can disrupt the availability of the affected Gladinet Triofox service. There is no impact on confidentiality or integrity according to the CVSS vector. No known exploits are currently reported in the wild.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Since no official fix or temporary workaround is currently documented, users should monitor vendor communications for updates. In the meantime, restricting access to the affected URL paths (/status and /sysinfo) at network or application layers may reduce exposure.
