Summary

ServersCheck Monitoring Software through 14.3.3 allows local users to cause a denial of service (menu functionality loss) by creating an LNK file that points to a second LNK file, if this second LNK file is associated with a Start menu. Ultimately, this behavior comes from a Directory Traversal bug (via the sensor_details.html id parameter) that allows creating empty files in arbitrary directories.

Exploit prediction

2.68% chance of exploitation in the next 30 days, higher than 85% of all scored CVEs (FIRST EPSS, 2026-11-09).
