Summary

Synerion TimeNet version 9.21 contains a directory traversal vulnerability where, on the "Name" parameter, the attacker can return to the root directory and open the host file. This might give the attacker the ability to view restricted files, which could provide the attacker with more information required to further compromise the system.

Exploit prediction

0.95% chance of exploitation in the next 30 days, higher than 61% of all scored CVEs (FIRST EPSS, 2026-11-08).
