CVE-2023-47251 is a medium-severity vulnerability rated 6.5/10 on the CVSS scale. In mprivacy-tools before 2.0.406g in m-privacy TightGate-Pro Server, a Directory Traversal in the print function of the VNC service allows authenticated attackers (with access to a VNC session) to automatically transfer malicious PDF documents by moving them into the .spool directory, and then sending a signal to the VNC service, which automatically transfers them to the connected VNC client's filesystem.. EPSS estimates a 1.73% chance of exploitation in the next 30 days.
