Last modified Jun 17, 2026

CVE-2023-31450 is a medium-severity vulnerability rated 4.7/10 on the CVSS scale. A path traversal vulnerability was identified in the SQL v2 sensors in PRTG 23.2.84.1566 and earlier versions where an authenticated user with write permissions could trick the SQL v2 sensors into behaving differently for existing files and non-existing files. This made it possible to traverse paths, allowing the sensor to execute files outside the designated custom sensors folder. EPSS estimates a 0.43% chance of exploitation in the next 30 days.
