CVE-2023-26036Public exploitNetwork attack vector

PHP code execution via incomplete path sanitization

Published Feb 25, 2023 · Updated Mar 10, 2025

Path traversal in ZoneMinder before 1.36.33 and 1.37.0 through 1.37.32 allows remote authenticated users to execute local PHP files. The web/index.php view handler passes a detaintPath-filtered view value to require_once, but detaintPath removes ../ only once, allowing ..././ to become ../. Access to the authenticated web interface and an existing local PHP file are required; the flaw does not itself upload a file.
