CVE-2022-25498Public exploitNetwork attack vector

Unauthenticated PHP code execution via configuration injection

Published Mar 15, 2022 · Updated Aug 3, 2024

Code injection in CuppaCMS 1.0 allows remote attackers to execute arbitrary PHP code through a crafted configuration request. The saveConfigData function in /classes/ajax/Functions.php decodes attacker-controlled JSON and writes its code value into executable /Configuration.php content without validation. No authentication is required, and successful exploitation installs a web shell that runs commands in the web server's security context.
