Multiple vulnerabilities have been identified in 29o3 CMS, which could be exploited by attackers to execute arbitrary commands. These issues are caused by input validation errors in various scripts (e.g. "lib/page/pageDescriptionObject.php", "lib/layout/layoutHeaderFuncs.php", "lib/layout/layoutManager.php" and "lib/layout/layoutParser.php") when processing the "LibDir" parameter, which could be exploited by remote attackers to include remote scripts and execute arbitrary commands with the privileges of the web server.
