Multiple vulnerabilities have been identified in Kaqoo Auction, which could be exploited by attackers to execute arbitrary commands. These issues are due to input validation errors in various scripts (e.g. "include/core/support.inc.php" or "include/core/function.inc.php") when processing the "install_root" parameter, which could be exploited by remote attackers to include malicious scripts and execute arbitrary commands with the privileges of the web server.
