Description
DedeCMS before 5.7 contains a file inclusion vulnerability in plus/carbuyaction.php that allows remote unauthenticated attackers to control the include path by manipulating the uninitialized code parameter passed to require_once. Attackers can supply path traversal sequences ../../ to include arbitrary local files outside the intended payment directory, potentially achieving local file disclosure. Exploitation evidence was first observed by the Shadowserver Foundation on 2023-10-18.
