Directory traversal vulnerability in include/head_chat.inc.php in php Help Agent 1.0 and 1.1 Full allows remote attackers to include and execute arbitrary local files via a .. (dot dot) in the content parameter. NOTE: in some environments, this can be leveraged for remote file inclusion by using a UNC share pathname or an ftp, ftps, or ssh2.sftp URL.
The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory.
