Multiple directory traversal vulnerabilities in PhpMyChat Plus 1.9 and earlier allow remote attackers to read arbitrary files via a .. (dot dot) in the ChatPath parameter to (1) avatar.php, (2) colorhelp_popup.php, (3) color_popup.php, (4) index.php, (5) index1.php, (6) lib/connected_users.lib.php, (7) lib/index.lib.php, and (8) phpMyChat.php3; and the (9) L parameter to logs.php. NOTE: CVE analysis suggests that vector 1 might be incorrect.
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.
