Multiple PHP remote file inclusion vulnerabilities in Turnkey Web Tools PHP Live Helper 1.8 allow remote attackers to include and execute arbitrary PHP code via the abs_path parameter in (1) initiate.php, (2) waiting.php, (3) welcome.php, (4) admin/index.php, (5) javascript.php, (6) checkchat.php, and (7) blank.php.

Directory traversal vulnerability in (1) initiate.php and (2) possibly other PHP scripts in Turnkey Web Tools PHP Live Helper 1.8, and possibly later versions, allows remote authenticated users to include and execute arbitrary local files via directory traversal sequences in the language cookie, as demonstrated by uploading PHP code in a gl_session cookie to users.php, which causes the code to be stored in error.log, which is then included by initiate.php.

Cross-site scripting (XSS) vulnerability in chat.php in PHP Live Helper allows remote attackers to inject arbitrary web script or HTML via the PHPSESSID parameter.
