Multiple PHP remote file inclusion vulnerabilities in PHPOpenChat 3.0.1 and earlier allow remote attackers to execute arbitrary PHP code via the phpbb_root_path parameter to (1) poc_loginform.php or (2) phpbb/poc.php, the poc_root_path parameter to (3) phpbb/poc.php, (4) phpnuke/ENGLISH_poc.php, (5) phpnuke/poc.php, or (6) yabbse/poc.php, or (7) the sourcedir parameter to yabbse/poc.php.

Cross-site scripting (XSS) vulnerability in PHPOpenChat v3.x allows remote attackers to inject arbitrary web script or HTML via (1) the chatter parameter to regulars.php or (2) the chatter, chatter1, chatter2, chatter3, or chatter4 parameters to register.php.

Multiple cross-site scripting (XSS) vulnerabilities in PHPOpenChat 3.0.2 allow remote attackers to inject arbitrary web script or HTML via the (1) title or (2) content parameter to profile.php and profile_misc.php, (3) the profile fields in userpage.php, (4) subject or (5) body in mail.php, or (8) disinvited_chatter or (7) invited_chatter parameter to invite.php.

PHP remote file inclusion vulnerability in contrib/yabbse/poc.php in phpopenchat before 3.0.2 allows remote attackers to execute arbitrary PHP code via the sourcedir parameter. NOTE: this issue was disputed by a third-party researcher who stated that the _REQUEST parameters were dynamically unset at the beginning of the file. Another researcher noted, and CVE agrees, that the unset PHP function can be bypassed (CVE-2006-3017). If this issue is due to a vulnerability in PHP, then it should be excluded from CVE
