PHP-Nuke 7.6 allows remote attackers to obtain sensitive information via direct requests to (1) the Surveys module with the file parameter set to comments or (2) 3D-Fantasy/theme.php, which leaks the full pathname of the web server in a PHP error message.

Multiple cross-site scripting (XSS) vulnerabilities in PHP-Nuke 6.x to 7.6 allow remote attackers to inject arbitrary web script or HTML via the (1) min parameter to the Search module, (2) the categories parameter to the FAQ module, or (3) the ltr parameter to the Encyclopedia module. NOTE: the bid parameter issue in banners.php is already an item in CVE-2005-1000.

HTTP Response Splitting vulnerability in the Surveys module in PHP-Nuke 7.6 allows remote attackers to spoof web content and poison web caches via hex-encoded CRLF ("%0d%0a") sequences in the forwarder parameter.

PHP-Nuke 7.6 and earlier allows remote attackers to obtain sensitive information via a direct request to (1) ipban.php, (2) db.php, (3) lang-norwegian.php, (4) lang-indonesian.php, (5) lang-greek.php, (6) a request to Web_Links with the portuguese language (lang-portuguese.php), (7) a request to Web_Links with the indonesian language (lang-indonesian.php), (8) a request to the survey module with the indonesian language (lang-indonesian.php), (9) a request to the Reviews module with the portuguese language, or (10) a request to the Journal module with the portuguese language, which reveal the path in an error message.

Multiple unspecified vulnerabilities in the WYSIWYG editor in PHP-Nuke before 7.9 Final have unknown impact and attack vectors.

Multiple SQL injection vulnerabilities in PHP-Nuke 7.8 allow remote attackers to modify SQL queries and execute arbitrary PHP code via (1) the username parameter in the Your Account page, (2) the url parameter in the Downloads module, and (3) the description parameter in the Web_Links module.

Multiple SQL injection vulnerabilities in the Search module in PHP-Nuke 7.8, and possibly other versions before 7.9 with patch 3.1, allows remote attackers to execute arbitrary SQL commands, as demonstrated via the query parameter in a stories type.

Interpretation conflict in includes/mainfile.php in PHP-Nuke 7.9 and later allows remote attackers to perform cross-site scripting (XSS) attacks by replacing the ">" in the tag with a "<", which bypasses the regular expressions that sanitize the data, but is automatically corrected by many web browsers. NOTE: it could be argued that this vulnerability is due to a design limitation of many web browsers; if so, then this should not be treated as a vulnerability in PHP-Nuke.
