SQL injection vulnerability in admin.php in the administration backend in Francisco Burzi PHP-Nuke 8.0 and earlier allows remote attackers to execute arbitrary SQL commands via the chng_uid parameter.

Multiple cross-site request forgery (CSRF) vulnerabilities in mainfile.php in Francisco Burzi PHP-Nuke 8.0 and earlier allow remote attackers to hijack the authentication of administrators for requests that (1) add user accounts or (2) grant the administrative privilege to a user account, related to a Referer check that uses a substring comparison.

Multiple cross-site scripting (XSS) vulnerabilities in Francisco Burzi PHP-Nuke 8.0 and earlier allow remote attackers to inject arbitrary web script or HTML via the (1) sender_name or (2) sender_email parameter in a Feedback action to modules.php.

SQL injection vulnerability in the Sections module in PHP-Nuke, probably before 8.0, allows remote attackers to execute arbitrary SQL commands via the artid parameter in a printpage action to modules.php.

SQL injection vulnerability in PHP-Nuke 6.9 and earlier, and possibly 7.x, allows remote attackers to inject arbitrary SQL code and gain sensitive information via (1) the category variable in the Search module or (2) the admin variable in the Web_Links module.

PHP-Nuke 7.3, and other products that use the PHP-Nuke codebase such as the Nuke Cops betaNC PHP-Nuke Bundle, OSCNukeLite 3.1, and OSC2Nuke 7x do not properly use the eregi() PHP function with $_SERVER['PHP_SELF'] to identify the calling script, which allows remote attackers to directly access scripts, obtain path information via a PHP error message, and possibly gain access, as demonstrated using an HTTP request that contains the "admin.php" string.

Cross-site scripting (XSS) vulnerability in the Your_Account module for PHP-Nuke 5.0 through 6.0 allows remote attackers to inject arbitrary web script or HTML via the user_avatar parameter.

Multiple SQL injection vulnerabilities in the Web_Links module for PHP-Nuke 5.x through 6.5 allows remote attackers to steal sensitive information via numeric fields, as demonstrated using (1) the viewlink function and cid parameter, or (2) index.php.

sql_layer.php in PHP-Nuke 5.4 and earlier does not restrict access to debugging features, which allows remote attackers to gain SQL query information by setting the sql_debug parameter to (1) index.php and (2) modules.php.

index.php for PHP-Nuke 5.4 and earlier allows remote attackers to determine the physical pathname of the web server when the file parameter is set to index.php, which triggers an error message that leaks the pathname.
