SQL injection vulnerability in the Docum module in PHP-Nuke allows remote attackers to execute arbitrary SQL commands via the artid parameter in a viewarticle operation.

The CAPTCHA implementation in (1) Pligg 9.9.5 and possibly (2) Francisco Burzi PHP-Nuke 8.1 provides a critical random number (the ts_random value) within the URL in the SRC attribute of an IMG element, which allows remote attackers to pass the CAPTCHA test via a calculation that combines this value with the current date and the HTTP User-Agent string.

Unrestricted file upload vulnerability in the DownloadsPlus module in PHP-Nuke allows remote attackers to execute arbitrary code by uploading a file with (1) .htm, (2) .html, or (3) .txt extensions, then accessing it via a direct request to the file. NOTE: the provenance of this information is unknown; the details are obtained solely from third party information. NOTE: it is unclear how allowing the upload of .html or .txt files supports arbitrary code execution; this might be legitimate functionality.

Cross-site scripting (XSS) vulnerability in the League module for PHP-Nuke, possibly 2.4, allows remote attackers to inject arbitrary web script or HTML via the tid parameter in a team action to modules.php.

SQL injection vulnerability in modules.php in the Sectionsnew module for PHP-Nuke allows remote attackers to execute arbitrary SQL commands via the artid parameter in a printpage action.

SQL injection vulnerability in index.php in the Recipes module 1.3, 1.4, and possibly other versions for PHP-Nuke allows remote attackers to execute arbitrary SQL commands via the recipeid parameter.
