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.

The CAPTCHA implementation as used in (1) Francisco Burzi PHP-Nuke 7.0 and 8.1, (2) my123tkShop e-Commerce-Suite (aka 123tkShop) 0.9.1, (3) phpMyBitTorrent 1.2.2, (4) TorrentFlux 2.3, (5) e107 0.7.11, (6) WebZE 0.5.9, (7) Open Media Collectors Database (aka OpenDb) 1.5.0b4, and (8) Labgab 1.1 uses a code_bg.jpg background image and the PHP ImageString function in a way that produces an insufficient number of different images, which allows remote attackers to pass the CAPTCHA test via an automated attack using a table of all possible image checksums and their corresponding digit strings.

Multiple cross-site scripting (XSS) vulnerabilities in the Search Module in PHP-Nuke allow remote attackers to inject arbitrary web script or HTML via a trailing "<" instead of a ">" in (1) the onerror attribute of an IMG element, (2) the onload attribute of an IFRAME element, or (3) redirect users to other sites via the META tag.
