There is a SQL Injection vulnerability in PHP-Nuke 8.3.3 in the User Registration section, leading to remote code execution. This occurs because the U.S. state is not validated to be two letters, and the OrderBy field is not validated to be one of LASTNAME, CITY, or STATE.

Francisco Burzi PHP-Nuke 8.0 allows remote attackers to obtain sensitive information via a direct request to a .php file, which reveals the installation path in an error message, as demonstrated by themes/Odyssey/theme.php and certain other files.

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) sendername or (2) senderemail parameter in a Feedback action to modules.php.

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.

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.

SQL injection vulnerability in the MyeGallery module for PHP-Nuke allows remote attackers to execute arbitrary SQL commands via the gid parameter in a showgall action to modules.php. NOTE: this issue was disclosed by an unreliable researcher, so the details might be incorrect.

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 the Sarkilar module for PHP-Nuke allows remote attackers to execute arbitrary SQL commands via the id parameter in a showcontent 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.

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 the Gallery module 1.3 for PHP-Nuke allows remote attackers to execute arbitrary SQL commands via the aid parameter in a showalbum action to index.php. NOTE: some of these details are obtained from third party information. NOTE: this issue was disclosed by an unreliable researcher, so it might be incorrect.

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.

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 codebg.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.

SQL injection vulnerability in the Johannes Hass gaestebuch 2.2 module for PHP-Nuke allows remote attackers to execute arbitrary SQL commands via the id parameter in an edit action to modules.php.

SQL injection vulnerability in the Sudirman Angriawan NukeC30 3.0 module for PHP-Nuke allows remote attackers to execute arbitrary SQL commands via the idcatg parameter in a ViewCatg action to modules.php.
