Quixplorer <=2.4.1 is vulnerable to reflected cross-site scripting (XSS) caused by improper validation of user supplied input. A remote attacker could exploit this vulnerability using a specially crafted URL to execute a script in a victim's Web browser within the security context of the hosting Web site, once the URL is clicked. An attacker could use this vulnerability to steal the victim's cookie-based authentication credentials.

Multiple cross-site scripting (XSS) vulnerabilities in QuiXplorer before 2.5.5 allow remote attackers to inject arbitrary web script or HTML via the (1) dir, (2) item, (3) order, (4) searchitem, (5) selitems[], or (6) srt parameter to index.php or (7) the QUERY_STRING to index.php.

Directory traversal vulnerability in the zip download functionality in QuiXplorer before 2.5.5 allows remote attackers to read arbitrary files via a .. (dot dot) in the selitems[] parameter in a download_selected action to index.php.

Unrestricted file upload vulnerability in QuiXplorer 2.3 and earlier allows remote attackers to execute arbitrary code by uploading a file with an executable extension using the upload action to index.php, then accessing it via a direct request to the file in an unspecified directory.

Cross-site scripting (XSS) vulnerability in the Typo3 Quixplorer (t3quixplorer) extension before 1.7.1 for TYPO3 allows remote attackers to inject arbitrary web script or HTML via unspecified vectors.

Directory traversal vulnerability in .include/init.php (aka admin/_include/init.php) in QuiXplorer 2.3.2 and earlier, as used in TinyWebGallery (TWG) 1.7.6 and earlier, allows remote attackers to include and execute arbitrary local files via a .. (dot dot) in the lang parameter to admin/index.php.
