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.
Multiple cross-site scripting (XSS) vulnerabilities in the RMSOFT Downloads Plus (rmdp) module 1.5 and 1.7 for Xoops allow remote attackers to inject arbitrary web script or HTML via the (1) key parameter to search.php and the (2) id parameter to down.php.
