# kst-gpl## (C) Josh Zlatin-Amishav (josh at ramat dot cc)# GPLv2#desc["english"] = "Synopsis :The remote web server contains a PHP application that is prone tomultiple vulnerabilities. Description :The remote host is running gCards, a free electronic greeting cardsystem written in PHP. The installed version of gCards fails to sanitize user input to the'setLang' parameter in the 'inc/setLang.php' script which is called by'index.php'. An unauthenticated attacker may be able to exploit thisissue to read arbitrary local files or execute code from local filessubject to the permissions of the web server user id. There are also reportedly other flaws in the installed application,including a directory traversal issue that allows reading of localfiles as well as a SQL injection and a cross-site scripting issue.
