The HP Security Labs blog is pointing to a new database scanning tool called Scrubbr that can help check databases for possible stored cross-site scripting attacks. Scrubbr (download here) is described a Java program which connects to your database (MySQL 5+ MS SQL 2005+ and Oracle) directly and analyzes databases or specific tables looking for XSS strings. The strings are defined via an XML it comes with files from the OWASP AntiSamy project, but can be customized as needed.
