Title: backupDB() v1.2.7a (onlyDB) Remote XSS Vulnerability
Advisory ID: ZSL-2012-5089
Type: Remote
Impact: Cross-Site Scripting
Risk: (2/5)
Release Date: 16.05.2012

Summary

backupDB() is a PHP script that backs up MySQL tables and databases to a file (uncompressed, gzip, bzip2) for easy daily backup.

Description

backupDB is prone to a cross-site scripting vulnerability. This issue is due to a failure in the application to properly sanitize user-supplied input to the 'onlyDB' parameter of the 'backupDB.php' script. Attackers can exploit this weakness to execute arbitrary HTML and script code in a user's browser session.
