Horde NLS.php Language Selection new_lang Parameter XSS

2007-03-1600:00:00

www.tenable.com

The version of Horde installed on the remote host fails to sanitize input to the ‘new_lang’ parameter before using it in the ‘framework/NLS/NLS.php’ script to generate dynamic content. An unauthenticated, remote attacker may be able to leverage this issue to inject arbitrary HTML or script code into a user’s browser to be executed within the security context of the affected site.
