Horde IMP Webmail 'fetchmailprefs.php' HTML Injection Vulnerability

Summary
Horde IMP Webmail is prone to an HTML-injection vulnerability because it fails to sufficiently sanitize user-supplied data before it is used in dynamic content. Attacker-supplied HTML or JavaScript code could run in the context of the affected site, potentially allowing the attacker to steal cookie- based authentication credentials and to control how the site is rendered to the user other attacks are also possible. Horde IMP 4.3.7 is affected other versions may also be vulnerable.
