MemHT Portal "User-Agent" HTTP Header HTML Injection Vulnerability

MemHT Portal is prone to an HTML-injection vulnerability because it fails to properly sanitize user-supplied input.

Successful exploits will allow attacker-supplied HTML and script code to run in the context of the affected browser, potentially allowing the attacker to steal cookie-based authentication credentials or to control how the site is rendered to the user. Other attacks are also possible.

The issue affects MemHT Portal 4.0.1; other versions may also be vulnerable.
