VULNERABILITY DESCRIPTION:
Alt-N MDaemon is prone to an HTML/Javascript injection vulnerability because it fails to sanitize user-supplied input.
Attacker-supplied HTML and/or JavaScript code could run in the context of the affected site, potentially allowing the attacker to steal cookie-based authentication credentials and control how the site is rendered to the user; other attacks are also possible.
Alt-N MDaemon v13.0.3 & v12.5.6 were tested and found vulnerable; other versions may also be affected.
