SquirrelMail pages can be embedded, enabling clickjacking

CVE-2010-4554 · published 15 years ago
Summary

The SquirrelMail webmail interface can be loaded inside another website’s frame, which lets attackers trick users into clicking hidden buttons or links. This could lead to unauthorized actions being performed in the victim’s email account. Update to a newer version of SquirrelMail or configure the server to send headers that block framing.
