A vulnerability in WordPress 2.8.3 which allows anyone to lock an admin out of his or her account by resetting the password has been reported.
“The bug … is trivial to exploit remotely using nothing more than a web browser and a specially manipulated link. Typically, requests to reset a password are handled using a registered email address. Using the special URL, the old password is removed and a new one generated in its place with no confirmation required.”
The exploit doesn’t enable take-over of the blog but it does allow a prankster to lock an admin out of their blog by resetting the password.
An alert on the Full Disclosure mailing list detailed the vulnerability, and WordPress quickly rolled out version 2.8.4 to address the issue.
