Username information leak on wp-login.php

Reported by: jimp79's profile jimp79 Owned by:

Severity: major Version:
Component: Administration Keywords: security
Focuses: Cc:


The wp-login.php leaks valid usernames due to the fact that it gives different error messages if the entered user exists or not.

If the username exists the error message is: ERROR: Incorrect password.
If the username does not exist then the error message is: ERROR: Invalid username.

This vulnerability could be leveraged by an attacker to assist in performing a brute force or dictionary attack against th login form.
