FrSIRT has posted the following information about a new vulnerability in WordPress 2.02 and previous versions:
Advisory ID : FrSIRT/ADV-2006-1992
CVE ID : GENERIC-MAP-NOMATCH
Rated as : High Risk
Remotely Exploitable : Yes
Locally Exploitable : Yes
Release Date : 2006-05-26
A vulnerability has been identified in WordPress, which may be exploited by attackers to compromise a vulnerable web server. This flaw is due to input validation errors in the “wp-admin/profile.php” script that does not validate certain parameters before being written to PHP scripts in the “wp-content/cache/userlogins/” and “wp-content/cache/users/” directories, which could be exploited by malicious users to inject and execute arbitrary PHP code with the privileges of the web server.
Note : An input validation error in the “vars.php” script when handling the “PC_REMOTE_ADDR” HTTP header could be exploited by attackers to spoof their IP addresses.
WordPress version 2.0.2 and prior
The FrSIRT is not aware of any official supplied patch for this issue.
