Macromedia ColdFusion MX Security Bypass Vulnerability

Monday, October 04 2004 @ 11:34 AM EDT

Eric Lackey has reported a vulnerability in ColdFusion MX, which can be exploited by malicious, authenticated users to bypass certain security restrictions.

The vulnerability is caused due to an error, which can be exploited to call restricted methods through an object of a specially crafted class written to the ColdFusion library directory.

Successful exploitation may e.g. disclose the administrative password, but requires permissions to create a Cold Fusion template on a server with CreateObject or cfobject tags enabled.

The vulnerability has been reported in version 6.1. Other versions may also be affected.

SOLUTION:
Grant only trusted users permissions to create templates on the ColdFusion MX server.

PROVIDED AND/OR DISCOVERED BY:
Eric Lackey
