Overview
Allaire Forums does not verify user information submitted in hidden fields on a web form, allowing attackers to impersonate other users.
Description
Allaire Forums is a web-based bulletin board system that runs on Cold Fusion. When a user wishes to post a message, Allaire Forums dynamically generates a web form including the user's name and email address in hidden fields. Attackers may easily change these fields to specify a different user, and Alliare Forums does not check the submission to authenticate the user. Therefore, attackers may post messages to the bulletin board signed by a different user's name and email address. |
Impact
Malicious users of Allaire Forums may impersonate other users. |
Solution
The CERT/CC is currently unaware of a practical solution to this problem. |
