Title: Powerboards Unauthorized Post Deletion Vulnerability
Severity: HIGH
Description:
Powerboards is a bulletin board application developed in PHP.
By design, a post may be deleted by either the author of that post, or an administrator of the Powerboards system. Reportedly, there are no real access restrictions on this ability. Rather, unauthorized parties are not provided with a link to the delete function.
As a result, a knowledgeable attacker may artifically construct a URL which will delete an arbitrary post within the system. It is not known if a valid user account on the Powerboards system is required. However, the issues discussed in BID 4468 may reduce the effectiveness of any such restriction.
Reportedly, a URL of the following form will result in post deletion:
/delpost.php?cat=3&fid=4&pid=5
Affected Products:
- Powerboards Powerboards 2.2.0b
