CVE: Awaiting assignment
CVSS: 5.8 (Medium; AV:N/AC:M/Au:N/C:P/I:P/A:N)
Reflected XSS in GD bbPress Attachments allows an attacker to do almost anything an admin can
This plugin outputs the value of $_GET[‘tab’] without escaping (see forms/panels.php lines 3 and 39). An attacker could easily construct an URL which performs virtually any action an admin is able to perform, including creating/deleting users/posts, injecting malicious HTML into user-facing pages, or editing PHP files (if that feature hasn’t been disabled).
Proof of concept
Visit the following URL in a browser with no reflected XSS protection (i.e. Firefox or older versions of IE):
Upgrade to version 2.3 or later
