Disclosed December 2019, reported by nomnom.
Vulnerability Overview
The BuddyPress plugin for WordPress is vulnerable to Denial of Service in versions up to, and including, 5.1.0. This makes it possible for authenticated attackers to remove another user’s avatar and/or remove any empty folder.
Technical Analysis
The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no interaction from a victim user.
CWE-400: Uncontrolled Resource Consumption
Reaching this weakness in BuddyPress <= 5.1.0 takes a caller who can reach the endpoint. Uncontrolled resource consumption means a request can make the server do an amount of work it never bounds, because the size or repetition of the job is taken from the request rather than capped by the code.
A single caller can hold PHP workers, database connections or disk open long enough to slow the site for everyone, without needing any account or any other flaw. For BuddyPress the fix is 5.1.1: builds <= 5.1.0 are affected, anything from 5.1.1 onward is not.
Remediation
Update to version 5.1.1, or a newer patched version
How does WordSec protect against this?
The attempt arrives as an ordinary request to BuddyPress: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: BuddyPress 5.1.1 closes this, and updating the plugin is the step that ends it.
