At a glance
This record tracks a medium-severity Cross-Site Request Forgery (CSRF) vulnerability in the bbPress Login Register Links On Forum Topic Pages WordPress plugin, affecting versions <= 2.7.5. It carries a CVSS score of 5.4 (reachable over the network; low attack complexity). Exploitation requires no authentication. The issue is fixed in version 2.8.5; sites on affected versions should update now. Disclosed December 2019.
Vulnerability Overview
The bbPress Login Register Links On Forum Topic Pages plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 2.7.5. This is due to missing nonce validation on the bbPressCustomMenu(), tomas_bbPressLoginAdminBar(), tomas_bbPressCustomLoginRedirect(), and tomas_bbPressCustomLoginLinks() function. This makes it possible for unauthenticated attackers to modify the plugin's settings via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
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 privileges on the target site.
CWE-352: Cross-Site Request Forgery (CSRF)
bbPress Login Register Links On Forum Topic Pages <= 2.7.5 carries this weakness at bbPressCustomMenu(), and reaching it takes a caller who can reach the endpoint. Cross-site request forgery abuses the fact that browsers attach a victim's cookies to any request, so a state-changing action that only checks who you are, not whether you meant to act, can be triggered from another site.
An attacker who gets a logged-in user to load a crafted page can perform that action as them, with the impact scaling to whatever the victim's role is allowed to do. For bbPress Login Register Links On Forum Topic Pages the fix is 2.8.5: builds <= 2.7.5 are affected, anything from 2.8.5 onward is not.
Remediation
Update to version 2.8.5, or a newer patched version
