At a glance
CVE-2021-25098 is a medium-severity Cross-Site Request Forgery (CSRF) vulnerability in the Pricing Table WordPress Plugin WordPress plugin, affecting versions <= 3.1.2. It carries a CVSS score of 6.5 (reachable over the network; low attack complexity; high integrity impact). Exploitation requires no authentication. The issue is fixed in version 3.1.3; sites on affected versions should update now. Disclosed February 2022, reported by Krzysztof Zając.
Vulnerability Overview
The Pricing Tables WordPress Plugin WordPress plugin before 3.1.3 does not verify the CSRF nonce when removing posts, allowing attackers to make a logged in admin remove arbitrary posts from the blog via a CSRF attack, which will be put in the trash
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. A successful exploit has high impact on integrity.
CWE-352: Cross-Site Request Forgery (CSRF)
Reaching this weakness in Pricing Table WordPress Plugin <= 3.1.2 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 Pricing Table WordPress Plugin the fix is 3.1.3: builds <= 3.1.2 are affected, anything from 3.1.3 onward is not.
Remediation
Update to version 3.1.3, or a newer patched version
How does WordSec protect against this?
The attempt arrives as an ordinary request to Pricing Table WordPress Plugin: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Pricing Table WordPress Plugin 3.1.3 closes this, and updating the plugin is the step that ends it.
