CVE-2023-45606
At a glance
CVE-2023-45606 is a medium-severity Cross-Site Request Forgery (CSRF) vulnerability in the Lasso Lite WordPress plugin, affecting versions <= 120. 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 121; sites on affected versions should update now. Disclosed October 2023, reported by Kévin Mosbahi (Mika).
Vulnerability Overview
The Simple URLs plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 120. This is due to missing or incorrect nonce validation on multiple AJAX functions. This makes it possible for unauthenticated attackers to perform unauthorized actions (e.g., delete arbitrary posts, add new links, save plugin settings, etc.) 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)
Reaching this weakness in Lasso Lite <= 120 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 Lasso Lite the fix is 121: builds <= 120 are affected, anything from 121 onward is not.
Remediation
Update to version 121, or a newer patched version
How does WordSec protect against this?
The attempt arrives as an ordinary request to Lasso Lite: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Lasso Lite 121 closes this, and updating the plugin is the step that ends it.
