At a glance
CVE-2021-24730 is a medium-severity Cross-Site Request Forgery (CSRF) vulnerability in the Logo Showcase WordPress plugin, affecting versions < 1.2.5. It carries a CVSS score of 4.3 (reachable over the network; low attack complexity). The issue is fixed in version 1.2.5; sites on affected versions should update now. Disclosed October 2021, reported by apple502j.
Vulnerability Overview
The Logo Showcase with Slick Slider WordPress plugin before 1.2.5 does not have CSRF and authorisation checks in the lswss_save_attachment_data AJAX action, allowing any authenticated users, such as Subscriber, to change title, description, alt text, and URL of arbitrary uploaded media.
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-352: Cross-Site Request Forgery (CSRF)
Reaching this weakness in Logo Showcase < 1.2.5 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 Logo Showcase the fix is 1.2.5: builds < 1.2.5 are affected, anything from 1.2.5 onward is not.
Remediation
Update to version 1.2.5, or a newer patched version
How does WordSec protect against this?
The attempt arrives as an ordinary request to Logo Showcase: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Logo Showcase 1.2.5 closes this, and updating the plugin is the step that ends it.
