At a glance
CVE-2023-25703 is a medium-severity Cross-Site Request Forgery (CSRF) vulnerability in the Meta Slider and Carousel with Lightbox WordPress plugin, affecting versions <= 1.6.2. 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 1.7; sites on affected versions should update now. Disclosed February 2023, reported by Cat.
Vulnerability Overview
The Meta Slider and Carousel with Lightbox plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 1.6.2. This is due to missing or incorrect nonce validation on the 'wp_igsp_get_attachment_edit_form' and 'wp_igsp_save_attachment_data' functions. This makes it possible for unauthenticated attackers to modify attachment data 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)
Meta Slider and Carousel with Lightbox <= 1.6.2 carries this weakness at wp_igsp_get_attachment_edit_form, 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 Meta Slider and Carousel with Lightbox the fix is 1.7: builds <= 1.6.2 are affected, anything from 1.7 onward is not.
Remediation
Update to version 1.7, or a newer patched version
How does WordSec protect against this?
The attempt arrives as an ordinary request to Meta Slider and Carousel with Lightbox: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Meta Slider and Carousel with Lightbox 1.7 closes this, and updating the plugin is the step that ends it.
