Vulnerability Overview

This is due to missing or incorrect nonce validation on the sf_clone_slider, sf_save_slider, and sf_remove_slider functions. This makes it possible for unauthenticated attackers to clone, save and/or remove sliders via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.

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 confidentiality, integrity, availability — full site compromise territory.
CWE-352: Cross-Site Request Forgery (CSRF)
Reaching this weakness in Slider, Image Slider & Carousel by Slider Factory < 1.3.2 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 Slider, Image Slider & Carousel by Slider Factory the fix is 1.3.2: builds < 1.3.2 are affected, anything from 1.3.2 onward is not.
Remediation
Update to version 1.3.2, or a newer patched version
