CVE-2023-5821
WordPress vulnerability analysis and mitigation

Overview

The Thumbnail carousel slider plugin for WordPress version 1.0 contains a Cross-Site Request Forgery (CSRF) vulnerability. The vulnerability exists due to missing nonce validation in the deleteselected function, which was discovered and reported on October 26, 2023 (NVD).

Technical details

The vulnerability has been assigned a CVSS v3.1 base score of 6.5 (Medium) with the vector string CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:H/A:N. A lower CVSS score of 4.3 (Medium) was also assigned by Wordfence. The vulnerability stems from the absence of proper CSRF protection mechanisms in the form of nonce validation within the deleteselected function (NVD).

Impact

The vulnerability allows unauthenticated attackers to delete sliders in bulk through forged requests. The attack can only be successful if an attacker can trick a site administrator into performing specific actions, such as clicking on a malicious link (NVD).

Mitigation and workarounds

Users should update to a version newer than 1.0 of the Thumbnail carousel slider plugin. The vulnerability has been addressed in subsequent releases through the implementation of proper nonce validation (WordPress Plugin).
