WordPress vulnerability analysis and mitigation
Overview
CVE-2023-4520 affects the FV Flowplayer Video Player plugin for WordPress in versions up to and including 7.5.37.7212. The vulnerability was discovered and disclosed in August 2023, impacting the plugin's handling of the 'fvplayeruservideo' parameter (NVD).
Technical details
The vulnerability consists of two main issues: a Stored Cross-Site Scripting (XSS) vulnerability via the 'fvplayeruservideo' parameter saved through the 'save' function hooked via init, and an Arbitrary Usermeta Update vulnerability via the same 'save' function. The severity is rated as MEDIUM with a CVSS v3.1 base score of 6.1 (NVD).
Impact
The vulnerability allows unauthenticated attackers to inject arbitrary web scripts that execute when users access an affected page. Additionally, attackers can update user meta values arbitrarily, though these values are restricted to string data types (NVD).
Mitigation and workarounds
Users should update their FV Flowplayer Video Player plugin to a version newer than 7.5.37.7212. The vulnerability has been patched in subsequent releases (Wordpress Plugin).
