WordPress vulnerability analysis and mitigation

Overview

The Beautiful Cookie Consent Banner WordPress plugin (versions up to 2.10.1) contains a Stored Cross-Site Scripting (XSS) vulnerability identified as CVE-2023-3388. The vulnerability was discovered in June 2023 and affects the 'nscbarcontent_href' parameter due to insufficient input sanitization and output escaping (NVD).

Technical details

The vulnerability is classified as a Stored Cross-Site Scripting (CWE-79) issue with a CVSS v3.1 base score of 6.1 MEDIUM (NIST) to 7.2 HIGH (Wordfence). The vulnerability exists due to improper neutralization of input during web page generation, specifically in the 'nscbarcontent_href' parameter (NVD, WPScan).

Impact

The vulnerability allows unauthenticated attackers to inject arbitrary web scripts into pages that will execute whenever a user accesses an injected page. This can lead to potential theft of sensitive information, session hijacking, or other malicious actions performed in the context of the affected users (NVD).

Mitigation and workarounds

A partial patch was released in version 2.10.1, and the vulnerability was fully patched in version 2.10.2. Website administrators are strongly advised to update to version 2.10.2 or later to protect against this vulnerability (NVD).
