id: CVE-2018-3810
info:
name: Oturia WordPress Smart Google Code Inserter <3.5 - Authentication Bypass
author: princechaddha
severity: critical
description: Oturia Smart Google Code Inserter plugin before 3.5 for WordPress allows unauthenticated attackers to insert arbitrary JavaScript or HTML code (via the sgcgoogleanalytic parameter) that runs on all pages served by WordPress. The saveGoogleCode() function in smartgooglecode.php does not check if the current request is made by an authorized user, thus allowing any unauthenticated user to successfully update the inserted code.
impact: |
An attacker can bypass authentication and gain unauthorized access to the affected WordPress site.
remediation: |
Update to the latest version of the Oturia WordPress Smart Google Code Inserter plugin (3.5 or higher) to fix the authentication bypass vulnerability.
