CVE-2018-3810

Name of the Vulnerable Software and Affected Versions Oturia Smart Google Code Inserter plugin versions prior to 3.5

Description The issue allows unauthenticated attackers to insert arbitrary JavaScript or HTML code that runs on all pages served by WordPress. This is achieved via the sgcgoogleanalytic parameter. 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.

Recommendations For Oturia Smart Google Code Inserter plugin versions prior to 3.5, update to version 3.5 or later to resolve the issue. As a temporary workaround, consider disabling the saveGoogleCode() function in smartgooglecode.php until a patch is available. Restrict access to the sgcgoogleanalytic parameter to minimize the risk of exploitation.
