Name of the Vulnerable Software and Affected Versions SilverStripe versions 2.4.0 through 2.4.5

Description The issue allows remote attackers to execute arbitrary code via a crafted cookie in a user comment submission, which is not properly handled when it is deserialized. This occurs in the code/sitefeatures/PageCommentInterface.php file.

Recommendations For SilverStripe versions 2.4.0 through 2.4.5, update to version 2.4.6 or later to resolve the issue. As a temporary workaround, consider restricting access to the PageCommentInterface.php file or disabling the comment submission feature until a patch is applied. Avoid using the affected PageCommentInterface.php file in the user comment submission process until the issue is resolved.
