Senserva AI Opinion for CVE-2019-0344

SAP Commerce Cloud, the platform formerly known as Hybris, carries a Critical Severity deserialization flaw in its mediaconversion and virtualjdbc extensions that allows code injection. The 7% EPSS figure looks modest, but CISA added it to the KEV catalog in September 2024, so real attackers are using it against the e-commerce platforms that run on this software. Organizations hosting storefronts on older Commerce Cloud builds are the exposed population.

Do this: Inventory your SAP Commerce Cloud instances today and apply the SAP fix for the mediaconversion and virtualjdbc extensions on any unpatched system.
