# Due to unsafe deserialization used in SAP Commerce Cloud (virtualjdbc extension), versions 6.4, 6.5, 6.6, 6.7, 1808,…

SAP Commerce Cloud (formerly Hybris) has a deserialization flaw in its mediaconversion and virtualjdbc extensions. An attacker who can send crafted serialized data can inject code that runs on the server.

_Summary, check and fix written by a model from the sources; labelled as such._

## Affected

- vendor:SAP Commerce Cloud affected ? fixed ?
- vendor:sap commerce cloud affected = 6.4 fixed ?
- vendor:sap commerce cloud affected = 6.5 fixed ?
- vendor:sap commerce cloud affected = 6.6 fixed ?
- vendor:sap commerce cloud affected = 6.7 fixed ?
- vendor:sap commerce cloud affected = 1808 fixed ?
- vendor:sap commerce cloud affected = 1811 fixed ?
- vendor:sap commerce cloud affected = 1905 fixed ?

## Fix

Apply the mitigations from the vendor (SAP) instructions, or stop using the affected product if no mitigation is available.

## From the sources

SAP Commerce Cloud (formerly known as Hybris) contains a deserialization of untrusted data vulnerability within the mediaconversion and virtualjdbc extension that allows for code injection.

CISA required action: Apply mitigations per vendor instructions or discontinue use of the product if mitigations are unavailable.
