# CVE-2019-0344: SAP Commerce Cloud Deserialization of Untrusted Data Vulnerability

**Signal:** Exploited: patch now if you run it. CISA has confirmed exploitation in the wild. (Computed from CISA KEV, EPSS and CVSS; not an editorial verdict.)

## Should you act?

- Yes, if you run SAP Commerce Cloud. CISA added this CVE to its Known Exploited Vulnerabilities catalog on 2024-09-30, which means there is reliable evidence of exploitation in the wild. US federal agencies must remediate by 2024-10-21 ; treat that as the outer limit, not the target.
- EPSS 7.1% , percentile 94: FIRST’s model estimates a 7.1% chance of exploitation activity in the next 30 days, higher than 94% of all scored CVEs (elevated). EPSS is a probability, not a verdict.
- Remotely reachable with no login and no user interaction. If the vulnerable service is exposed to the internet, prioritize it.

## What it is

Due to unsafe deserialization used in SAP Commerce Cloud (virtualjdbc extension), versions 6.4, 6.5, 6.6, 6.7, 1808, 1811, 1905, it is possible to execute arbitrary code on a target machine with 'Hybris' user rights, resulting in Code Injection.

## Affected products (CVE record)

- SAP SE SAP Commerce Cloud (virtualjdbc extension): < 6.4, < 6.5, < 6.6, < 6.7, < 1808, < 1811, < 1905

## Exploitation

- CISA KEV: added 2024-09-30; federal due date 2024-10-21. Known ransomware use: Unknown.
- CISA required action: Apply mitigations per vendor instructions or discontinue use of the product if mitigations are unavailable.
- CISA SSVC assessment: exploitation active , automatable yes , technical impact total .
- FIRST EPSS (model of 2026-10-21): 7.08% probability of exploitation activity in the next 30 days; percentile 94.
