CVE-2019-0344
RCE in Sap Commerce Cloud 1808 … 6.7
Raw vector
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:HCVSS and EPSS are reproduced from their sources (NVD, FIRST EPSS). Risk Priority is our own derived reading, not an NVD score.
Summary
CVE-2019-0344 is a critical-severity Deserialization of Untrusted Data (CWE-502) vulnerability in Sap Commerce Cloud. Its CVSS base score is 9.8 (Critical).
Operationally, exploitation aligns with the MITRE ATT&CK technique Junk Data (T1001.001); ranked in the top 6% of CVEs by exploit likelihood; CISA has added it to the Known Exploited Vulnerabilities catalog.
Deeper analysis AI-assisted summary
Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2019-0344 is an unsafe deserialization vulnerability in the virtualjdbc extension of SAP Commerce Cloud (formerly Hybris), affecting versions 6.4, 6.5, 6.6, 6.7, 1808, 1811, and 1905. The flaw, tracked under CWE-502, allows untrusted data to be deserialized without proper validation, enabling code injection that executes with the privileges of the Hybris user account. It carries a CVSS 3.1 base score of 9.8, reflecting network-accessible exploitation with low attack complexity and no required credentials or user interaction.
An unauthenticated remote attacker can send a crafted serialized object to the vulnerable extension and achieve arbitrary code execution on the target system. Successful exploitation grants the attacker the ability to run commands, access or modify data, and potentially pivot within the affected SAP environment under Hybris user rights.
SAP security notes 2786035 and associated wiki documentation provide remediation guidance, including patches that address the deserialization issue in supported releases. The vulnerability appears in the CISA Known Exploited Vulnerabilities catalog, confirming observed real-world exploitation activity.

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Penetration testing supplies malicious serialized objects, detecting unsafe deserialization and supporting corrective actions.
Evaluation of untrusted data handling (deserialization testing) reveals unsafe processing, which the required remediation process addresses.
Untrusted serialized data can be deserialized and observed inside the chamber, blocking gadget-chain exploitation outside the sandbox.
Validates or rejects untrusted serialized data before deserialization occurs.
Identifies and blocks malicious code introduced through deserialization of untrusted data at system boundaries.
Integrity verification of serialized information can detect tampering before deserialization occurs.
Provenance of associated data allows detection of untrusted sources before deserialization or processing occurs.
