AI Analysis

Impact

The User Management Engine in SAP NetWeaver Application Server for Java uses an outdated cryptographic algorithm to encrypt user mapping data, a weakness classified as improper encryption strength. This flaw can permit an attacker with elevated privileges, preferably those with local or otherwise high-level access, to partially reveal encrypted data. Consequently, confidentiality is at risk, while integrity and availability remain unaffected.

Affected Systems

This vulnerability affects the SAP NetWeaver Application Server for Java (NW AS Java) component known as User Mapping (UME). All versions of this product that rely on the specified old encryption algorithm are impacted; specific version information is not provided in the advisory.

Risk and Exploitability

The CVSS score of 3 indicates low severity, and the EPSS score of less than one percent suggests a very low probability of exploitation in the wild. The weakness is not listed in the CISA KEV catalog. Exploitation requires high-privileged access, making the attack vector likely internal or through compromised administrative accounts, rather than remote.

Remediation

No vendor fix or workaround currently provided.

OpenCVE Recommended Actions

  • Apply the SAP Note 3593356 updates that replace the obsolete encryption algorithm in NW AS Java UME.
  • Reconfigure UME to use a secure, modern encryption algorithm and ensure the configuration is enforced.
  • Reduce the privileges of accounts with access to UME, and monitor for unusual activity.
