Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
SQL injection vulnerability in the UDDI server in SAP NetWeaver J2EE Engine 7.40 allows remote attackers to execute arbitrary SQL commands via unspecified vectors, aka SAP Security Note 2101079.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · moderate confidence

SQL injection vulnerability in the UDDI server component of SAP NetWeaver J2EE Engine 7.40 allows remote unauthenticated attackers to execute arbitrary SQL commands via unspecified input vectors. The vulnerability stems from improper input validation in the UDDI service, enabling attackers to manipulate SQL queries.

MitigationApply SAP Security Note 2101079 which provides the patch for this vulnerability. Prior to deployment, inventory all SAP NetWeaver 7.40 systems running the J2EE engine, test the patch in a non-production environment, and schedule maintenance windows as UDDI services may require restart.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Verify SAP NetWeaver AS Java version
    Check the installed version of SAP NetWeaver Application Server Java by inspecting the SAP system information or using the SAP Management Console. Look for version 7.40 specifically.
    Affected if The installed version is exactly 7.40 (matches the affected version range)
  2. Confirm UDDI server component is enabled
    Check the SAP NetWeaver configuration to determine whether the UDDI (Universal Description, Discovery and Integration) server component is enabled and running. This can be verified through the SAP Administrator or through the SAP NetWeaver Administrator (NWA) interface.
    Affected if The UDDI server component is enabled and operational in the SAP environment
  3. Verify UDDI server network accessibility
    Determine if the UDDI server is exposed to network access by reviewing firewall rules, SAP Gateway configurations, and HTTP service bindings. Check if the UDDI server ports are listening on accessible network interfaces.
    Affected if The UDDI server is reachable over the network from untrusted sources
  4. Review UDDI server logs for suspicious activity
    Examine SAP NetWeaver UDDI server logs for unusual SQL-like error messages, unexpected query patterns, or evidence of SQL injection attempts.
    Affected if Logs contain SQL errors, malformed queries, or indicators of injection attempts

If the environment runs SAP NetWeaver AS Java 7.40 with the UDDI server enabled and network-accessible, it is potentially affected by this SQL injection vulnerability and should be evaluated against SAP Security Note 2101079.
