NVD · unedited
Cache Management Service in SAP NetWeaver Application Server for Java - version 7.50, does not perform any authentication checks for functionalities that require user identity

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

The Cache Management Service in SAP NetWeaver Application Server for Java v7.50 lacks authentication checks on functions that should require user identity. This allows unauthenticated remote attackers to access cache management functionality that should be restricted to authenticated users, potentially exposing or manipulating cached data.

MitigationApply the relevant SAP security patch for CVE-2023-26460. Until patched, restrict network access to the Cache Management Service through network segmentation or firewall rules to limit exposure to untrusted networks.

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. Identify SAP NetWeaver AS for Java version
    Execute the SAP J2EE engine version command: using SAP Management Console or execute 'j2eeadmin -sh Version' or check via SAP MMC snap-in under 'J2EE Engine > System > Information'. Look for the version string in the output.
    Affected if The installed version is exactly 7.50 (the only affected version per this CVE).
  2. Locate the Cache Management Service port
    Check SAP J2EE cluster configuration files: review the 'cluster.xml' or 'server.xml' files in the usr/sap/<SID>/<instance>/j2ee/cluster/config directory. Search for entries containing 'Cache' or 'CacheManager' service definitions and note the associated port number.
    Affected if The Cache Management Service is defined and exposed on a network port in the configuration.
  3. Verify service network accessibility
    From a remote system or using netstat on the SAP host, check if the Cache Management Service port (typically found in step 2) is listening on an external network interface. Use command: 'netstat -an | grep <port>' or 'telnet <host> <port>' from an untrusted network segment.
    Affected if The service port is bound to 0.0.0.0 or an external IP address (not bound to 127.0.0.1 only).
  4. Confirm unauthenticated access exposure
    Attempt a curl or HTTP request to the Cache Management Service endpoint: 'http://<hostname>:<port>/cachemanager' or similar cache management URL without providing any SAP authentication credentials. Check if the application returns cache management functionality or data instead of redirecting to a login page.
    Affected if The service responds with cache management interface or data without requiring authentication.

You are affected if you run SAP NetWeaver Application Server for Java version 7.50 AND the Cache Management Service port is network-accessible AND the service responds to unauthenticated requests.
