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
EMC NetWorker may potentially be vulnerable to an unauthenticated remote code execution vulnerability in the NetWorker Client execution service (nsrexecd) irrespective of any auth used.

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
How this class of weakness works · CWE-94

The application evaluates attacker-influenced input as code, handing them a way to run logic inside the process. Depending on the runtime this can escalate directly to remote code execution. Remediation means removing dynamic evaluation of untrusted input and replacing it with safe, data-driven alternatives.

Recommended fix Moderate confidence

Version higher than 19.8 (contact Dell support for exact fixed release number)

  1. 1. Review the Dell support article DSA-2023-041 for the specific patch/fixed version applicable to your installation
  2. 2. Obtain the fixed version of EMC NetWorker from Dell/EMC support
  3. 3. Schedule a maintenance window following your organization's change management procedures
  4. 4. Backup current NetWorker configuration and database
  5. 5. Deploy the upgraded NetWorker server and client components to the fixed version
  6. 6. Verify the nsrexecd service is running correctly after upgrade
  7. 7. Test critical backup and restore operations to confirm functionality
  8. 8. Monitor logs for any post-upgrade issues
