CVE-2023-29413
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 · uneditedA CWE-306: Missing Authentication for Critical Function vulnerability exists that could cause Denial-of-Service when accessed by an unauthenticated user on the Schneider UPS Monitor service.
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 analysisA sensitive function is reachable with no authentication at all, so anyone who finds the endpoint can use it. These are routinely discovered by automated scanning. The fix is to require and enforce authentication on every privileged path, with no exceptions left open.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scopedUpgrade to the fixed release version specified in SEVD-2023-101-04 (version numbers higher than 2.5-ga-01-22320 and 2.5-gs-01-22320)
- 1. Obtain the Schneider Electric security notice SEVD-2023-101-04 from https://download.schneider-electric.com/files?p_Doc_Ref=SEVD-2023-101-04&p_enDocType=Security+and+Safety+Notice&p_File_Name=SEVD-2023-101-04.pdf
- 2. Review the notice to identify the specific fixed version numbers for 'Apc Easy Ups Online Monitoring Software' and 'Easy Ups Online Monitoring Software'
- 3. Download the updated software version from Schneider Electric's official download portal
- 4. Before deploying, review release notes for any configuration or behavioral changes
- 5. Schedule a maintenance window and back up current configurations
- 6. Install the updated monitoring software following Schneider Electric's installation guide
- 7. Verify the service is running correctly and test that the authentication requirement is enforced
- 8. Confirm the vulnerability is mitigated by attempting the unauthenticated access (from an authorized test environment)
