  • →Traffic on ports 9543 may be TLS-encrypted; SSL/TLS inspection is required before applying byte-level detection signatures for this vulnerability. ↗
  • →The Nuclei PoC template uses a DNS-based OAST callback (interactsh) to confirm exploitation; network-level detection of outbound DNS queries from VMware Aria Operations for Logs hosts following inbound POST requests to /api/v2/internal/cluster/applyMembership may indicate successful exploitation. ↗
  • →The Nuclei PoC template checks for the string '"errorMessage":"Internal error' in the HTTP response body as a secondary confirmation of a vulnerable target. ↗
  • ·CVE-2023-20864 only affects VMware Aria Operations for Logs version 8.10.2; other versions are not vulnerable to this specific deserialization flaw (though they may be vulnerable to CVE-2023-20865). ↗
  • ·The expected Class Name embedded in the serialized object for each API endpoint may change in future versions of the software, requiring detection signature updates. ↗
