APP.EXPLOIT.CVE-2023-49070
  • The vulnerable unauthenticated endpoint is /webtools/control/xmlrpc — monitor HTTP requests (especially POST with XML body) to this path on Apache OFBiz instances as a primary detection point.
  • Active exploitation attempts use PoC payloads that force vulnerable servers to make outbound DNS/HTTP connections to oast.online — monitor for unexpected outbound connections to this domain from OFBiz servers.
  • Exploitation leverages Java deserialization via the ROME gadget chain (older versions) or CommonsBeanutils1 gadget chain (18.12.x with auth bypass). Detect serialized Java payloads in HTTP POST bodies to /webtools/control/xmlrpc.
  • Nuclei template for CVE-2023-49070 uses a DNS interaction check — look for the faultString keyword in HTTP responses as a secondary indicator of a vulnerable OFBiz instance.
  • Attackers scanning for CVE-2023-49070 are specifically interested in identifying vulnerable Confluence servers — correlate OFBiz exploitation attempts with subsequent Confluence-targeted activity.
  • Post-exploitation: look for the OFBiz Derby database credential file at /opt/ofbiz/runtime/data/derby/ofbiz/seg0/ containing hashed passwords in the format $SHA$<salt>$<base64hash>.
  • ·The Metasploit module switches gadget chains depending on version: ROME for pre-17.12.01, CommonsBeanutils1 for 18.12.x with CVE-2023-51467 auth bypass — detection rules must account for both payload types.
  • ·All versions 18.12.9 and below are impacted by CVE-2023-49070; all versions 18.12.10 and below are additionally impacted by CVE-2023-51467 — version-based blocking must use 18.12.11 as the minimum safe version for the combined risk.
