Detection & IOCsextracted from sources · hover to see the quote

  • CVE-2026-21992 is exploitable unauthenticated over HTTP (no authentication, no user interaction required) targeting Oracle Identity Manager REST WebServices and Oracle Web Services Manager Web Services Security components — monitor for anomalous unauthenticated HTTP requests to these endpoints
  • Oracle released an out-of-band (emergency) patch for CVE-2026-21992, indicating high urgency; treat unpatched Oracle Identity Manager and Oracle Web Services Manager instances (versions 12.2.1.4.0 and 14.1.2.1.0) as actively at risk
  • Possible in-the-wild exploitation reported; treat any unexpected process spawning or outbound connections from Oracle Identity Manager or Web Services Manager processes as high-priority indicators
  • A related pre-authenticated RCE flaw in the same Oracle Identity Manager component (CVE-2025-61757) was confirmed exploited in the wild and added to CISA KEV in November 2025 — treat CVE-2026-21992 exploitation TTPs as likely similar
  • Oracle declined to confirm exploitation status to press, suggesting possible active exploitation being investigated; prioritize network-level detection of unauthenticated HTTP RCE attempts against Oracle Identity Manager REST and Web Services Manager endpoints
  • ·Patches released through Oracle's Security Alert out-of-band program are only available for versions under Premier or Extended Support; older unsupported versions remain vulnerable and will not receive fixes
  • ·Oracle Web Services Manager is installed as part of Oracle Fusion Middleware Infrastructure — patching scope must include the full Fusion Middleware stack, not just standalone Identity Manager deployments
  • ·Affected versions are specifically 12.2.1.4.0 and 14.1.2.1.0 for both Oracle Identity Manager and Oracle Web Services Manager; other versions are not listed as affected
