A critical vulnerability, tracked as CVE-2026-21992, has been identified in Oracle Identity Manager (OIM) and Oracle Web Services Manager (OWSM). This flaw enables unauthenticated remote code execution (RCE), posing a severe risk to organizations that rely on these platforms for identity and access management. With a CVSS score of 9.8, the issue is classified as critical, and organizations should prioritize immediate patching or mitigation to reduce exposure.

Vulnerability Details:

  • CVE-ID: CVE-2026-21992
  • CVSS Score: 9.8 (Critical) 
  • EPSS Score: 0.03%
  • Vulnerability: Remote Code Execution vulnerability 
  • Affected Product: Oracle Identity Manager and Oracle Web Services Manager

The root cause of CVE-2026-21992 stems from the absence of proper authentication checks in a critical function within both Oracle Identity Manager and Oracle Web Services Manager. In Oracle Identity Manager, the issue resides in the REST WebServices component, while in Oracle Web Services Manager, it affects the Web Services Security module. Due to this missing authentication control, remote attackers can exploit the flaw to execute arbitrary code on vulnerable systems without requiring any valid credentials.

Impact

Successful exploitation of this vulnerability can have severe consequences. An attacker may gain full control over the affected system, enabling a range of malicious activities, including:

  • Deployment of malware
  • Exfiltration of sensitive or confidential data
  • Lateral movement within the network to compromise additional systems

Affected Products

The vulnerability impacts the following versions of Oracle Identity Manager and Web Services Manager:

  • Oracle Identity Manager versions 12.2.1.4.0 and 14.1.2.1.0
  • Oracle Web Services Manager versions 12.2.1.4.0 and 14.1.2.1.0

Tactics and Techniques include:

  • TA0001 – Initial Access: Exploiting a public-facing application to gain initial entry into the network.
  • TA0002 – Execution: Executing malicious code on the compromised system.
  • T1190 – Exploit Public-Facing Application: Leveraging vulnerabilities in public-facing applications to execute arbitrary commands.

Mitigation & Recommendations

  • Apply the security updates provided by Oracle in their Security Alert for CVE-2026-21992 without delay.
  • Ensure that your Oracle Identity Manager and Web Services Manager installations are on actively supported versions.
  • Regularly apply all Security Alerts and Critical Patch Updates from Oracle to stay protected against known vulnerabilities.
