Oracle Issues Urgent Alert for Critical RCE Flaw in Identity and Web Services Manager
Oracle has released an urgent security alert for a critical Remote Code Execution (RCE) vulnerability, tracked as CVE-2026-21992, affecting Oracle Identity Manager and Oracle Web Services Manager. The flaw allows unauthenticated attackers to remotely compromise systems by sending specially crafted network packets, enabling arbitrary code execution on vulnerable servers.
Exploitation of this vulnerability could grant threat actors deep system access, allowing them to deploy malware, steal sensitive corporate identity data, or move laterally within an enterprise network. The flaw is rated under CVSS 3.1, though Oracle has withheld technical exploit details to prevent immediate weaponization.
The vulnerability impacts Oracle Fusion Middleware versions 12.2.1.4.0 and 14.1.2.1.0 for both affected products. Oracle has released patches under KB878741, but only for versions covered by Premier Support or Extended Support. Organizations running end-of-life software must upgrade to supported releases before applying fixes.
Given the severity of the flaw and the risk of exploitation by advanced persistent threats, Oracle emphasizes the need for immediate patch deployment to secure identity management infrastructure. The vulnerability operates over standard network protocols, leaving even HTTPS-secured systems exposed until updates are applied.
