CVE-2021-2458
📋 TL;DR
This vulnerability in Oracle Identity Manager allows low-privileged attackers with network access via HTTP to compromise the system. Successful exploitation requires human interaction from someone other than the attacker and can lead to unauthorized access to critical data or complete access to all Identity Manager accessible data. Affected versions include 11.1.2.2.0, 11.1.2.3.0, 12.2.1.3.0 and 12.2.1.4.0.
💻 Affected Systems
- Oracle Identity Manager
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete compromise of Identity Manager with unauthorized access to all data, potential lateral movement to connected systems, and unauthorized data modification.
Likely Case
Unauthorized access to sensitive identity data, privilege escalation within Identity Manager, and potential data manipulation.
If Mitigated
Limited impact due to network segmentation, strong authentication controls, and monitoring that detects suspicious activity.
🎯 Exploit Status
Requires low privileged access and human interaction from another user. Oracle describes as 'easily exploitable'.
