A high-severity vulnerability in Oracle User Management allows authenticated attackers to achieve full system takeover, posing a significant risk to organizational data integrity.

The vulnerability exists within the Internal Operations component of Oracle User Management and is accessible via HTTP. It requires an attacker to possess low-level privileges to successfully execute a compromise.
