What happened

A critical vulnerability in the Data Guard Management component of Oracle Enterprise Manager for Oracle Database allows a low-privileged attacker with HTTP network access to fully compromise the product, with a scope change affecting other products.

Why it is dangerous: A successful attack gives full control over confidentiality, integrity and availability, and can spread to other systems connected to the management tool. Organizations running Enterprise Manager for databases are at risk.
