  5. ResultAttacker controls the backup server

What happened

Oracle Secure Backup versions 19.1.0.0.0 and 19.1.0.1.0 contain a flaw in the Backup and Restore component that allows unauthenticated remote attackers over TCP to fully compromise the product (CVSS 9.8).

Why it is dangerous: A successful attack gives full control of the backup server, exposing confidentiality, integrity, and availability of backed-up data. Organizations running these versions with network access to the backup server are at risk.

Are you affected?

You are affected if you run Oracle Secure Backup 19.1.0.0.0 or 19.1.0.1.0 and its TCP service is reachable from networks an attacker could use.

Oracle Secure Backup 19.1.0.0.0; Oracle Secure Backup 19.1.0.1.0

What to do

  1. Check whether your Oracle Secure Backup version is 19.1.0.0.0 or 19.1.0.1.0.
  2. Restrict network access to the Oracle Secure Backup TCP service so only required hosts can reach it.
  3. Apply the fix from Oracle's Critical Patch Update or security advisory as soon as it is available for your version.
  4. Monitor the backup server for unexpected logins or changes.
