Hard-coded recovery key in IBM Guardium lets local attackers recover the root password

IBM Guardium Data Protection 12.2 ships a hard-coded recovery key in its passkey component, letting a local attacker recover the root password.

ELI5

Explain it like I’m five

The safe comes with a master key, and the master key is printed in the instruction manual that ships in the box.

SIMPLIFIED_ATTACK_PATH03 STEPS
  1. 01Local access

    A local attacker obtains the hard-coded recovery key from the pkcrypto passkey component.

  2. 02Weak protection

    The weak cryptographic protection around the root secret is undone with the key.

  3. 03Root password

    The attacker recovers the root password and gains root privileges.

What happened

IBM Guardium Data Protection 12.2 is vulnerable due to weak cryptographic protection and a hard-coded recovery key in the pkcrypto passkey component, according to the IBM security bulletin. A local attacker can recover the root password and gain root privileges. IBM rates it high at CVSS 8.4.

What to do

  1. Confirm which Guardium Data Protection 12.2 appliances are in use.
  2. Apply the remediation from the IBM security bulletin as soon as it is available in your environment.
  3. Limit local and console access to the appliances until patched.
  4. Rotate the root password and any credentials stored on affected appliances after patching.

Management note

Hard-coded keys mean the secret was never secret. Patching closes the hole, but credentials that lived on affected boxes should be rotated as a matter of routine.
