Who should care

Defenders responsible for IBM Concert deployments should assess exposure and verify the use of sufficient cryptographic algorithms. This includes operators, platform administrators, vulnerability management teams, and security teams who need to ensure the security of IBM Concert deployments. They should review the CVE record and source item for details on the vulnerability and take immediate action to prevent the use

Why it matters

Defenders should prioritize verifying the use of sufficient cryptographic algorithms in IBM Concert 1.0 through 3.0.0 and assessing exposure.

  • Decrypt highly sensitive information

Technical summary

IBM Concert 1.0 through 3.0.0 uses weaker than expected cryptographic algorithms that could allow an attacker to decrypt highly sensitive information. This vulnerability is due to the use of insufficiently random values in the software. Defenders should prioritize verifying the use of sufficient cryptographic algorithms in IBM Concert 1.0 through 3.0.0 and assessing exposure. The use of weak cryptographic algorithms can lead to the decryption of highly sensitive information.

Defensive priority

Defenders should prioritize verifying the use of sufficient cryptographic algorithms in IBM Concert 1.0 through 3.0.0 and assessing exposure.

Recommended defensive actions

  • Verify the use of sufficient cryptographic algorithms in IBM Concert 1.0 through 3.0.0
  • Assess exposure of IBM Concert 1.0 through 3.0.0 in the environment
  • Review and update IBM Concert to a version that uses sufficient cryptographic algorithms if available

Evidence notes

The CVE record and source item indicate that IBM Concert uses weaker than expected cryptographic algorithms, potentially allowing decryption of highly sensitive information.
