Executive Summary

IBM Db2 Genius Hub 1.0 has a vulnerability where a remote authenticated attacker can bypass security restrictions. This happens because the cryptographic algorithm lacks an initialization vector, which is essential for secure encryption.

Impact Analysis

An attacker could exploit this to bypass security measures, potentially gaining unauthorized access to sensitive data or performing actions they should not be able to. However, the attack requires network access, high complexity, and low privileges, making it less likely to occur.

Compliance Impact

This vulnerability could lead to unauthorized data access, which may violate compliance requirements for GDPR or HIPAA. Organizations using this software should address it to maintain regulatory compliance.

Mitigation Strategies

Upgrade IBM Db2 Genius Hub to version 1.1.0 or later to remediate the vulnerability. No workarounds are provided.
