Executive Summary

IBM Db2 versions 11.5.0 through 11.5.9 and 12.1.0 through 12.1.5 are vulnerable to privilege escalation when the db2locssh feature is enabled with the Db2 instance. This allows an attacker with local access to gain elevated privileges.

Detection Guidance

Check if db2locssh is enabled in your Db2 instance configuration. Run: db2 get instance <instance_name> | grep -i ssh. If enabled, the vulnerability may exist.

Impact Analysis

An attacker with local access could exploit this to gain higher privileges on the system, potentially leading to unauthorized data access, system modifications, or further attacks within the environment.

Compliance Impact

This vulnerability could lead to unauthorized access or modification of sensitive data, which may violate compliance requirements such as GDPR (data protection) or HIPAA (healthcare data privacy). Organizations must apply patches to maintain compliance.

Mitigation Strategies

Apply the security updates provided by IBM for your Db2 version via Fix Central. Update to V11.5.9, V12.1.4, or V12.1.5 to mitigate the risk.
