CVE-2026-16708
8.3IBM · Db2 Mirror for i
A vulnerability in IBM Db2 Mirror for i allows an unauthenticated, remote attacker to gain control of system or configuration settings through external manipulation.
Executive summary
An unauthenticated remote code execution vulnerability in IBM Db2 Mirror for i poses a critical risk to system integrity and availability.
Vulnerability
This issue is caused by improper external control of system or configuration settings (CWE-15). It allows an unauthenticated attacker to manipulate system configurations, potentially leading to full system compromise.
Business impact
The CVSS score of 8.3 reflects a high severity rating, indicating that successful exploitation could lead to total loss of system confidentiality, integrity, and availability. Compromise of the Db2 Mirror environment can disrupt critical database synchronization services and provide attackers with a foothold to pivot into sensitive corporate data environments.
Remediation
Immediate Action: Apply the appropriate Program Temporary Fix (PTF) for your specific release: SJ10947 for version 7.4, SJ10961 for version 7.5, or SJ10948 for version 7.6 via IBM Fix Central.
Proactive Monitoring: Monitor system logs for unauthorized configuration changes or attempts to modify system parameters by unknown users.
Compensating Controls: Ensure the IBM i environment is isolated from the public internet and restrict access to the Db2 Mirror management ports to trusted administrative subnets.
Exploitation status
Public Exploit Available: No (exploit_available: false)
Analyst recommendation
Given the potential for unauthorized system configuration, organizations must prioritize the application of the vendor-provided PTFs. Failure to patch these versions leaves the database infrastructure exposed to severe manipulation risks; therefore, immediate maintenance windows should be scheduled to implement these fixes.
