CVE-2026-5065

8.8

IBM · Controller

IBM Controller contains a vulnerability involving the use of hard-coded credentials, which could allow an authenticated attacker to gain unauthorized access to sensitive system functions.

Executive summary

A hard-coded credential vulnerability in IBM Controller allows authenticated attackers to potentially compromise system integrity and security.

Vulnerability

The vulnerability involves the use of hard-coded credentials (CWE-798). The attack vector requires the attacker to have at least low-level privileges (PR:L), indicating that the attacker must already be authenticated to the application to exploit this flaw.

Business impact

A CVSS score of 8.8 reflects the high potential for unauthorized access, data manipulation, or denial of service once an attacker has authenticated. This vulnerability could allow an internal user or a compromised account to escalate privileges or access administrative functions, potentially leading to unauthorized financial or operational data exposure.

Remediation

Immediate Action: Apply the recommended security updates provided by IBM through the IBM Support portal to remove the hard-coded credentials.

Proactive Monitoring: Review application access logs for unusual administrative activity or attempts to access configuration files that should remain restricted.

Compensating Controls: Implement strict network segmentation and restrict access to the IBM Controller interface to only authorized personnel/subnets to minimize the pool of potential attackers.

Exploitation status

Public Exploit Available: Unknown

Analyst recommendation

Organizations utilizing IBM Controller must prioritize the application of the vendor-supplied security patches. Given the nature of hard-coded credentials, this represents a fundamental security weakness that must be remediated to ensure the integrity of the financial and management data stored within the platform.
