Description
IBM Concert 1.0 through 3.0.1.1 allows an attacker can supply crafted input that is incorporated into an operating system command without adequate validation or sanitization. Successful exploitation allows remote attackers to execute arbitrary commands on the underlying operating system with the privileges of the affected service.

Impact

IBM Concert software versions 1.0 through 3.0.1.1 contain an unchecked input that is concatenated into an operating system command, allowing a remote attacker to run arbitrary commands on the host with the privileges of the running service, effectively enabling full compromise of the underlying operating system.

Affected Systems

Affected products are IBM Concert Software released as version 1.0 up to 3.0.1.1. The fix is available in IBM Concert Software 3.1.0, which is released under the IBM Entitled Registry.

Risk and Exploitability

The CVSS score of 9.8 classifies this flaw as critical. The EPSS score is not publicly available, but the lack of a listed KEV entry does not lower the risk; the vulnerability can be exploited remotely without authentication by supplying crafted input to the Concert service, giving the attacker the service account's privileges and full control of the host. The high severity and remote attack vector make it a priority for immediate remediation.

Remediation

Vendor Solution

IBM strongly recommends addressing these vulnerabilities now by upgrading to IBM Concert Software 3.1.0 Download IBM Concert Software 3.1.0 from Container software library section of IBM Entitled Registry ( ICR https://myibm.ibm.com/products-services/containerlibrary ) and follow  installation instructions https://www.ibm.com/docs/en/concert  depending on the type of deployment.

OpenCVE Recommended Actions

  • Apply the IBM Concert Software 3.1.0 update or any later patch that removes the command injection flaw.
  • If an immediate upgrade is not possible, restrict network access to the Concert service to trusted hosts or networks to prevent unauthenticated input.
  • Implement hardening measures such as disabling or sanitizing the affected command execution paths, and monitor for suspicious input patterns.
