Impact

IBM Concert Software versions 1.0.0 through 3.0.0 have a use‑after‑free flaw (CWE-416) that allows an attacker who can influence program execution or supply input to corrupt memory, crash the application, or execute arbitrary code, potentially compromising integrity and leading to remote code execution.

Affected Systems

IBM Concert Software from version 1.0.0 up to 3.0.0 is affected. IBM recommends upgrading to Concert Software 3.0.1.1 as the remediation, which resolves the use‑after‑free issue.

Risk and Exploitability

The flaw receives a CVSS score of 9.8, indicating critical severity. EPSS data is not available, and the vulnerability is not listed in the CISA KEV catalog. Because the exploitation requires an attacker to influence execution or input, the attack vector is likely remote if such input can be supplied; local vectors are also possible. Given the high severity and the potential for arbitrary code execution, the risk remains high until a patched version is deployed.

Remediation

Vendor Solution

IBM strongly recommends addressing the vulnerability now by upgrading to IBM Concert Software 3.0.1.1 Download IBM Concert Software 3.0.0 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

  • Upgrade to IBM Concert Software 3.0.1.1 via the IBM Entitled Registry and follow the installation instructions to replace any vulnerable instance.
  • Replace all affected environments with the fixed version, ensuring that no instance continues to run a vulnerable episode.
  • If an upgrade cannot be performed immediately, enforce strict input validation and sanitization to reduce the chance that crafted input triggers memory corruption.
