AI-suggested
European organizations should immediately audit their Control-M/Agent configurations to identify if the vulnerable versions (9.0.18 through 9.0.22) are in use and whether the non-default SSL/TLS settings "use_openssl=n" and "JAVA_AR=N" are applied. If these settings are in place, organizations should revert to default SSL/TLS configurations where feasible, particularly enabling OpenSSL usage (i.e., set "use_openssl=y") to mitigate the vulnerability. Network segmentation and strict access controls should be enforced to limit exposure of Control-M/Agent interfaces to trusted internal networks only. Employing intrusion detection and prevention systems (IDS/IPS) with signatures or heuristics targeting anomalous Control-M/Agent traffic can help detect exploitation attempts. Organizations should monitor vendor communications closely for official patches or updates addressing this vulnerability and plan for rapid deployment once available. Additionally, implementing robust logging and alerting on Control-M/Agent error messages and unusual activity can provide early warning signs of exploitation attempts. Finally, conducting penetration testing and vulnerability assessments focused on Control-M/Agent configurations can help validate the effectiveness of mitigations.
Description
A stack-based buffer overflow can be remotely triggered when formatting an error message in the Control-M/Agent when SSL/TLS communication is configured. The issue occurs in the following cases: * Control-M/Agent 9.0.20: SSL/TLS configuration is set to the non-default setting "use_openssl=n"; * Control-M/Agent 9.0.21 and 9.0.22: Agent router configuration uses the non-default settings "JAVA_AR=N" and "use_openssl=n".
