CVE-2025-55116 is a stack-based buffer overflow vulnerability identified in BMC's Control-M/Agent software, specifically affecting versions 9.0.18 through 9.0.20 and potentially earlier unsupported releases. Control-M/Agent is a widely used workload automation and job scheduling agent deployed in enterprise environments to manage batch jobs and workflows. The vulnerability arises from improper bounds checking on stack buffers, allowing an attacker with local access to the system to overwrite memory on the stack. This can lead to arbitrary code execution with elevated privileges, effectively enabling local privilege escalation. The attacker must have at least low-level privileges on the host to exploit the flaw, but no user interaction is required. The vulnerability is classified under CWE-121 (Stack-based Buffer Overflow), a common and dangerous software weakness. The CVSS 4.0 base score is 9.3, reflecting critical severity due to the high impact on confidentiality, integrity, and availability, combined with relatively low attack complexity and no need for user interaction. The affected versions are out of official support, complicating mitigation efforts. No patches or vendor-provided fixes are currently available, and no active exploitation has been reported. This vulnerability poses a significant risk to organizations relying on Control-M/Agent for critical automation tasks, as successful exploitation could allow attackers to gain unauthorized administrative control over affected systems.

The impact of CVE-2025-55116 is substantial for organizations worldwide using the affected Control-M/Agent versions. Successful exploitation allows local attackers to escalate privileges, potentially gaining full administrative control over the host system. This can lead to unauthorized access to sensitive data, disruption of automated workflows, and compromise of system integrity and availability. Given Control-M/Agent's role in managing critical batch jobs and enterprise workflows, exploitation could disrupt business operations, cause data loss or corruption, and facilitate further lateral movement within networks. The vulnerability's critical severity and high CVSS score indicate that the risk extends beyond isolated incidents, potentially affecting entire IT environments. Organizations running unsupported versions face additional challenges due to lack of official patches, increasing the window of exposure. The absence of known exploits in the wild currently reduces immediate risk but does not diminish the urgency for remediation, as attackers may develop exploits rapidly once details become widely known.

To mitigate CVE-2025-55116, organizations should prioritize upgrading to the latest supported versions of BMC Control-M/Agent where the vulnerability is addressed. If immediate upgrade is not feasible, implement strict access controls to limit local system access only to trusted administrators and users. Employ host-based intrusion detection systems (HIDS) and endpoint protection solutions to monitor for anomalous behavior indicative of exploitation attempts. Conduct thorough audits of user privileges and remove unnecessary local accounts or restrict their permissions. Network segmentation can reduce the risk of lateral movement if a system is compromised. Additionally, maintain comprehensive logging and regularly review logs for suspicious activity related to Control-M/Agent processes. Engage with BMC support or security advisories for any interim patches or workarounds. Finally, educate system administrators about the risks of running unsupported software versions and the importance of timely patch management.
