CVE-2025-1546 is a vulnerability identified in the BDCOM Behavior Management and Auditing System, specifically affecting versions up to 20250210. The flaw exists in the function log_operate_clear within the file /webui/modules/log/operate.mds. The vulnerability arises from improper handling of the argument start_code, which can be manipulated to perform OS command injection. This means an attacker can inject arbitrary operating system commands remotely without any authentication or user interaction, potentially executing commands on the underlying system with the privileges of the affected application. The vulnerability has been publicly disclosed, and although no known exploits are currently reported in the wild, the availability of the exploit code increases the risk of exploitation. The vendor has been contacted but has not responded or provided a patch, leaving systems exposed. The CVSS v4.0 score is 6.9, indicating a medium severity rating, reflecting the ease of remote exploitation without authentication but with limited impact on confidentiality, integrity, and availability. The vulnerability does not require user interaction or privileges, making it accessible to remote attackers. The lack of vendor response and patch availability increases the urgency for organizations to implement mitigations or consider alternative controls to reduce exposure.

For European organizations using BDCOM Behavior Management and Auditing System, this vulnerability poses a significant risk. Successful exploitation could allow attackers to execute arbitrary commands on critical systems, potentially leading to unauthorized data access, system compromise, or disruption of auditing and behavior management functions. This could undermine compliance with European data protection regulations such as GDPR, especially if sensitive personal data is exposed or system integrity is compromised. The remote and unauthenticated nature of the attack vector increases the likelihood of exploitation, particularly in environments where the affected system is exposed to untrusted networks. The absence of vendor patches means organizations must rely on compensating controls to prevent exploitation. Additionally, the auditing system’s role in monitoring behavior and logs means that compromise could facilitate stealthy attacks or cover tracks, further increasing the risk to operational security and incident response capabilities.

Given the lack of an official patch, European organizations should implement the following specific mitigations: 1) Restrict network access to the BDCOM Behavior Management and Auditing System interface by implementing strict firewall rules and network segmentation to limit exposure to trusted management networks only. 2) Employ Web Application Firewalls (WAFs) with custom rules to detect and block suspicious input patterns targeting the start_code parameter, particularly those indicative of command injection attempts. 3) Monitor system and application logs closely for unusual command execution or access patterns that could indicate exploitation attempts. 4) If feasible, disable or restrict the log_operate_clear function or the affected module until a patch is available. 5) Conduct regular vulnerability scanning and penetration testing focused on this component to identify potential exploitation attempts. 6) Consider deploying endpoint detection and response (EDR) solutions on hosts running the affected system to detect anomalous command executions. 7) Engage with BDCOM or third-party security vendors for potential unofficial patches or mitigations. 8) Prepare incident response plans specifically addressing potential exploitation of this vulnerability to ensure rapid containment and remediation.
