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 located in the file /webui/modules/log/operate.mds. The vulnerability arises from improper handling of the argument start_code, which allows an attacker to perform OS command injection. This means that an attacker can craft malicious input to execute arbitrary operating system commands on the affected system remotely, without requiring authentication or user interaction. The vulnerability is classified as critical in nature due to the potential for remote code execution; however, the CVSS 4.0 score assigned is 6.9, indicating a medium severity level. The CVSS vector highlights that the attack can be performed remotely (AV:N), requires no privileges (PR:N), no user interaction (UI:N), and impacts confidentiality, integrity, and availability to a low or limited extent (VC:L, VI:L, VA:L). The vendor, BDCOM, was contacted early but did not respond or provide a patch, and no official patch links are available at this time. Although no known exploits in the wild have been reported yet, the exploit code has been publicly disclosed, increasing the risk of exploitation. This vulnerability poses a significant threat to organizations using this product for behavior management and auditing, as successful exploitation could lead to unauthorized system control, data compromise, or disruption of auditing functions critical for security monitoring and compliance.

For European organizations, the impact of CVE-2025-1546 can be substantial, especially for those relying on BDCOM's Behavior Management and Auditing System to monitor user activities, enforce policies, and maintain compliance with regulations such as GDPR. Exploitation could allow attackers to execute arbitrary commands remotely, potentially leading to data breaches, manipulation or deletion of audit logs, and disruption of security monitoring capabilities. This undermines the integrity and availability of critical security data and may result in regulatory penalties, loss of customer trust, and operational downtime. Furthermore, since the vulnerability requires no authentication or user interaction, it can be exploited by remote attackers with minimal effort, increasing the risk of widespread attacks. The lack of vendor response and absence of patches exacerbate the threat, leaving organizations exposed. The potential for attackers to gain persistent access or pivot within networks could also facilitate further attacks on sensitive systems, amplifying the overall risk to European enterprises, particularly those in regulated sectors such as finance, healthcare, and government.

Given the absence of an official patch, European organizations should implement immediate compensating controls to mitigate the risk. These include: 1) Restricting network access to the BDCOM Behavior Management and Auditing System interfaces by implementing strict firewall rules and network segmentation to limit exposure to trusted IP addresses only. 2) Deploying Web Application Firewalls (WAFs) with custom rules to detect and block suspicious input patterns targeting the start_code parameter to prevent command injection attempts. 3) Monitoring system and application logs closely for unusual activities or command execution traces related to the vulnerable function. 4) Conducting regular vulnerability scans and penetration tests focusing on this component to identify exploitation attempts. 5) If feasible, temporarily disabling or restricting the use of the log_operate_clear function until a vendor patch is released. 6) Engaging with BDCOM or third-party security providers to seek updates or unofficial patches. 7) Preparing incident response plans tailored to potential exploitation scenarios involving this vulnerability. These measures should be combined with ongoing user awareness and security hygiene to reduce the attack surface.
