CVE-2025-2605 is a critical OS command injection vulnerability (CWE-78) identified in Honeywell's MB-Secure and MB-Secure PRO products. This vulnerability arises from improper neutralization of special elements in OS commands, allowing an attacker with limited privileges (PR:L) to execute arbitrary operating system commands without requiring user interaction (UI:N). The vulnerability affects MB-Secure versions from V11.04 up to but not including V12.53, and MB-Secure PRO versions from V01.06 up to but not including V03.09. Exploitation of this flaw can lead to complete compromise of confidentiality, integrity, and availability (C:I:A all high), as the attacker can abuse privileges to execute commands that could manipulate system files, extract sensitive data, disrupt services, or pivot within the network. The CVSS 3.1 base score of 9.9 reflects the critical nature of this vulnerability, with network attack vector (AV:N), low attack complexity (AC:L), and scope change (S:C), indicating that the vulnerability can affect resources beyond the initially compromised component. Although no known exploits are currently reported in the wild, the severity and ease of exploitation make this a high-risk issue requiring immediate attention. Honeywell recommends updating to the latest versions beyond the affected ranges to remediate this vulnerability. The lack of available patches at the time of reporting suggests organizations should prioritize mitigation strategies and monitor for vendor updates.

For European organizations, the impact of CVE-2025-2605 is significant, especially for those relying on Honeywell MB-Secure products for critical infrastructure security and industrial control systems. Successful exploitation could lead to unauthorized command execution, resulting in data breaches, operational disruptions, and potential sabotage of industrial processes. Given Honeywell's prominence in sectors such as energy, manufacturing, and building management across Europe, exploitation could affect critical infrastructure, causing cascading effects on public safety and economic stability. The vulnerability's ability to escalate privileges and affect system integrity and availability poses risks to compliance with stringent European data protection regulations (e.g., GDPR) and critical infrastructure protection directives (e.g., NIS Directive). Additionally, the cross-scope impact means that attackers could leverage this vulnerability to move laterally within networks, increasing the attack surface and complicating incident response efforts.

European organizations should immediately assess their deployment of Honeywell MB-Secure and MB-Secure PRO products to identify affected versions. Until official patches beyond V12.53 (MB-Secure) and V03.09 (MB-Secure PRO) are applied, organizations should implement strict network segmentation to isolate vulnerable systems from broader enterprise networks, limiting potential lateral movement. Employ application whitelisting and strict command execution policies to detect and block unauthorized OS command invocations. Monitor system and application logs for unusual command execution patterns indicative of exploitation attempts. Enforce least privilege principles rigorously to minimize the privileges of users and service accounts interacting with MB-Secure products. Additionally, deploy intrusion detection/prevention systems (IDS/IPS) with signatures or heuristics targeting OS command injection attempts. Engage with Honeywell support channels to obtain timely updates and patches, and validate the integrity of updates before deployment. Finally, conduct targeted penetration testing and vulnerability scanning focused on this CVE to proactively identify exploitation attempts.
