CVE-2025-12507 is a vulnerability classified under CWE-428 (Unquoted Search Path or Element) affecting the Bizerba Communication Server (BCS) service within the _connect.BRAIN product. The root cause is an unquoted service path in Windows, which leads to a security risk because Windows searches for executables along the service path in a specific order. If the path contains spaces and is not enclosed in quotes, Windows may mistakenly execute a malicious executable placed by an attacker in a directory earlier in the search order. This vulnerability requires low privileges (PR:L) but no user interaction (UI:N) and can be exploited locally (AV:L). The scope is changed (S:C), meaning the exploit can affect resources beyond the initially compromised component. The impact is severe, with high confidentiality, integrity, and availability impacts (C:H/I:H/A:H). An attacker with limited privileges could escalate their control by executing arbitrary code with the service's privileges, potentially leading to full system compromise. Although no public exploits are currently known, the vulnerability is critical due to the ease of exploitation and the potential damage. The affected version is listed as 0.0, which likely indicates the initial or a specific early release of the product. No patches have been linked yet, so mitigation relies on configuration changes and monitoring.

For European organizations, the impact of CVE-2025-12507 can be significant, especially in industries where Bizerba's weighing, labeling, and communication solutions are integrated into operational technology (OT) environments. Successful exploitation could allow attackers to execute arbitrary code with elevated privileges, potentially disrupting production lines, corrupting data, or causing denial of service. This could lead to financial losses, regulatory non-compliance (e.g., GDPR if personal data is affected), and reputational damage. The vulnerability's ability to compromise confidentiality, integrity, and availability simultaneously makes it a critical risk for supply chain security and operational continuity. Organizations in retail, manufacturing, logistics, and food processing sectors, where Bizerba products are commonly deployed, are particularly vulnerable. The local attack vector suggests that attackers would need some level of access, possibly through compromised internal systems or insider threats, making internal security controls and network segmentation crucial.

1. Immediately verify and correct the service path for the Bizerba Communication Server (BCS) service by ensuring the executable path is fully quoted to prevent Windows from misinterpreting it. 2. Restrict write permissions on all directories in the service path to prevent unprivileged users from placing malicious executables. 3. Implement strict access controls and monitoring on systems running _connect.BRAIN, focusing on file system changes and service configurations. 4. Use application whitelisting to prevent unauthorized executables from running, especially in directories involved in service execution. 5. Employ endpoint detection and response (EDR) solutions to detect suspicious process creation and privilege escalation attempts. 6. Conduct regular audits of service configurations and permissions on Windows hosts in the environment. 7. Engage with Bizerba for official patches or updates and apply them promptly once available. 8. Educate internal teams about the risks of unquoted service paths and the importance of least privilege principles to reduce attack surface.
