CVE-2023-53912 is a vulnerability identified in BiniSoft's USB Flash Drives Control software, version 4.1.0.0, specifically involving an unquoted service path in the Windows service configuration. The affected service executable is located at 'C:\Program Files\USB Flash Drives Control\usbcs.exe'. Because the path contains spaces and is not enclosed in quotes, Windows may incorrectly interpret the path when launching the service, searching for executables in unintended directories. A local attacker with low privileges can exploit this by placing a malicious executable in one of the directories parsed before the legitimate executable, causing the system to run the attacker's code with the service's privileges. This leads to arbitrary code execution and potential privilege escalation on the affected Windows host. The vulnerability requires local access but no user interaction or elevated privileges to initiate exploitation. The CVSS 4.0 base score is 8.5, indicating a high severity due to the combination of low attack complexity, no required user interaction, and high impact on confidentiality, integrity, and availability. Although no public exploits are currently known, the vulnerability is significant because unquoted service path issues are well-understood and relatively easy to exploit by attackers with local access. The vulnerability affects only version 4.1.0.0 of the product, and no patches or updates are currently linked, emphasizing the need for immediate mitigation steps by administrators. This vulnerability is particularly relevant for environments where USB Flash Drives Control is deployed, especially in organizations that rely on USB device management for security or operational purposes.

For European organizations, this vulnerability poses a significant risk of local privilege escalation on Windows systems running the affected BiniSoft USB Flash Drives Control software. Successful exploitation could allow attackers to gain elevated privileges, potentially leading to unauthorized access to sensitive data, disruption of system operations, or further lateral movement within corporate networks. This is especially critical in sectors with stringent data protection requirements such as finance, healthcare, and government institutions. The ability to escalate privileges locally can undermine endpoint security controls and facilitate more severe attacks, including ransomware deployment or data exfiltration. Since the vulnerability requires local access, the threat is heightened in environments with many users or where endpoint security is lax. Additionally, organizations using USB device control software are often focused on preventing data leakage or malware introduction via removable media, so a vulnerability in this software could undermine these security measures. The lack of known exploits in the wild currently reduces immediate risk but does not eliminate the potential for future exploitation, making proactive mitigation essential.

1. Immediately audit all Windows services on systems running USB Flash Drives Control to identify unquoted service paths and correct them by enclosing paths in double quotes. 2. Restrict local user permissions to prevent unauthorized users from writing to directories in the service path, especially 'C:\Program Files\USB Flash Drives Control\'. 3. Implement application whitelisting to prevent execution of unauthorized binaries in service-related directories. 4. Monitor and log service start events and unexpected executable launches to detect potential exploitation attempts. 5. Limit local administrative privileges and enforce the principle of least privilege to reduce the risk of local attackers exploiting this vulnerability. 6. Engage with BiniSoft for official patches or updates addressing this vulnerability and apply them promptly once available. 7. Use endpoint detection and response (EDR) tools to detect anomalous behavior indicative of privilege escalation attempts. 8. Educate IT staff and users about the risks of local privilege escalation and the importance of maintaining secure service configurations. 9. Consider temporary disabling or replacing the affected service if feasible until a patch is released. 10. Regularly review and harden service configurations across all Windows endpoints to prevent similar vulnerabilities.
