CVE-2020-36981
7.8Motorola · Device Manager
Motorola Device Manager versions 2.4.5 and 2.5.4 are vulnerable to an unquoted service path flaw in the PST Service, enabling local privilege escalation.
Executive summary
An unquoted service path vulnerability in Motorola Device Manager 2.4.5 and 2.5.4 allows local attackers to execute arbitrary code with elevated system privileges.
Vulnerability
The application utilizes an unquoted service path for the PST Service (ForwardDaemon.exe), which allows a local attacker to insert malicious executables in the path hierarchy. Because the service runs with LocalSystem privileges, the injected code executes with the same elevated permissions upon service startup.
Business impact
Successful exploitation allows a local user to escalate their privileges to LocalSystem, effectively granting them full control over the compromised machine. This represents a significant security risk, as it facilitates complete system compromise, unauthorized data access, and potential persistence mechanisms. The CVSS score of 7.8 reflects the high severity of this local privilege escalation vector.
Remediation
Immediate Action: As no official patch is currently available, administrators should restrict local access to the affected file system paths to prevent unauthorized binary placement. If the software is not required for business operations, uninstalling Motorola Device Manager is the most effective mitigation.
Proactive Monitoring: Review system logs for unexpected service restarts or modifications to the directory structure within C:\Program Files (x86)\Motorola\MotForwardDaemon. Monitor for the creation of unauthorized executables in the Motorola directory.
Compensating Controls: Implement strict file system permissions on the installation directory to ensure only administrative accounts can write files. Ensure that Endpoint Detection and Response (EDR) solutions are configured to alert on privilege escalation attempts originating from local services.
Exploitation status
Public Exploit Available: Yes, a public proof-of-concept exists via the Exploit Database (EDB-ID 49011 and 49013).
Analyst recommendation
Given the availability of functional exploit code, this vulnerability poses a clear risk to any environment where Motorola Device Manager is installed. Organizations should prioritize the removal of this software or enforce strict host-based access controls to mitigate the potential for privilege escalation until a vendor-supplied update is provided.
