Executive Summary

CVE-2020-37016 is an unquoted service path vulnerability in BarcodeOCR version 19.3.6. This means that the service executable path is not enclosed in quotes, allowing local attackers to place malicious executables in directories along the service path. When the system starts, these malicious executables can be run with elevated LocalSystem privileges, enabling attackers to execute arbitrary code with high-level control over the system. [2, 3]

Impact Analysis

This vulnerability can allow a local attacker to escalate their privileges by executing arbitrary code with LocalSystem privileges during system startup. This means the attacker can gain full control over the affected system, potentially leading to unauthorized access, data manipulation, or disruption of system operations. [2, 3]

Detection Guidance

This vulnerability can be detected by checking for unquoted service paths in the BarcodeOCR service configuration. Commands such as WMIC (Windows Management Instrumentation Command-line) and service query commands can be used to identify unquoted service paths. For example, using WMIC to query the service executable path and inspecting if the path is not enclosed in quotes can reveal the vulnerability. [2]

Mitigation Strategies

Immediate mitigation steps include correcting the unquoted service path by enclosing the executable path in quotes to prevent execution of malicious executables. Additionally, restricting local user permissions to prevent unauthorized file placement in directories along the service path and applying any available patches or updates from the vendor are recommended.
