Mitigation Strategies

Immediate mitigation steps include updating DiskBoss to a fixed version if available, or manually correcting the service executable paths by enclosing them in quotes to prevent exploitation. Additionally, restrict low-privileged user access to directories in the service path to prevent placing malicious executables. Rebooting the system after applying fixes or updates will ensure the changes take effect. [2, 4]

Executive Summary

This vulnerability in Flexsense DiskBoss 11.7.28 allows unauthenticated attackers to elevate their privileges by exploiting an unquoted service path. Attackers can specify a malicious service name using the 'sc qc' command, which leads to remote code execution during system startup or reboot with escalated privileges.

Impact Analysis

The vulnerability can allow attackers to execute arbitrary system commands with elevated privileges remotely, potentially compromising the affected system's security and control.

Detection Guidance

This vulnerability can be detected by checking the service configuration for unquoted service paths using the Windows command `sc qc <service_name>`. Specifically, you should inspect the DiskBoss related services to see if their executable paths are unquoted and contain spaces, which can be exploited. For example, run commands like `sc qc DiskBossServiceName` replacing DiskBossServiceName with the actual service name to view the binary path and verify if it is unquoted. [2, 4]
