Executive Summary

This vulnerability is an unquoted service path issue in the Windows service configuration of the Flame II HSPA USB Modem. The service executable path 'C:\Program Files (x86)\Internet Telcel\ApplicationController.exe' is not enclosed in quotes. Because the path contains spaces, Windows may misinterpret it and execute a malicious executable placed by an attacker in a higher-level directory. This allows an attacker with local access to execute arbitrary code with elevated system privileges. [2, 3]

Impact Analysis

An attacker with local access can exploit this vulnerability to execute arbitrary code with elevated system privileges on the affected system. This can lead to a full compromise of the system's confidentiality, integrity, and availability, allowing the attacker to perform unauthorized actions with high privileges. [2, 3]

Detection Guidance

You can detect this vulnerability on your Windows system by checking the service configuration for unquoted service paths, especially for the 'FLAME II HSPA USB MODEM Service'. Useful commands include: - Using WMIC to list services with automatic start mode excluding Windows system paths and quoted paths: wmic service get name, displayname, pathname, startmode | findstr /i "Auto" | findstr /i /v "C:\Windows\\" | findstr /i /v '"' - Using SC to query the specific service configuration: sc qc "FLAME II HSPA USB MODEM Service" These commands help identify if the service executable path is unquoted and contains spaces, which indicates the vulnerability. [2]

Mitigation Strategies

Immediate mitigation steps include correcting the unquoted service path by enclosing the executable path in quotation marks to prevent Windows from misinterpreting the path. Specifically, update the service configuration so that the binary path is quoted, e.g., "C:\Program Files (x86)\Internet Telcel\ApplicationController.exe". Additionally, restrict local access to the system to prevent attackers from exploiting the vulnerability, as it requires local access. If possible, check for vendor patches or updates addressing this issue. [2, 3]
