CVE-2025-9000 Overview
CVE-2025-9000 affects Mechrevo Control Center GX V2 version 5.56.51.48. The vulnerability resides in the reg file handler component and stems from an uncontrolled search path element [CWE-426]. A local attacker with low privileges can manipulate the search path to influence how the application resolves and loads resources. Successful exploitation impacts confidentiality, integrity, and availability on the affected host. The exploit has been publicly disclosed, though the attack complexity is high and reliable exploitation is considered difficult.
Critical Impact
Local attackers can leverage uncontrolled search path resolution in the reg file handler to execute code in the context of the vulnerable application, compromising confidentiality, integrity, and availability.

Technical Details for CVE-2025-9000
Vulnerability Analysis
CVE-2025-9000 is an uncontrolled search path element vulnerability [CWE-426] in Mechrevo Control Center GX V2. The flaw lives in the component responsible for processing reg files. When the application resolves dependencies or auxiliary resources during reg file handling, it consults a search path that an attacker with local access can influence. This allows a malicious resource to be resolved instead of the intended one. The result is arbitrary code or configuration loading within the trust boundary of the application.
Root Cause
The root cause is improper control of the search path used by the reg file handler. The application does not enforce a fully qualified or trusted lookup order when locating dependent binaries or supporting files. An attacker who can place a crafted file in a directory that appears earlier in the search order can supplant the legitimate resource. This class of flaw commonly manifests as DLL search order hijacking or PATH abuse on Windows systems.
Attack Vector
Exploitation requires local access and low privileges on the target host. The attacker plants a malicious file in a location that the vulnerable process searches before the legitimate directory. When a user or system component invokes the reg file handler, the crafted file is loaded. Attack complexity is high, indicating that specific conditions such as directory write permissions, timing, or user interaction with a reg file may be required. Public disclosure of the technique increases exposure.
No verified proof-of-concept code is available in trusted repositories. See the VulDB entry #320029 for additional technical context.
Detection Methods for CVE-2025-9000
Indicators of Compromise
- Unexpected files (DLLs, executables, or configuration files) placed in directories adjacent to the Mechrevo Control Center GX V2 install path.
- Process creation events where control_center_gx_v2 loads modules from user-writable directories.
- Anomalous reg file interactions preceding suspicious child process execution.
Detection Strategies
- Monitor image loads by Mechrevo Control Center processes and flag any modules resolved from non-standard paths.
- Alert on write operations to directories that appear in the Control Center's effective search path from non-privileged users.
- Correlate reg file handler invocations with subsequent spawn of shells, script interpreters, or LOLBins.
Monitoring Recommendations
- Collect Sysmon Event IDs 1, 7, and 11 to capture process creation, module loads, and file creation for the affected binary.
- Baseline the legitimate modules loaded by the Control Center and alert on deviations.
- Retain endpoint telemetry for post-incident review across all hosts running the affected Mechrevo build.
How to Mitigate CVE-2025-9000
Immediate Actions Required
- Inventory endpoints running Mechrevo Control Center GX V2 5.56.51.48 and restrict local user write access to the application directory and its search paths.
- Enforce least-privilege on interactive accounts to limit the ability to place files in exploitable locations.
- Block execution of untrusted reg files via application control policies until a vendor patch is available.
Patch Information
No vendor advisory or patched version is listed in the referenced NVD or VulDB records at the time of publication. Track the VulDB CTI entry #320029 and Mechrevo vendor channels for a fix. Once a corrected build is released, deploy it across all affected endpoints and validate that the reg file handler resolves resources from trusted, absolute paths only.
Workarounds
- Remove or disable Mechrevo Control Center GX V2 on systems that do not require it.
- Apply NTFS ACLs to prevent standard users from writing to the application directory and any directories in its module search path.
- Use AppLocker or Windows Defender Application Control to restrict which modules the Control Center process is permitted to load.
- Educate users to avoid opening untrusted reg files from removable media or downloads.
