CVE-2026-32680 Overview
CVE-2026-32680 is an insecure permissions vulnerability in the RATOC RAID Monitoring Manager for Windows installer. When users customize the installation folder to a non-default location, the installer fails to properly configure Access Control Lists (ACLs) on the destination directory. This misconfiguration allows non-administrative users to modify the contents of the installation folder, potentially enabling arbitrary code execution with SYSTEM privileges.
Critical Impact
Non-administrative users can exploit insecure folder permissions to replace legitimate binaries or configuration files, leading to privilege escalation and arbitrary code execution with SYSTEM privileges.
Affected Products
- RATOC RAID Monitoring Manager for Windows (custom installation path configurations)

Technical Details for CVE-2026-32680
Vulnerability Analysis
This vulnerability stems from improper handling of file system permissions during the software installation process. When users opt to install RATOC RAID Monitoring Manager to a custom directory rather than the default installation path, the installer creates the target folder with overly permissive ACLs.
The RATOC RAID Monitoring Manager runs with elevated privileges to perform system-level RAID monitoring tasks. When the installation directory lacks proper access restrictions, any local user on the system can write to or modify files within that directory. This creates a classic privilege escalation scenario where an attacker with limited user access can hijack the execution flow of a privileged service.
The vulnerability is classified under CWE-276 (Incorrect Default Permissions), which describes situations where software sets insecure permissions for objects, giving attackers the ability to read or modify sensitive data or perform unauthorized actions.
Root Cause
The root cause is the installer's failure to properly set restrictive ACLs when creating custom installation directories. While default installation paths typically inherit secure permissions from their parent directories (such as C:\Program Files), custom paths may not have these protections. The installer should explicitly configure appropriate ACLs regardless of the installation location but fails to do so.
Attack Vector
The attack requires local access to the system where RATOC RAID Monitoring Manager is installed with a custom installation path. An attacker with low-privilege access can exploit this vulnerability through the following approach:
- Identify systems where RATOC RAID Monitoring Manager is installed to a custom directory
- Verify that the installation folder has weak ACLs allowing write access
- Replace legitimate executable files, DLLs, or configuration files with malicious versions
- Wait for the RAID Monitoring Manager service to restart or trigger a reload
- Achieve code execution with SYSTEM privileges when the service loads the modified components
This is a local attack that does not require user interaction, making it particularly dangerous in multi-user environments or scenarios where attackers have already gained initial foothold on a system.
Detection Methods for CVE-2026-32680
Indicators of Compromise
- Unexpected modifications to files within RATOC RAID Monitoring Manager installation directories
- Unusual file timestamps or hash mismatches on binaries in the installation folder
- New or modified DLL files in the installation directory that don't match vendor signatures
- Suspicious process execution chains originating from the RAID Monitoring Manager service
Detection Strategies
- Monitor file integrity on RATOC RAID Monitoring Manager installation directories using file integrity monitoring (FIM) solutions
- Audit ACL configurations on installation directories during security assessments
- Deploy endpoint detection and response (EDR) solutions to identify privilege escalation attempts through DLL hijacking or binary replacement
- Create detection rules for unexpected child processes spawned by the RAID Monitoring Manager service
Monitoring Recommendations
- Enable Windows Security Event logging for file system access events (Event IDs 4663, 4656) on critical installation directories
- Configure alerts for any non-installer processes writing to the RAID Monitoring Manager installation folder
- Implement baseline monitoring for service executable hashes and alert on changes
- Review Process Creation events (Event ID 4688) for suspicious activity from the monitoring service
How to Mitigate CVE-2026-32680
Immediate Actions Required
- Verify ACL configurations on existing RATOC RAID Monitoring Manager installations and manually restrict permissions if installed to custom paths
- Remove write permissions for non-administrative users on the installation directory and all subdirectories
- Consider reinstalling to the default installation path if feasible
- Apply the latest security update from RATOC Systems
Patch Information
RATOC Systems has released a security update to address this vulnerability. Administrators should obtain the updated installer from the Ratoc Systems RAID Manager Update page. Additional details about this vulnerability are available in the JVN Advisory JVN08057419.
Workarounds
- Manually configure restrictive ACLs on custom installation directories using icacls or Windows Security settings
- Use the default installation path (C:\Program Files\) which inherits more secure permissions from the parent directory
- Implement application whitelisting to prevent unauthorized executables from running within the installation directory
- Deploy file integrity monitoring to detect unauthorized modifications to installation files
# Configuration example
# Manually set restrictive ACLs on the custom installation directory
# Replace <CustomInstallPath> with the actual installation path
icacls "<CustomInstallPath>" /inheritance:r
icacls "<CustomInstallPath>" /grant:r "SYSTEM:(OI)(CI)F"
icacls "<CustomInstallPath>" /grant:r "Administrators:(OI)(CI)F"
icacls "<CustomInstallPath>" /grant:r "Users:(OI)(CI)RX"
