Exploitation Conditions

RATOC RAID Monitoring Manager for Windows installed to a non-default installation folder with insecure ACLs. Attacker requires local non-administrative user access. No victim interaction needed.

Impact

The CVSS 4.0 vector (AV:L/AC:L/AT:N/PR:L/UI:N) indicates this is a local attack requiring low privileges with low complexity and no user interaction, making it highly exploitable once an attacker has initial access to a system. The vulnerability requires that the software was installed to a custom directory rather than the default location, which may limit the attack surface in practice since many users accept default installation paths. Without available EPSS or KEV data, exploitation likelihood in the wild is uncertain, but the technical simplicity (low complexity, no user interaction required) combined with SYSTEM-level privilege escalation makes this attractive for post-compromise lateral movement and persistence. Organizations using RATOC RAID systems with custom installation paths should prioritize remediation, particularly in multi-user Windows environments where low-privileged accounts exist. The primary risk is in environments where attackers have already gained initial foothold via other means and seek privilege escalation.

Exploit ScenarioDerived

An attacker with low-privileged user access to a Windows system running RATOC RAID Monitoring Manager installed in a custom directory identifies the insecure folder permissions. The attacker replaces a legitimate executable or DLL in the installation directory with a malicious version containing their payload. When the RATOC service or application next starts with SYSTEM privileges, the malicious code executes with full system rights, granting the attacker complete control over the machine for activities such as installing backdoors, stealing credentials, or moving laterally across the network.

AnalysisAIv1 – Mar 26, 2026

RATOC RAID Monitoring Manager for Windows contains an insecure directory permissions vulnerability when the installation folder is customized to a non-default location. The installer fails to properly set access control lists (ACLs) on custom installation directories, allowing non-administrative users to modify folder contents and execute arbitrary code with SYSTEM privileges. With a CVSS 4.0 score of 8.5, this represents a high-severity local privilege escalation vulnerability affecting Windows systems where this RAID management software is installed.

RemediationAI

Apply the security update provided by RATOC Systems as detailed in their advisory at https://www.ratocsystems.com/topics/userinfo/raidmanager202508/. Organizations should verify the file system permissions on their RATOC RAID Monitoring Manager installation directories, particularly if custom paths were selected during installation. Administrators can manually correct ACLs by restricting write access to the installation directory to only SYSTEM and Administrators groups, removing write permissions for standard users and authenticated users groups using Windows icacls or File Explorer security settings. For systems that cannot be immediately patched, limit local user access to affected machines and implement application whitelisting or execution controls to prevent unauthorized binary execution. Monitor the installation directory for unexpected file modifications and consider reinstalling to the default directory path where proper ACLs are automatically applied.

Technical ContextAI · show details

This vulnerability stems from CWE-276 (Incorrect Default Permissions), where the software installer fails to properly configure directory ACLs during custom installations. The affected product is RATOC RAID Monitoring Manager for Windows (CPE: cpe:2.3:a:ratoc_systems,_inc.:ratoc_raid_monitoring_manager_for_windows), a RAID array monitoring and management solution from RATOC Systems. When users choose a non-default installation path during setup, the installer does not apply restrictive file system permissions, leaving the directory writable by low-privileged users. This allows malicious actors to replace legitimate binaries or DLLs with malicious versions that will execute with SYSTEM privileges when the service or application runs, a classic DLL hijacking or binary replacement attack pattern in Windows environments.

DescriptionCVE.org

The installer of RATOC RAID Monitoring Manager for Windows allows to customize the installation folder. If the installation folder is customized to some non-default one, the folder may be left with un-secure ACLs and non-administrative users can alter contents of that folder. It may allow a non-administrative user to execute an arbitrary code with SYSTEM privilege.

Executive ViewAI

Why It Matters

A high-severity local privilege escalation vulnerability in RATOC RAID Monitoring Manager for Windows could allow non-administrative users to gain SYSTEM-level access on affected systems. Organizations using custom installation paths are at elevated risk, as the vulnerability enables arbitrary code execution with the highest system privileges. This poses a significant threat to data integrity and system security, particularly for organizations relying on RAID storage infrastructure.

Business Impact: High
Compensating Controls

Implement restrictive NTFS ACLs on RATOC installation directories to deny modify/write permissions for non-administrative users; disable RATOC services if not actively required; enforce application whitelisting to prevent unauthorized code execution; segment systems running RATOC from user workstations and critical infrastructure; increase logging and alerting on process creation and file system modifications within the RATOC directory; monitor for privilege escalation attempts; consider uninstalling RATOC from systems with custom installation paths until remediation is available.

Attack Technique

Privilege escalation occurs when an attacker leverages flaws in access control mechanisms to gain permissions beyond what they were originally granted.

Remote Code Execution represents the critical moment when an attacker successfully runs arbitrary code on a target system without physical access.
