CVE-2022-45112
📋 TL;DR
This vulnerability in Intel VROC software allows authenticated users with local access to potentially escalate privileges due to improper access control. It affects systems running vulnerable versions of Intel VROC software, primarily impacting enterprise servers with Intel RAID configurations.
💻 Affected Systems
- Intel Virtual RAID on CPU (VROC) software
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
An authenticated attacker could gain full administrative control over the system, potentially compromising the entire server and accessing sensitive data.
Likely Case
A malicious insider or compromised account could elevate privileges to gain unauthorized access to system resources and configuration settings.
If Mitigated
With proper access controls and monitoring, impact is limited to authorized users who would need to bypass additional security layers.
🎯 Exploit Status
Requires authenticated local access but the access control bypass appears straightforward once authenticated.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 8.0.0.4035 or later
Vendor Advisory: http://www.intel.com/content/www/us/en/security-center/advisory/intel-sa-00846.html
Restart Required: Yes
Instructions:
1. Download Intel VROC version 8.0.0.4035 or later from Intel's website. 2. Stop any RAID operations. 3. Install the update following Intel's installation guide. 4. Reboot the system.
🔧 Temporary Workarounds
Restrict local access
allLimit local console and remote desktop access to only necessary administrative personnel
Implement privilege separation
allEnsure users with local access do not have unnecessary permissions that could be leveraged
🧯 If You Can't Patch
- Implement strict access controls and monitor for privilege escalation attempts
- Isolate affected systems from critical network segments and implement additional authentication layers
🔍 How to Verify
Check if Vulnerable:
Check Intel VROC software version via Intel RAID Web Console or command line interfaceCheck Version:
On Linux: 'rpm -qa | grep vroc' or 'dpkg -l | grep vroc'. On Windows: Check Programs and Features or use 'wmic product get name,version'Verify Fix Applied:
Verify installed version is 8.0.0.4035 or higher and test privilege escalation attempts fail📡 Detection & Monitoring
Log Indicators:
- Failed or successful privilege escalation attempts in system logs
- Unauthorized access to VROC management functions
Network Indicators:
- Unusual local authentication patterns followed by administrative actions
