CVE-2022-2637

5.4 MEDIUM

📋 TL;DR

This vulnerability allows remote authenticated users to escalate their privileges in Hitachi Storage Plug-in for VMware vCenter. Attackers with existing authenticated access can gain higher privileges than intended. This affects organizations using the vulnerable versions of the Hitachi Storage Plug-in.

💻 Affected Systems

Products:
  • Hitachi Storage Plug-in for VMware vCenter
Versions: 04.8.0 through versions before 04.9.0
Operating Systems: VMware vCenter Server
Default Config Vulnerable: ⚠️ Yes
Notes: Requires the Hitachi Storage Plug-in to be installed and configured in vCenter.

📦 What is this software?

⚠️ Risk & Real-World Impact

🔴

Worst Case

An authenticated attacker gains administrative control over the storage plug-in, potentially compromising connected storage systems and vCenter infrastructure.

🟠

Likely Case

Authenticated users with limited privileges gain unauthorized access to storage management functions they shouldn't have.

🟢

If Mitigated

With proper access controls and network segmentation, impact is limited to the storage plug-in component only.

🌐 Internet-Facing: LOW (requires authenticated access and typically deployed in internal networks)
🏢 Internal Only: MEDIUM (requires authenticated access but could be exploited by malicious insiders or compromised accounts)

🎯 Exploit Status

Public PoC: ✅ No
Weaponized: UNKNOWN
Unauthenticated Exploit: ✅ No
Complexity: LOW

Exploitation requires authenticated access to the vCenter system where the plug-in is installed.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: 04.9.0 or later

Vendor Advisory: https://www.hitachi.com/products/it/software/security/info/vuls/hitachi-sec-2022-131/index.html

Restart Required: Yes

Instructions:

1. Download version 04.9.0 or later from Hitachi support portal. 2. Backup current configuration. 3. Install the updated plug-in package. 4. Restart vCenter services. 5. Verify functionality.

🔧 Temporary Workarounds

Restrict Access

all

Limit network access to vCenter systems and implement strict authentication controls

Principle of Least Privilege

all

Review and minimize user privileges in vCenter to reduce attack surface

🧯 If You Can't Patch

  • Implement strict access controls and monitor for unusual privilege escalation attempts
  • Segment vCenter and storage management networks to limit lateral movement

🔍 How to Verify

Check if Vulnerable:

Check the plug-in version in vCenter Client under Configure > Storage Providers > Hitachi Storage Plug-in

Check Version:

Check via vSphere Client or vCenter API for installed plug-in version

Verify Fix Applied:

Verify version is 04.9.0 or later in vCenter Client and test storage management functions

📡 Detection & Monitoring

Log Indicators:

  • Unusual privilege changes in vCenter logs
  • Multiple failed authentication attempts followed by successful privileged operations

Network Indicators:

  • Unusual API calls to storage management endpoints from non-admin accounts

SIEM Query:

source="vcenter" AND (event_type="privilege_escalation" OR user_role_change="storage_admin")
