# Vulnerability: Multiple Vulnerabilities in Dell Enterprise Management Solutions
## CVE Details
*Note: While the summary advisory (AV26-788) lists the affected products, specific CVE IDs are contained within the individual DSA links. Based on the advisory types provided:*
- **CVE ID:** Multiple (Refer to DSA-2026-335, DSA-2026-326, DSA-2026-325)
- **CVSS Score:** Not explicitly listed in the summary (Typically High/Critical for these product categories)
- **CWE:** Network Access Vulnerabilities; Multiple Vulnerabilities
## Affected Systems
- **Products:**
- Dell OpenManage Server Administrator (OMSA) Managed Node (Windows, RHEL 8.10, RHEL 9.4, SLES 15)
- RVTools
- Virtual Storage Integrator (VSI) for VMware vSphere Client
- **Versions:**
- OMSA Managed Node: All versions prior to 11.1.0.2
- RVTools: All versions prior to 4.8.1
- Virtual Storage Integrator: All versions prior to 10.11.1.0
- **Configurations:** Systems running OMSA with active network access and vSphere environments utilizing the VSI plugin.
## Vulnerability Description
The advisory covers three distinct security updates:
1. **OMSA Network Access Vulnerabilities:** Security flaws in the OpenManage Server Administrator that could allow unauthorized network-based access or manipulation.
2. **Virtual Storage Integrator (VSI) Vulnerabilities:** Multiple security flaws within the vSphere Client plugin used for managing Dell storage.
3. **RVTools Vulnerability:** A security flaw in the inventory and reporting tool used for VMware environments.
## Exploitation
- **Status:** Not explicitly reported as exploited in the wild (refer to vendor logs for zero-day status).
- **Complexity:** Medium (Typical for enterprise management software).
- **Attack Vector:** Network (Remote exploitation is the primary concern for OMSA and VSI).
## Impact
- **Confidentiality:** High (Potential access to infrastructure inventory and credentials).
- **Integrity:** High (Potential unauthorized modification of server or storage configurations).
- **Availability:** Medium to High (Potential for service disruption).
## Remediation
### Patches
Dell recommends upgrading to the following versions or later:
- **Dell OpenManage Server Administrator:** Version 11.1.0.2
- **RVTools:** Version 4.8.1
- **Virtual Storage Integrator for VMware vSphere:** Version 10.11.1.0
### Workarounds
- Restrict network access to OMSA web interfaces using firewalls or ACLs.
- Disable unused management plugins in vSphere if not actively required.
- Ensure the principle of least privilege is applied to service accounts used by these tools.
## Detection
- **Indicators of Compromise:** Monitor for unusual administrative logins or unauthorized configuration changes in Dell storage/server management consoles.
- **Detection methods and tools:** Vulnerability scanners should be updated with the latest plugins to detect outdated versions of OMSA and VSI plugins.
