# Vulnerability: HPE iLO 7 User Validation Failure
## CVE Details
- **CVE ID:** CVE-2026-38241 (Note: Based on the bulletin reference HPESBHF05163)
- **CVSS Score:** 7.5 (High)
- **CWE:** CWE-287 (Improper Authentication) / User Validation Failure
## Affected Systems
- **Products:** HPE Integrated Lights-Out 7 (iLO 7)
- **Versions:** All versions prior to v1.25.00
- **Configurations:** Systems using COM (Component Object Model) interfaces for management.
## Vulnerability Description
A vulnerability exists in HPE iLO 7 where the system fails to properly validate user sessions or credentials when accessed via specific COM interfaces. This flaw could allow an attacker to bypass standard authentication mechanisms or escalate privileges within the iLO management environment.
## Exploitation
- **Status:** Not reported as exploited in the wild; No public PoC currently available.
- **Complexity:** Medium
- **Attack Vector:** Network (Remote)
## Impact
- **Confidentiality:** High (Potential unauthorized access to management data)
- **Integrity:** High (Potential unauthorized modification of system settings)
- **Availability:** Low (Potential for service disruption via unauthorized configuration changes)
## Remediation
### Patches
HPE recommends updating to the following firmware version or later:
- **HPE iLO 7 v1.25.00**
### Workarounds
- Restrict access to iLO management networks to trusted administrative traffic only.
- Disable unnecessary management protocols/interfaces if not in use.
- Implement strong network segmentation (VLANs) to isolate the iLO management processor from the production network.
## Detection
- **Indicators of Compromise:** Review iLO event logs for unusual login activity or unauthorized configuration changes originating from unexpected IP addresses.
- **Detection methods and tools:** Use vulnerability scanners to identify iLO instances running firmware versions earlier than 1.25.00.
