A missing integrity verification vulnerability in the Windows client software for ClearPass Policy Manager could allow malicious users on a local instance to elevate their user privileges. A successful exploit could allow these users to execute attacker-supplied code with elevated privileges on the local system.

AnalysisAI
Local privilege escalation in the HPE Aruba ClearPass Policy Manager Windows client software (CVSS 7.8, High) allows an attacker who already holds a low-privileged account on an affected Windows host to run attacker-supplied code with elevated privileges. The flaw is a missing integrity verification weakness: a file or component consumed by the client is loaded or executed with high privileges without being validated first, so an authenticated local user (PR:L, AV:L, UI:N per the assessed vector) can substitute a crafted component and gain SYSTEM-level execution. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires the attacker to already be an authenticated local user (PR:L) on a Windows system where the HPE Aruba ClearPass Policy Manager Windows client software is installed and running. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | This is a local privilege escalation flaw (CVSS 7.8/High) in the Windows client software for HPE Aruba ClearPass Policy Manager, stemming from missing integrity verification (CWE-345/CWE-494-class weakness). … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Apply the fixed ClearPass Policy Manager Windows client release identified in HPE Security Bulletin hpesbnw05158en_us (https://support.hpe.com/hpesc/public/docDisplay?docId=hpesbnw05158en_us&docLocale=en_US); no specific patched version number, GitHub commit, or PR is present in the provided data, and CVE-2026-79807 carries no CISA KEV listing, so patch status is best described as available through the vendor advisory rather than an independently confirmed tagged release - verify the exact build with HPE before deployment. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours: inventory all Windows hosts with the HPE Aruba ClearPass Policy Manager Windows client installed and cross-reference HPE bulletin hpesbnw05158en_us to identify affected versions; restrict local interactive logon to trusted users and remove unnecessary local administrator rights. …
