CVE-2026-73787

Authenticated Arbitrary File Write allows Remote Code Execution via CPPM Web Interface

Published Sep 9, 2026 CVSS 3.1 · 7.2 High EPSS < 1% KEV · Not listed
Description
A vulnerability in the CPPM web interface could allow an authenticated remote attacker to access directory information on a vulnerable system. Successful exploitation could allow an attacker to execute arbitrary commands on the underlying operating system.

Analysis

AI-generated

Technical impact

An authenticated attacker who can access the ClearPass Policy Manager web interface can read directory information and execute arbitrary commands on the underlying operating system. This allows full compromise of the host with unrestricted execution of malicious code. The weakness involves OS command injection (CWE-78).

Affected Systems

Hewlett Packard Enterprise’s ClearPass Policy Manager (CPPM) is affected. No specific version ranges are listed, implying that all current releases remain vulnerable until the vendor releases a fix.

Risk and Exploitability

The CVSS score of 7.2 indicates high severity, and the EPSS score of less than 1% suggests a low probability of exploitation in the near term. Because authentication is required, attackers must have valid credentials, which many administrators provide. Although it is not listed in CISA’s KEV catalog, the potential for remote code execution makes it a high‑priority target for remediation.

Remediation

No solution or workaround provided in the CVE record.

OpenCVE Recommended Actions

  • Download and apply the vendor‑provided security update for ClearPass Policy Manager that addressed the directory access and command execution flaw.
  • Restrict web interface access to a minimal, trusted set of administrators and enforce least‑privilege principles to monitor logs and network traffic for unusual command execution attempts, and configure alerts for suspicious behavior.
  • Implement network segmentation or firewall rules to isolate the ClearPass server from untrusted networks, limiting the attack surface exposed to authenticated users.
