CVE-2020-2038: PAN-OS management interface OS command injection

Automated analysis

Generated by VULONE's analysis model from the NVD record, CISA KEV and EPSS data on 18 September 2026. Confidence: high.

high priorityRoot-level command execution on a security control plane with public exploit code and very high EPSS, though it requires authenticated admin access.

What it is

The PAN-OS management interface contains an OS command injection flaw (CWE-78) that lets an authenticated administrator run arbitrary OS commands as root. It affects PAN-OS 9.0 before 9.0.10, 9.1 before 9.1.4, and 10.0 before 10.0.1. Because the management interface is a high-value control plane, successful abuse gives full root control of the firewall.

Impact

An attacker with administrative access gains root-level command execution on the firewall, enabling full compromise of the device, its configuration, and potentially the network it protects.

Attack surface

Reached over the network through the PAN-OS management interface (AV:N) with no user interaction (UI:N), but it requires high privileges (PR:H), meaning a valid administrator account is needed.

Exploitation

Not listed in CISA KEV, but public exploit code exists per Packet Storm references and EPSS is very high (0.86086, 99.7th percentile), indicating elevated likelihood of exploitation.

What to do

• Upgrade to PAN-OS 9.0.10, 9.1.4, 10.0.1 or later as the primary fix.
• Restrict management interface access to trusted administrative networks and disable it on untrusted interfaces.
• Enforce least privilege and strong authentication for administrator accounts, and audit who holds admin rights.
• Monitor and alert on unexpected OS-level command execution or configuration changes on PAN-OS devices.

Detection

• Review PAN-OS management interface logs for anomalous administrative sessions and command activity.
• Alert on unexpected processes or shell activity on the firewall host.
• Correlate admin logins with configuration changes or outbound connections from the management plane.
• Hunt for known public exploit patterns against the management interface in web/proxy logs.
