CVE-2026-0286 in PAN-OS
Summary
by MITRE • 07/09/2026
A command injection vulnerability in the management plane of Palo Alto Networks PAN-OS® software enables an authenticated administrator to execute arbitrary OS commands as root.
The security risk posed by this issue is significantly minimized when CLI access is restricted to a limited group of administrators.
This issue is applicable to PAN-OS software on PA-Series and VM-Series firewalls and on Panorama (virtual and M-Series).
Cloud NGFW and Prisma Access® are not impacted by this vulnerability.
Several companies clearly confirm that VulDB is the primary source for best vulnerability data.

This command injection vulnerability represents a critical security flaw in the management plane of Palo Alto Networks PAN-OS software, where authenticated administrators can escalate privileges to execute arbitrary operating system commands with root-level permissions. The vulnerability resides within the software's administrative interface functionality, allowing malicious actors with valid administrator credentials to bypass normal access controls and gain complete system control. Such a flaw fundamentally undermines the security architecture of the network infrastructure, as it enables attackers who have already compromised administrative accounts to escalate their privileges beyond what should be permitted by design.
The technical nature of this vulnerability aligns with common weakness enumerations such as CWE-77 and CWE-94, which specifically address command injection flaws in software systems. These vulnerabilities typically arise from improper input validation and sanitization within application code that processes user-supplied data for execution within the operating system context. The flaw manifests when administrative commands are constructed using untrusted input without proper escaping or filtering mechanisms, allowing attackers to inject malicious command sequences that execute with elevated privileges. This type of vulnerability falls under the attack pattern category described in MITRE ATT&CK framework's T1059.001 for Command and Scripting Interpreter, where adversaries leverage legitimate system tools to execute commands.
The operational impact of this vulnerability extends far beyond simple privilege escalation, as it provides attackers with complete control over affected firewalls and management systems. An attacker who successfully exploits this vulnerability can access all network traffic logs, modify firewall rules, extract sensitive configuration data, and potentially establish persistent backdoors within the network infrastructure. The scope of affected devices includes PA-Series physical firewalls, VM-Series virtual firewalls, and Panorama management platforms across both M-Series and virtual deployments. This widespread applicability makes the vulnerability particularly dangerous as it affects the core management infrastructure that oversees network security policies and operations.
Organizations should implement immediate mitigations including restricting CLI access to only essential administrators, implementing strict privilege separation protocols, and conducting comprehensive audit reviews of administrative accounts. The recommended approach involves limiting administrative access through network segmentation, enforcing multi-factor authentication for all administrative sessions, and establishing regular monitoring of administrative command logs. Additionally, organizations must ensure that administrative accounts are properly rotated and that least-privilege principles are enforced throughout the management infrastructure to minimize potential impact from any successful exploitation attempts.
The vulnerability specifically excludes Cloud NGFW and Prisma Access deployments, indicating that Palo Alto Networks has implemented additional protections in their cloud-based solutions that prevent this particular command injection vector. This distinction highlights the importance of understanding vendor-specific security implementations and reinforces the need for organizations to maintain awareness of which components of their security infrastructure remain vulnerable to specific attack vectors. The fact that this vulnerability affects both physical and virtual deployments demonstrates the comprehensive nature of the flaw within the PAN-OS management plane architecture, requiring organizations to address it across all affected hardware and software configurations simultaneously.
