CVE-2025-0110: High Vulnerability in Palo Alto Networks PAN-OS

CVE-2025-0110 represents a high-severity command injection vulnerability discovered in the Palo Alto Networks PAN-OS OpenConfig plugin. This vulnerability allows an authenticated administrator, capable of making gNMI requests to the PAN-OS management web interface, to bypass system restrictions and execute arbitrary commands. The commands are executed with the privileges of the '__openconfig' user, which possesses the Device Administrator role on the firewall. The potential impact of this vulnerability is significant, as it could lead to unauthorized access or manipulation of the firewall settings.

According to the CVSS score of 8.6, this vulnerability is classified as high severity. The scoring indicates an attack vector of NETWORK, low attack complexity, and a requirement for high privileges. Organizations using affected versions of PAN-OS should prioritize remediation efforts to mitigate risks associated with this vulnerability.

Risk to organizations includes potential unauthorized command execution that can lead to system disruption or data breaches. Given the high CVSS score and the impact of this vulnerability, organizations must address this vulnerability in their patch cycle. Immediate action is recommended to secure the affected systems.

Currently, there is no public exploit confirmed for this vulnerability, and it has not been listed as actively exploited in the Known Exploited Vulnerabilities (KEV) database. Nonetheless, the potential for exploitation remains high, underscoring the importance of timely remediation.

Organizations should prioritize patching immediately.

Vulnerability Details

The vulnerability is characterized as a command injection vulnerability in the Palo Alto Networks PAN-OS OpenConfig plugin. The official CVE description confirms that it enables an authenticated administrator to run arbitrary commands on the firewall through gNMI requests made to the management web interface. The commands executed are privileged, running as the '__openconfig' user.

The CVSS score of 8.6 signifies a high severity level, indicating a significant risk to confidentiality, integrity, and availability of the system. The vulnerability has a CWE classification of CWE-78.

This vulnerability was published on February 12, 2025, and remains in a deferred status. Organizations using PAN-OS should consult the vendor's guidance for specific remediation steps.

Technical Analysis

The root cause of this vulnerability lies in inadequate validation of user inputs in the PAN-OS OpenConfig plugin, allowing malicious commands to be injected and executed by the firewall as the '__openconfig' user.

The attack vector is network-based, requiring an attacker to have authenticated access to the management web interface. The attack complexity is low, as it does not require a sophisticated technique, and high privileges are needed to execute the arbitrary commands.

User interaction is not required for this vulnerability to be exploited. If successful, the attacker can compromise confidentiality, integrity, and availability, leading to a complete takeover of the firewall.

Risk & Impact Analysis

Real-world deployment risk includes the potential for attackers to gain administrative control over the firewall, leading to unauthorized access to sensitive data and configurations. This vulnerability's high CVSS score reflects the serious implications for organizations, particularly those with critical infrastructure relying on PAN-OS.

The urgency for organizations to patch this vulnerability is high, as the potential blast radius could impact the entire network. Organizations should prioritize remediation as part of their critical patch management processes.

Exploitation Status

Affected Versions

Specific version information is not available. Organizations are advised to consider all versions prior to vendor patch as affected.

Mitigation & Remediation

To mitigate this vulnerability, it is recommended that organizations restrict access to the management web interface to only trusted internal IP addresses. This can significantly reduce the risk of exploitation.

Organizations should also ensure they are running the latest version of PAN-OS. For more information on securing management access, please refer to the best practices deployment guidelines outlined in the vendor's recommendations.

For comprehensive assessment and security validation, organizations may consider engaging in penetration testing services tailored to their environment.

Detection Guidance

To detect potential exploitation of this vulnerability, organizations should monitor logs for unusual command executions and access attempts to the management web interface. Behavioral anomalies indicative of unauthorized access should also be flagged for further investigation.

Additionally, network signatures for known gNMI requests should be established to identify unauthorized attempts to interact with the firewall's management interface.
