Multiple denial of service (DoS) vulnerabilities exist in Palo Alto Networks PAN-OS software that allow an unauthenticated attacker with network access to cause a DoS condition by sending specially crafted network traffic to or through a dataplane interface. Repeated exploitation can cause the firewall to enter maintenance mode. Panorama management software is not affected by these vulnerabilities.
AI Analysis
Technical Summary
CVE-2026-0287 describes multiple denial of service vulnerabilities in Palo Alto Networks PAN-OS software. An unauthenticated attacker with network access can send specially crafted network traffic targeting the dataplane interface, causing the firewall to enter a denial of service state. Repeated attempts can cause the device to enter maintenance mode, impacting availability. The vulnerabilities do not affect Panorama management software. No specific affected versions or patch information is provided in the available data.
Potential Impact
The vulnerabilities allow unauthenticated remote attackers to cause a denial of service condition on affected PAN-OS firewalls, resulting in loss of availability. The firewall may enter maintenance mode, potentially disrupting network security operations. There is no impact on confidentiality or integrity reported. Panorama management software is not impacted.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Since no patch or official fix information is provided, users should monitor Palo Alto Networks advisories for updates. Until a fix is available, consider limiting network access to the dataplane interface from untrusted sources to reduce exposure.
