CVE-2025-0130: PAN-OS: Firewall Denial-of-Service (DoS) in the Web-Proxy Feature via a Burst of Maliciously Crafted Packets
A missing exception check in Palo Alto Networks PAN-OS® software with the web proxy feature enabled allows an unauthenticated attacker to send a burst of maliciously crafted packets that causes the firewall to become unresponsive and eventually reboot. Repeated successful attempts to trigger this condition will cause the firewall to enter maintenance mode.
This issue does not affect Cloud NGFW or Prisma Access.
Security readout for executives and security teams
Plain-English summary
This flaw can let an unauthenticated remote attacker make affected Palo Alto Networks firewalls stop responding and reboot when the web-proxy feature is enabled. Repeated successful crashes can push the firewall into maintenance mode, creating a business-impacting outage risk. Cloud NGFW and Prisma Access are listed as unaffected.
Executive priority
Treat this as a high-priority availability risk for affected PAN-OS firewalls because successful attacks can interrupt security gateway operations. Prioritize exposed, web-proxy-enabled firewalls first. The sources do not support claims of active exploitation.
Technical view
CVE-2025-0130 is a PAN-OS missing exception check, classified as CWE-754. The attack vector is network-based, requires no privileges or user interaction, but has high attack complexity. Impact is availability-only: firewall unresponsiveness, reboot, and possible maintenance mode after repeated triggers.
Likely exposure
Exposure appears limited to Palo Alto Networks PAN-OS deployments in the listed 10.1, 10.2, 11.1, and 11.2 affected ranges where the web-proxy feature is enabled. Cloud NGFW and Prisma Access are not affected per the source bundle.
Exploitation context
The source bundle does not state active exploitation, and KEV is false. Publicly cited details describe a burst of maliciously crafted packets but do not provide exploit steps. The practical concern is service disruption against internet-reachable or untrusted-network-reachable firewall interfaces using web proxy.
Researcher notes
The available evidence supports availability impact only, with no confidentiality or integrity impact indicated by the CVSS vector. Attack complexity is high, but no authentication is required. Patch and workaround specifics are not included in the provided source bundle, so remediation should be tied to vendor guidance.
Mitigation direction
Check Palo Alto Networks advisory for fixed PAN-OS releases and branch-specific guidance.
Prioritize remediation for firewalls with web proxy enabled and untrusted network exposure.
Evaluate whether web proxy can be disabled where it is not operationally required.
Monitor firewall reboots, unresponsiveness, and maintenance-mode transitions for suspicious repetition.
Confirm Cloud NGFW and Prisma Access are excluded from remediation scope.
Validation and detection
Inventory PAN-OS versions across firewall fleets.
Identify which firewalls have the web-proxy feature enabled.
Map affected devices to network exposure from untrusted sources.
Review logs and uptime history for unexplained reboots or maintenance-mode entries.
Track remediation status against the Palo Alto Networks advisory.
