CVE-2025-0122
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedA denial-of-service (DoS) vulnerability in Palo Alto Networks Prisma® SD-WAN ION devices enables an unauthenticated attacker in a network adjacent to a Prisma SD-WAN ION device to disrupt the packet processing capabilities of the device by sending a burst of crafted packets to that device.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceA denial-of-service vulnerability in Palo Alto Networks Prisma SD-WAN ION devices allows an unauthenticated attacker on an adjacent network segment to send a burst of crafted packets that disrupt the device's packet processing capabilities. The vulnerability requires network proximity to the target device rather than remote exploitation.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify device typeLog into the Prisma SD-WAN controller or CLI and verify the device model is an ION device (e.g., ION 100, ION 1000, ION 3000, etc.)Affected if The device is a Palo Alto Networks Prisma SD-WAN ION appliance
-
Check installed software versionRun 'show version' in the device CLI or check via the Prisma SD-WAN web interface under Device > Setup > Operations to retrieve the installed ION software versionAffected if The installed version falls within the affected range (if known) or remains unpatched against CVE-2025-0122
-
Verify adjacent network exposureReview network configuration to determine if the ION device management or data interfaces are reachable from adjacent network segments (VLANs, directly connected networks, or Layer 2 neighbors)Affected if The device accepts traffic from adjacent network segments without proper segmentation or filtering
-
Check for packet processing issuesMonitor device statistics via 'show interface' and 'show system resources' commands, or review syslog/event logs for sudden spikes in dropped packets, CPU usage, or service disruptionsAffected if The device exhibits unexplained packet loss, high CPU, or processing failures that correlate with the described DoS condition
-
Review authentication statusConfirm the vulnerability is exploitable without authentication by verifying no external or adjacent-network authentication is required for the affected packet processing pathAffected if The device processes packets from unauthenticated sources on adjacent network segments
A user is affected if they operate a Prisma SD-WAN ION device that is exposed to adjacent network segments and is running a version vulnerable to CVE-2025-0122, as the flaw allows unauthenticated adjacent attackers to disrupt packet processing.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataApply the vendor-provided patch for Prisma SD-WAN ION devices when available; as an interim measure, implement network segmentation and filtering to restrict adjacent network access to trusted sources.
