## What is CVE-2024-9472?

CVE-2024-9472 is a high-severity vulnerability in Palo Alto Networks Cloud NGFW, published on 14 Nov 2024. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

A null pointer dereference in Palo Alto Networks PAN-OS software on PA-800 Series, PA-3200 Series, PA-5200 Series, and PA-7000 Series hardware platforms when Decryption policy is enabled allows an unauthenticated attacker to crash PAN-OS by sending specific traffic through the data plane, resulting in a denial of service (DoS) condition. Repeated attempts to trigger this condition will result in PAN-OS entering maintenance mode.

Palo Alto Networks VM-Series, Cloud NGFW, and Prisma Access are not affected.

This issue only affects PA-800 Series, PA-3200 Series, PA-5200 Series, and PA-7000 Series running these specific versions of PAN-OS:

  *  10.2.7-h12
  *  10.2.8-h10
  *  10.2.9-h9
  *  10.2.9-h11

Check this codebase for CVE-2024-9472 and fix it if it is affected.

What it is: CVE-2024-9472 is a high-severity vulnerability in Palo Alto Networks Cloud NGFW, published on 14 Nov 2024. An attacker can exploit it over the internet without logging in, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2024-9472 in the wild and no public exploit code.

Affected product: Palo Alto Networks Cloud NGFW. No package-level version data is available, so check the vendor advisory linked from the reference page.

Task:
1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.
2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.
3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.
4. Run the tests and summarise what changed and why.
5. If nothing in the project is affected, say so and change nothing.
