CVE-2024-42396
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 · uneditedMultiple unauthenticated Denial-of-Service (DoS) vulnerabilities exist in the AP Certificate Management daemon accessed via the PAPI protocol. Successful exploitation of these vulnerabilities results in the ability to interrupt the normal operation of the affected Access Point.
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 confidenceMultiple unauthenticated DoS vulnerabilities exist in the Access Point Certificate Management daemon accessed via the PAPI protocol. Attackers can exploit these vulnerabilities without authentication to crash or make the AP Certificate Management service unavailable, disrupting normal Access Point operation.

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 the InstantOS versionRun 'show version' or check the system firmware version through the AP management interfaceAffected if The displayed version falls within 8.10.0.0-8.10.0.12 or 8.12.0.0-8.12.0.1
-
Confirm InstantOS productVerify the device is running Hp InstantOS by checking the system information or boot logsAffected if The product is confirmed as Hp InstantOS and the version meets the affected range criteria
-
Verify PAPI protocol service availabilityCheck if the PAPI (Protocol Access Point Interface) service is running and reachable on the AP Certificate Management daemonAffected if The PAPI service is exposed and accessible on the network without authentication
You are affected if your Hp InstantOS version is 8.10.0.0-8.10.0.12 or 8.12.0.0-8.12.0.1 AND the AP Certificate Management daemon via PAPI protocol is accessible on your network.
Generated from the published advisory. Verify against your own configuration.
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.
dbcve · scoped8.10.0.138.12.0.2
Apply vendor-provided patches for the AP Certificate Management daemon. If no patch is available, consider network segmentation to limit PAPI protocol exposure and implement rate limiting on the affected service to mitigate DoS attempts.
InstantOS 8.12.0.2 (or 8.10.0.13 for 8.10.x branch)
- Identify the currently installed InstantOS version on the affected Access Points
- For InstantOS 8.10.x: Upgrade to version 8.10.0.13 or later
- For InstantOS 8.12.x: Upgrade to version 8.12.0.2 or later
- Deploy the upgrade through the Aruba Instant UI or controller-based deployment method
- Verify the upgrade was successful and the AP Certificate Management daemon is functioning normally
