CVE-2024-31481
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 · uneditedUnauthenticated Denial of Service (DoS) vulnerabilities exist in the CLI service accessed via the PAPI protocol. Successful exploitation of these vulnerabilities result in the ability to interrupt the normal operation of the affected service.
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 confidenceThis is an unauthenticated Denial of Service vulnerability affecting the CLI service when accessed through the PAPI protocol. An attacker can exploit this vulnerability without any credentials to disrupt normal service operations, likely by sending specially crafted requests to the PAPI interface.

Affected products & versions What the vendor confirmedThe version ranges the vendor confirmed as vulnerable. If your version sits inside a range here, treat yourself as exposed until you have upgraded.

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 product and versionRun the command to display the system version. On ArubaOS, typically use 'show version' or check the controller web interface under Maintenance > Software. On InstantOS, use 'show version' or check the Instant AP web interface.Affected if The installed version falls within the affected ranges: ArubaOS >= 10.3.0.0 and < 10.4.1.1, or >= 10.5.0.0 and < 10.5.1.1; InstantOS >= 6.4.0.0 and < 8.6.0.24, or >= 8.7.0.0 and < 8.10.0.11
-
Verify PAPI protocol is enabledCheck the controller or Instant AP configuration for PAPI protocol settings. This is typically found in the CLI service configuration or security settings. Look for entries related to 'PAPI' or 'Platform Abstraction Protocol' in the running configuration.Affected if PAPI protocol is enabled and accessible on the device, making the CLI service reachable through this interface
-
Confirm network exposure of PAPI serviceVerify which network interfaces and IP addresses the PAPI service is bound to. Check if PAPI listens on management, control, or data plane interfaces. Use commands like 'show ip interface' or check the service listener status.Affected if PAPI service is bound to any IP address that is reachable from untrusted networks, rather than being isolated to internal management networks only
-
Check for DoS symptoms or service disruption logsReview system logs, particularly those related to CLI access and PAPI protocol. Look for patterns of service restarts, connection failures, or unexpected CLI/PAPI errors around the time of potential exploitation.Affected if The CLI service or PAPI protocol shows repeated crashes, restarts, or unusual error patterns indicating a DoS condition
A user is affected if their ArubaOS or InstantOS version is within the vulnerable ranges AND the PAPI protocol is enabled and accessible on the network.

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 · scoped8.6.0.248.10.0.1110.4.1.1
Implement network segmentation to restrict access to the CLI/PAPI service, apply rate limiting on the PAPI interface, and apply vendor-supplied patches when available.
ArubaOS: 10.4.1.1 or 10.5.1.1 | InstantOS: 8.6.0.24 or 8.10.0.11
- 1. Back up the current device configuration to a secure location
- 2. Download the appropriate fixed firmware version from the official Aruba support portal (support.hpe.com or www.arubanetworks.com)
- 3. For ArubaOS: Upgrade to version 10.4.1.1 (if on 10.3.x branch) or 10.5.1.1 (if on 10.5.x branch)
- 4. For InstantOS: Upgrade to version 8.6.0.24 (if on 6.4.x-8.5.x branch) or 8.10.0.11 (if on 8.7.x-8.9.x branch)
- 5. Follow standard Aruba upgrade procedures - upload firmware via WebUI or CLI, then reboot the device
- 6. After reboot, verify the device is operational and the vulnerability is resolved
- 7. Restore configuration from backup if needed and verify all services are functioning normally
