CVE-2022-23689: Multiple vulnerabilities exist in the processing of packet data by the LLDP service of AOS-CX.

Multiple vulnerabilities exist in the processing of packet data by the LLDP service of AOS-CX. Successful exploitation of these vulnerabilities may allow an attacker to impact the availability of the AOS-CX LLDP service and/or the management plane of the switch in ArubaOS-CX Switches version(s): AOS-CX 10.09.xxxx: 10.09.1010 and below, AOS-CX 10.08.xxxx: 10.08.1050 and below, AOS-CX 10.06.xxxx: 10.06.0190 and below. Aruba has released upgrades for ArubaOS-CX Switch Devices that address these security vulnerabilities.

Security readout for executives and security teams

Plain-English summary

This vulnerability affects Aruba AOS-CX switches. Malformed LLDP packet processing can disrupt the LLDP service and potentially the switch management plane. It is not described as data theft or remote takeover, but management-plane availability issues can affect network operations.

Executive priority

Treat as a maintenance-priority network availability issue. It should be patched through normal network change control, with faster handling for core or management-critical switches.

Technical view

CVE-2022-23689 covers multiple LLDP packet-processing flaws in ArubaOS-CX. The CVSS vector is adjacent-network, low complexity, no privileges, no user interaction, with low availability impact and no confidentiality or integrity impact. Aruba released AOS-CX upgrades addressing the issue.

Likely exposure

Exposure is limited to affected ArubaOS-CX switch versions: 10.09.1010 and below, 10.08.1050 and below, and 10.06.0190 and below on listed Aruba CX switch series.

Exploitation context

The source bundle does not show CISA KEV listing or public active exploitation. CVSS indicates an attacker must be adjacent to the network path that can interact with LLDP processing.

Researcher notes

Sources do not provide CWE mapping, packet details, or exploit evidence. Keep assessment bounded to LLDP processing availability impact and vendor upgrade remediation.

Mitigation direction

  • Inventory ArubaOS-CX switches and record exact software versions.
  • Upgrade affected devices using Aruba's advisory guidance.
  • Prioritize switches supporting critical network segments or remote management workflows.
  • Check Aruba guidance for fixed release targets and deployment constraints.
  • Monitor for LLDP service or management-plane availability disruptions.

Validation and detection

  • Compare running AOS-CX versions against the vulnerable version thresholds.
  • Confirm affected switch series are included in the advisory scope.
  • Verify upgraded devices report a non-vulnerable ArubaOS-CX release.
  • Review logs for unexplained LLDP or management-plane instability.
  • Document any devices awaiting upgrade and compensating controls.
