IQ Engine before 10.6r1 on Extreme Network AP devices has a Buffer Overflow in the implementation of the CAPWAP protocol that may be exploited to obtain elevated privileges to conduct remote code execution. Access to the internal management interface/subnet is required to conduct the exploit.

Security readout for executives and security teams

Plain-English summary

CVE-2023-35802 affects IQ Engine before 10.6r1 on Extreme Network AP devices. A buffer overflow in CAPWAP could let an attacker with access to the internal management interface or subnet gain elevated privileges and potentially run code remotely.

Executive priority

Treat this as high priority where vulnerable AP management networks are broadly reachable. It is not confirmed as actively exploited in the supplied evidence, but the potential impact includes elevated privileges and remote code execution on network infrastructure.

Technical view

The CVE describes a CAPWAP implementation buffer overflow in IQ Engine versions before 10.6r1. Exploitation requires access to the internal management interface/subnet and may lead to privilege escalation and remote code execution. The bundle provides no CVSS, CWE, proof-of-concept status, or detailed affected model list.

Likely exposure

Exposure is most likely in organizations running Extreme Network AP devices with IQ Engine earlier than 10.6r1, especially where management networks are reachable by broad internal user segments, vendors, or compromised hosts.

Exploitation context

The provided sources do not show CISA KEV listing or active exploitation. The key limiting factor is required access to the internal management interface/subnet, so risk depends heavily on network segmentation and administrative-plane exposure.

Researcher notes

Evidence is limited. The CVE description identifies IQ Engine before 10.6r1 and CAPWAP buffer overflow behavior, but the bundle lacks CVSS, CWE, model granularity, exploit maturity, and detailed patch notes. Avoid assuming Internet exposure because internal management access is explicitly required.

Mitigation direction

  • Review Extreme advisory 000112741 for supported remediation guidance.
  • Upgrade affected IQ Engine deployments to 10.6r1 or a later vendor-supported fixed release.
  • Restrict access to AP management interfaces and subnets to trusted administrators only.
  • Monitor management networks for unusual CAPWAP or administrative-plane activity.

Validation and detection

  • Inventory Extreme Network AP devices and record IQ Engine versions.
  • Flag any IQ Engine version earlier than 10.6r1 for remediation review.
  • Confirm management interfaces are not reachable from untrusted internal networks.
  • Check vendor advisory details against deployed AP models and support status.
