A brief (milliseconds to seconds) traffic leak may occur when an authenticated supplicant is removed, either via the clear dot1x host all CLI command or due to a supplicant timeout. During this window, the supplicant's traffic may pass without ACL enforcement.

Why it matters

Internet-facing
Not identified as a common internet-facing category
Exploitation likelihood
medium
  • Exploitable from an adjacent network segment
  • High attack complexity — exploitation requires specific conditions
  • Requires low-privilege access first
  • No user interaction needed — can be exploited automatically
Recommended mitigation

Apply the vendor patch as soon as it's available or already released. Review and restrict accounts with the privilege level this vulnerability requires.

This analysis is generated from structured CVSS vector data, CISA KEV cross-referencing, and vendor/product category rules — not a manual expert review. Treat it as a starting point, not a substitute for your own assessment.
