Vulnerability in Vlan Protocol
CVE-2005-4440
The 802.1q VLAN protocol allows remote attackers to bypass network segmentation and spoof VLAN traffic via a message with two 802.1q tags, which causes the second tag to be redirected from a downstream switch after the first tag has been stripped, as demonstrated by Yersinia, aka "double-tagging VLAN jumping attack."
EPSS: 0.016 (73.5th percentile) — read the EPSS interpretation.
