Name of the Vulnerable Software and Affected Versions 802.1q VLAN protocol (affected versions not specified)

Description The issue allows remote attackers to bypass network segmentation and spoof VLAN traffic by sending a message with two 802.1q tags. This causes the second tag to be redirected from a downstream switch after the first tag has been stripped, as demonstrated by the "double-tagging VLAN jumping attack" using tools like Yersinia.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
