Researcher discovered vulnerabilities in Layer-2 managed switches

A researcher has found vulnerabilities in network security techniques at the Layer-2 level. The vulnerabilities reside in the fact that the QinQ functionality IEEE 802.1ad standard incorrectly allows VLAN 0 priority tag and 802.2 LLC/SNAP headers can be stacked multiple define VLANs within VLANs....

L2 network security controls can be bypassed using VLAN 0 stacking and/or 802.3 headers

Overview Layer-2 L2 network security controls provided by various devices, such as switches, routers, and operating systems, can be bypassed by stacking Ethernet protocol headers. An attacker can send crafted packets through vulnerable devices to cause Denial-of-service DoS or to perform a...
