CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:L/A:NOn affected platforms running Arista EOS where a tunnel decapsulation configuration—such as VXLAN (Virtual Extensible LAN), decap-groups, or a GRE (Generic Routing Encapsulation) tunnel interface—is present, the switch will incorrectly decapsulate and forward other unexpected tunneled packet with a destination IP matching its configured decapsulation IP. This occurs because the switch does not verify the tunnel protocol type, potentially leading to the unexpected processing of non-configured tunnel traffic. This issue has been reported as being exploited in the wild.
CISA has added three newly exploited vulnerabilities to its KEV catalog, impacting Cisco, Google Chrome, and Arista Networks. These vulnerabilities – one in Cisco SD-WAN Manager, another in Chrome’s V8 engine, and a thir…
Organizations are advised to apply vendor-supplied mitigations or discontinue the vulnerable devices. The post No Patch Planned for Exploited Arista EOS Vulnerability appeared first on SecurityWeek .
