VAR-202509-4014

Vulnerability from variot - Updated: 2025-11-28 23:25

A vulnerability in the access control list (ACL) processing of IPv4 packets of Cisco SD-WAN vEdge Software could allow an unauthenticated, remote attacker to bypass a configured ACL.

This vulnerability is due to the improper enforcement of the implicit deny all at the end of a configured ACL. An attacker could exploit this vulnerability by attempting to send unauthorized traffic to an interface on an affected device. A successful exploit could allow the attacker to bypass an ACL on the affected device. Cisco SD-WAN vEdge is a router manufactured by Cisco Systems, Inc
