AI Powered Q&A
Can you explain this vulnerability to me?
This vulnerability occurs on Arista EOS platforms when MACsec and egress ACLs are configured on the same interfaces. Due to this issue, the ACL policies may not be properly enforced on outgoing packets, meaning that packets leaving the affected ports might be incorrectly allowed or denied.
How can this vulnerability impact me? :
The impact of this vulnerability is that network security policies enforced by egress ACLs may not function correctly. This can lead to unauthorized data being sent out or legitimate data being blocked, potentially causing security breaches or disruptions in network communication.
