AI-Generated

An authenticated supplicant on an adjacent network can exploit a timing window between authentication and the enforcement of access control lists (ACLs) to send unrestricted traffic. This vulnerability poses a low risk, but it could allow unauthorized data transmission during the brief period of ACL enforcement delay. Network administrators and security teams should prioritize monitoring and mitigating this issue to prevent potential unauthorized access or data leakage.
