Name of the Vulnerable Software and Affected Versions Istio versions through 1.28.2

Description Istio versions through 1.28.2 permit the injection of iptables rules, potentially altering firewall behavior. This is achieved through the traffic.sidecar.istio.io/excludeInterfaces annotation. The reporter notes that this may not represent a security issue, as pod creators can already prevent sidecar injection.
