- CVE-2021-4477Critical
Hirschmann HiLCOS OpenBAT and BAT450 products contain a firewall bypass vulnerability in IPv6 IPsec deployments. Traffic from VPN connections can bypass configured firewall rules. Attackers can exploit this by establishing IPv6 IPsec connections (IKEv1 or IKEv2) while using an IPv6 Internet connection to circumvent firewall policy enforcement.
- CVE-2017-20233Medium
Hirschmann HiLCOS products (OpenBAT, BAT450, WLC, BAT867) have a firewall filtering vulnerability that fails to correctly filter IPv4 multicast and broadcast traffic when management IP address filtering is disabled, allowing configured filter rules to be bypassed.
- CVE-2015-10148High
Hirschmann HiLCOS devices (OpenBAT, WLC, BAT300, BAT54) before version 8.80 and OpenBAT before 9.10 are shipped with identical default SSH and SSL keys that cannot be changed. This allows unauthenticated remote attackers to decrypt or intercept encrypted management communications.
