Security readout for executives and security teams
CVE-2019-0033 affects Juniper SRX firewalls running certain Junos OS releases when proxy ARP is configured. A remote unauthenticated attacker could drive high CPU and cause denial of service. The issue is IPv4-only and primarily creates an availability risk for perimeter or routed firewall services. Exposure is limited to Juniper SRX Series devices on affected Junos OS trains with proxy ARP configured for IPv4. Listed affected ranges include 12.1X46 before D71 except D73 context noted, 12.3X48 before D50, and 15.1X49 before D75. Prioritize remediation for internet-facing or high-traffic SRX firewalls using proxy ARP, especially where downtime would disrupt branch, VPN, or perimeter connectivity. This is not a data-theft issue in the supplied sources, but it can affect service availability. Mitigation focus: Inventory SRX devices and Junos OS versions against Juniper JSA10922.; Upgrade affected releases to vendor-listed fixed or later supported releases.; Review whether proxy ARP is required on exposed IPv4 interfaces..
