WatchGuard Fireware v11.12.1 and earlier mishandles requests referring to an XML External Entity (XXE), in the XML-RPC agent. This causes the Firebox wgagent process to crash. This process crash ends all authenticated sessions to the Firebox, including management connections, and prevents new authenticated sessions until the process has recovered. The Firebox may also experience an overall degradation in performance while the wgagent process recovers. An attacker could continuously send XML-RPC requests that contain references to external entities to perform a limited Denial of Service (DoS) attack against an affected Firebox.

Security readout for executives and security teams

CVE-2017-8056 is a denial-of-service issue in WatchGuard Fireware v11.12.1 and earlier. Malformed XML-RPC requests using external entity references can crash the Firebox wgagent process, dropping authenticated sessions and temporarily blocking new management sessions while it recovers. Exposure is most relevant for organizations running WatchGuard Fireware v11.12.1 or earlier where the Firebox XML-RPC management path is reachable by untrusted or semi-trusted networks. Prioritize remediation for internet-exposed or broadly reachable Firebox management interfaces. The issue can interrupt firewall administration and degrade performance, but the provided evidence supports limited denial of service rather than compromise. Mitigation focus: Review WatchGuard security guidance and Fireware 11.12.2 release notes.; Upgrade affected Fireware deployments to a vendor-supported fixed release.; Restrict Firebox management and XML-RPC access to trusted administrative networks..
