Security readout for executives and security teams
CVE-2019-4279 is a critical remote code execution issue in IBM WebSphere Application Server 8.5 and 9.0. An unauthenticated remote attacker could execute arbitrary code using a specially crafted sequence of serialized objects from untrusted sources. Treat exposed WebSphere systems as high-priority assets. Organizations running IBM WebSphere Application Server 8.5 or 9.0 are potentially exposed, especially where WebSphere services are reachable from untrusted networks or process serialized input from external users or integrated systems. Prioritize remediation for internet-facing or business-critical WebSphere systems. Even without confirmed exploitation in the supplied sources, unauthenticated remote code execution on application servers can create material operational and data risk. Mitigation focus: Check IBM advisory for CVE-2019-4279 and apply vendor-recommended fixes for affected 8.5 or 9.0 deployments.; Restrict network access to exposed WebSphere services until remediation is confirmed.; Inventory all WebSphere Application Server 8.5 and 9.0 instances..
