Security readout for executives and security teams
CVE-2025-48989 is a high-severity denial-of-service issue in Apache Tomcat’s HTTP/2 handling. A remote, unauthenticated attacker could cause availability impact using the “Made You Reset” attack pattern. The main business risk is service disruption for applications running affected Tomcat versions with HTTP/2 exposure. Internet-facing Tomcat services are the primary concern, especially where HTTP/2 is enabled or reachable through front-end infrastructure. Internal Tomcat deployments can also be exposed if untrusted clients can reach them. Older end-of-life Tomcat versions may also be affected, but the sources do not provide complete version detail for them. Prioritize remediation for internet-facing or business-critical Tomcat applications. This is not described as code execution or data compromise, but downtime risk is high. Treat upgrades as a near-term availability protection task, especially for customer-facing services. Mitigation focus: Upgrade Tomcat 11 deployments to 11.0.10 or later.; Upgrade Tomcat 10.1 deployments to 10.1.44 or later.; Upgrade Tomcat 9 deployments to 9.0.108 or later..
