HIGH7.5EPSS 2.2%Undertow MadeYouReset HTTP/2 DDoS Vulnerability
發布日:2025/9/2修改日:2026/4/28
描述
A flaw was found in Undertow where malformed client requests can trigger server-side stream resets without triggering abuse counters. This issue, referred to as the "MadeYouReset" attack, allows malicious clients to induce excessive server workload by repeatedly causing server-side stream aborts. While not a protocol bug, this highlights a common implementation weakness that can be exploited to cause a denial of service (DoS).
