Vulnerability Title
Undertow: ajp request closes connection exceeding maxrequestsize
来源: 美国国家漏洞数据库 NVD
Vulnerability Description
A flaw was found in Undertow. When an AJP request is sent that exceeds the max-header-size attribute in ajp-listener, JBoss EAP is marked in an error state by mod_cluster in httpd, causing JBoss EAP to close the TCP connection without returning an AJP response. This happens because mod_proxy_cluster marks the JBoss EAP instance as an error worker when the TCP connection is closed from the backend after sending the AJP request without receiving an AJP response, and stops forwarding. This issue could allow a malicious user could to repeatedly send requests that exceed the max-header-size, causing a Denial of Service (DoS).

Red Hat Undertow 安全漏洞
来源: 中国国家信息安全漏洞库 CNNVD
Vulnerability Description
Red Hat Undertow是美国红帽（Red Hat）公司的一款基于Java的嵌入式Web服务器，是Wildfly（Java应用服务器）默认的Web服务器。 Red Hat Undertow 存在安全漏洞，该漏洞源于当发送 AJP 请求后未收到 AJP 响应，从后端关闭 TCP 连接时，mod_proxy_cluster 会将 JBoss EAP 实例标记为错误工作器并停止转发，攻击者利用该漏洞可以重复发送超过最大标头大小的请求，从而导致拒绝服务。
