低危 Transfer-Encoding标头的处理不当会导致HTTP请求走私
CVE编号
CVE-2020-1935利用情况
暂无补丁情况
官方补丁披露时间
2020-02-25漏洞描述
在Apache Tomcat 9.0.0.M1到9.0.30、8.5.0到8.5.50和7.0.0到7.0.99中，HTTP标头解析代码使用了行末解析的方法，该方法允许一些无效的HTTP标头被解析为有效。如果Tomcat位于反向代理后面，而反向代理以特定方式错误地处理了无效的Transfer-Encoding标头，则可能导致HTTP请求走私。这种反向代理被认为是不可能的。解决建议
建议您更新当前系统或软件至最新版，完成漏洞的修复。受影响软件情况
