Title

Apache NiFi拒绝服务漏洞（CNVD-2018-26519）

Description

Apache NiFi是美国阿帕奇（Apache）软件基金会的一套基于数据流的数据处理和分发系统。该系统支持数据路由指示图的配置和转换以及系统中介逻辑等。 Apache NiFi 1.0.0版本至1.7.1版本中存在安全漏洞，该漏洞源于对于删除请求，程序会忽略请求主体，但当初始请求带有非零的Content-Length值时，接收的节点会一直等待请求主体直至超时。攻击者可利用该漏洞造成拒绝服务。

CVE-2018-17194 (GCVE-0-2018-17194)

Vulnerability from cvelistv5 – Published: 2018-12-19 14:00 – Updated: 2024-08-05 10:39

Summary

When a client request to a cluster node was replicated to other nodes in the cluster for verification, the Content-Length was forwarded. On a DELETE request, the body was ignored, but if the initial request had a Content-Length value other than 0, the receiving nodes would wait for the body and eventually timeout. Mitigation: The fix to check DELETE requests and overwrite non-zero Content-Length header values was applied on the Apache NiFi 1.8.0 release. Users running a prior 1.x release should upgrade to the appropriate release.
