Quick assessment

Affected
Apache Software Foundation Apache NiFi
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Apache NiFi是美国Apache基金会开源的一款支持数据流转与处理的消息队列中间件。 Apache NiFi 1.5.0版本至2.10.0版本存在资源管理错误漏洞，该漏洞源于框架在压缩有效载荷上而非解压后输出上强制执行可配置的最大请求大小，可能导致恶意客户端发送特制请求消耗大量内存。

Vulnerability Title
Apache NiFi: Uncontrolled Resource Consumption through Decompression of HTTP Requests
Source: CVE Program / CVE List V5
Vulnerability Description
Apache NiFi 1.5.0 through 2.10.0 support gzip-encoded HTTP requests for the application REST API using a Jersey encoding filter. The framework enforced a configurable maximum request size on the compressed payload rather than the decompressed output, allowing a malicious client to send crafted requests that could consume excessive amounts of memory. Upgrading to Apache NiFi 2.11.0 is the recommended mitigation, which relocates response compression to Jetty Server and disables decompression of gzip-encoded HTTP requests.
