CVE-2019-17569

MEDIUM

Apache Tomcat 7.0.98-7.0.99, 8.5.48-8.5.50, 9.0.28-9.0.30 - HTTP Request Smuggling via Invalid Transfer-Encoding Header

Title source: llm

Description

The refactoring present in Apache Tomcat 9.0.28 to 9.0.30, 8.5.48 to 8.5.50 and 7.0.98 to 7.0.99 introduced a regression. The result of the regression was that invalid Transfer-Encoding headers were incorrectly processed leading to a possibility of HTTP Request Smuggling if Tomcat was located behind a reverse proxy that incorrectly handled the invalid Transfer-Encoding header in a particular manner. Such a reverse proxy is considered unlikely.
