Title:	Apache Tomcat HTTP Request Smuggling Vulnerability (Jul 2021) - Windows
Summary:	Apache Tomcat is prone to an HTTP request smuggling vulnerability.
Description:	Summary: Apache Tomcat is prone to an HTTP request smuggling vulnerability. Vulnerability Insight: Apache Tomcat does not correctly parse the HTTP transfer-encoding request header in some circumstances leading to the possibility to request smuggling when used with a reverse proxy. Specifically: Tomcat incorrectly ignores the transfer-encoding header if the client declared it would only accept an HTTP/1.0 response. Tomcat honours the identify encoding and Tomcat does not ensure that, if present, the chunked encoding is the final encoding. Affected Software/OS: Apache Tomcat 8.5.x through 8.5.66, 9.0.0.M1 through 9.0.46 and 10.0.0-M1 through 10.0.6. Solution: Update to version 8.5.68, 9.0.48, 10.0.7 or later. CVSS Score: 5.0 CVSS Vector: AV:N/AC:L/Au:N/C:N/I:P/A:N
