How to fix?

Upgrade SLES:15.0 tomcat-el-3_0-api to version 9.0.36-3.84.1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream tomcat-el-3_0-api package and not the tomcat-el-3_0-api package as distributed by SLES. See How to fix? for SLES:15.0 relevant fixed versions and status.

Apache Tomcat 10.0.0-M1 to 10.0.6, 9.0.0.M1 to 9.0.46 and 8.5.0 to 8.5.66 did 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 ignored the transfer encoding header if the client declared it would only accept an HTTP/1.0 response; - Tomcat honoured the identify encoding; and - Tomcat did not ensure that, if present, the chunked encoding was the final encoding.
