Amazon Linux 2 Security Advisory: ALASTOMCAT9-2023-007
Advisory Release Date: 2023-08-21 20:58 Pacific
Advisory Updated Date: 2023-09-25 21:57 Pacific
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. (CVE-2021-33037)
