Synopsis
The remote Amazon Linux 2 host is missing a security update.Description
The version of tomcat installed on the remote host is prior to 8.5.69-1. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2TOMCAT8.5-2024-017 advisory.2024-02-15: CVE-2021-30640 was added to this advisory.
2024-02-15: CVE-2021-33037 was added to this advisory.
A vulnerability in the JNDI Realm of Apache Tomcat allows an attacker to authenticate using variations of a valid user name and/or to bypass some of the protection provided by the LockOut Realm. This issue affects Apache Tomcat 10.0.0-M1 to 10.0.5; 9.0.0.M1 to 9.0.45; 8.5.0 to 8.5.65. (CVE-2021-30640)
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.
