Amazon Linux AMI : tomcat8 (ALAS-2023-1732)

medium Nessus Plugin ID 174622

Synopsis

The remote Amazon Linux AMI host is missing a security update.

Description

The version of tomcat8 installed on the remote host is prior to 8.5.87-1.92. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS-2023-1732 advisory.

- The simplified implementation of blocking reads and writes introduced in Tomcat 10 and back-ported to Tomcat 9.0.47 onwards exposed a long standing (but extremely hard to trigger) concurrency bug in Apache Tomcat 10.1.0 to 10.1.0-M12, 10.0.0-M1 to 10.0.18, 9.0.0-M1 to 9.0.60 and 8.5.0 to 8.5.77 that could cause client connections to share an Http11Processor instance resulting in responses, or part responses, to be received by the wrong client. (CVE-2021-43980)

- When using the RemoteIpFilter with requests received from a reverse proxy via HTTP that include the X-Forwarded-Proto header set to https, session cookies created by Apache Tomcat 11.0.0-M1 to 11.0.0.-M2, 10.1.0-M1 to 10.1.5, 9.0.0-M1 to 9.0.71 and 8.5.0 to 8.5.85 did not include the secure attribute. This could result in the user agent transmitting the session cookie over an insecure channel. (CVE-2023-28708)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Run 'yum update tomcat8' to update your system.
