Synopsis

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

Description

The version of tomcat7 installed on the remote host is prior to 7.0.109-1.41. It is, therefore, affected by a vulnerability as referenced in the ALAS-2021-1534 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)

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

Solution

Run 'yum update tomcat7' to update your system.
