Amazon Linux 2 : tomcat (ALASTOMCAT9-2023-001)

high Nessus Plugin ID 181983

Language:

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 9.0.76-1. It is, therefore, affected by a vulnerability as referenced in the ALAS2TOMCAT9-2023-001 advisory.

The fix for CVE-2023-24998 was incomplete for Apache Tomcat 11.0.0-M2 to 11.0.0-M4, 10.1.5 to 10.1.7, 9.0.71 to 9.0.73 and 8.5.85 to 8.5.87. If non-default HTTP connector settings were used such that the maxParameterCount could be reached using query string parameters and a request was submitted that supplied exactly maxParameterCount parameters in the query string, the limit for uploaded request parts could be bypassed with the potential for a denial of service to occur. (CVE-2023-28709)

Tenable has extracted the preceding description block directly from the tested product security advisory.

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 tomcat' to update your system.
