Amazon Linux AMI : tomcat8 (ALAS-2023-1779)

high Nessus Plugin ID 178510

Language:

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 8.5.89-1.93. It is, therefore, affected by a vulnerability as referenced in the ALAS-2023-1779 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)

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 tomcat8' to update your system.
