medium Nessus Plugin ID 156263

Language:

Synopsis

The remote Amazon Linux 2 host is missing a security update.

Description

The version of aws-kinesis-agent installed on the remote host is prior to 2.0.5-1. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2021-1733 advisory.

 A flaw was found in the Apache Log4j logging library 2.x. when the logging configuration uses a non- default Pattern Layout with a Context Lookup. Attackers with control over Thread Context Map (MDC) input data can craft malicious input data that contains a recursive lookup and can cause Denial of Service.
 (CVE-2021-45105)

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 aws-kinesis-agent' to update your system.
