Amazon Linux 2 : aws-kinesis-agent (ALAS-2021-1730)

critical Nessus Plugin ID 156112

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 2.0.4-1. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2021-1730 advisory.

- Apache Log4j2 2.0-beta9 through 2.12.1 and 2.13.0 through 2.15.0 JNDI features used in configuration, log messages, and parameters do not protect against attacker controlled LDAP and other JNDI related endpoints.
An attacker who can control log messages or log message parameters can execute arbitrary code loaded from LDAP servers when message lookup substitution is enabled. From log4j 2.15.0, this behavior has been disabled by default. From version 2.16.0, this functionality has been completely removed. Note that this vulnerability is specific to log4j-core and does not affect log4net, log4cxx, or other Apache Logging Services projects. (CVE-2021-44228)

- It was found that the fix to address CVE-2021-44228 in Apache Log4j 2.15.0 was incomplete in certain non- default configurations. This could allows attackers with control over Thread Context Map (MDC) input data when the logging configuration uses a non-default Pattern Layout with either a Context Lookup (for example, $${ctx:loginId}) or a Thread Context Map pattern (%X, %mdc, or %MDC) to craft malicious input data using a JNDI Lookup pattern resulting in a denial of service (DOS) attack. Log4j 2.15.0 makes a best- effort attempt to restrict JNDI LDAP lookups to localhost by default. Log4j 2.16.0 fixes this issue by removing support for message lookup patterns and disabling JNDI functionality by default. (CVE-2021-45046)

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.
