Cisco Identity Services Log4j Engine Remote Code Execution (cisco-sa-apache-log4j-qRuKNEbd)

critical Nessus Plugin ID 160400

Synopsis

A package installed on the remote host is affected by a remote code execution vulnerability.

Description

Cisco Identity Services Engine is affected by the following critical vulnerability in the Apache Log4j Java logging library as descibed in the cisco-sa-apache-log4j-qRuKNEbd 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)

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