Within IBM Planning Analytics 2.0, only the IBM Planning Analytics Workspace component of IBM Planning Analytics is affected by security vulnerabilties. Apache Log4j is used by IBM Planning Analytics Workspace as part of its logging infrastructure. This bulletin addresses the exposure to the Apache Log4j CVE-2021-45046 and CVE-2021-45105 vulnerabilities . IBM Planning Analytics Workspace 2.0 has upgraded Apache Log4j to v2.17. Please note that this update also addresses CVE-2021-44228.
DESCRIPTION: Apache Log4j could result in remote code execution, caused by an incomplete fix of CVE-2021-44228 in certain non-default configurations. When the logging configuration uses a non-default Pattern Layout with a Context Lookup, an attacker with control over Thread Context Map (MDC) input data can craft malicious input data using a JNDI Lookup pattern to leak sensitive information and remote code execution in some environments and local code execution in all environments.
