Summary

Apache Log4j Java logging library vulnerability - CVE-2021-45046 (affecting versions prior to v2.16) impacts DCNM Network Management Software.

Vulnerability Details

CVEID:CVE-2021-45046
**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.
CVSS Base score: 9
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/215195 for the current score.
