Vulnerability Details

CVEID: CVE-2021-44228
DESCRIPTION: Apache Log4j could allow a remote attacker to execute arbitrary code on the system, caused by the failure to protect against attacker controlled LDAP and other JNDI related endpoints by JNDI features. By sending a specially crafted code string, an attacker could exploit this vulnerability to load arbitrary Java code on the server and take complete control of the system. Note: The vulnerability is also called Log4Shell or LogJam.
CVSS Base score: 10
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/214921 for the current score.

CVEID: CVE-2021-45046
DESCRIPTION: Apache Log4j could allow a remote attacker to execute arbitrary code on the system, caused by an incomplete fix of CVE-2021-44228 in certain non-default configurations. A remote attacker with control over Thread Context Map (MDC) input data can craft malicious input data using a JNDI Lookup pattern to obtain sensitive information and execute arbitrary code on the system.
