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 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.

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.

CVEID: CVE-2021-45105
DESCRIPTION: Apache Log4j is vulnerable to a denial of service, caused by the failure to protect from uncontrolled
recursion from self-referential lookups. A remote attacker with control over Thread Context Map (MDC) input data could
craft malicious input data that contains a recursive lookup to cause a StackOverflowError
that will terminate the process. Note: The vulnerability is also called LOG4J2-3230.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/215647 for the current score.

CVSS Vector: CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H
CVEID: CVE-2021-4104
DESCRIPTION: Apache Log4j could allow a remote attacker to execute arbitrary code on the system, caused by the
deserialization of untrusted data when the attacker has write access to the Log4j configuration. If the deployed application is configured to
use JMSAppender, an attacker could exploit this vulnerability to execute arbitrary code on the system.
CVSS Base score: 8.1
