Multiple vulnerabilities in Apache Log4j affect the IBM WebSphere Application Server and IBM Security Guardium Key Lifecycle Manager (CVE-2021-4104, CVE-2021-45046, CVE-2021-45105 and CVE-2021-44832). The fix addresses the vulnerability by removing Apache Log4j.
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
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/215048 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.
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:C/C:H/I:H/A:H)
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:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H)
CVEID:CVE-2021-44832
**DESCRIPTION:**Apache Log4j could allow a remote attacker with permission to modify the logging configuration file to execute arbitrary code on the system. By constructing a malicious configuration using a JDBC Appender with a data source referencing a JNDI URI , an attacker could exploit this vulnerability to execute remote code.
CVSS Base score: 6.6
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/216189 for the current score.
