Summary

Apache Log4j is used by IBM Spectrum LSF Suite and IBM Platform Process Manager as part of its logging infrastructure. These vulnerabilities can be addressed by executing steps detailed in the Workaround section. These issues will be addressed in the next fix patch release 10.2.0.13 by end of July 2022.

Vulnerability Details

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.
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H)

CVEID:CVE-2020-9488
**DESCRIPTION:**Apache Log4j is vulnerable to a man-in-the-middle attack, caused by improper certificate validation with host mismatch in the SMTP appender. An attacker could exploit this vulnerability to launch a man-in-the-middle attack and gain access to the communication channel between endpoints to obtain sensitive information or further compromise the system.
CVSS Base score: 3.7
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/180824 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:N)

CVEID:CVE-2022-23302
**DESCRIPTION:**Apache Log4j could allow a remote authenticated attacker to execute arbitrary code on the system, caused by an unsafe deserialization in JMSSink. By sending specially-crafted JNDI requests using TopicConnectionFactoryBindingName configuration, an attacker could exploit this vulnerability to execute arbitrary code on the system.
CVSS Base score: 8.8
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/217460 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H)

CVEID:CVE-2022-23307
**DESCRIPTION:**Apache Log4j could allow a remote attacker to execute arbitrary code on the system, caused by an unsafe deserialization in the in Apache Chainsaw component. By sending specially-crafted input, an attacker could exploit this vulnerability to execute arbitrary code on the system.
CVSS Base score: 9.8
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/217462 for the current score.

CVEID:CVE-2019-17571
**DESCRIPTION:**Apache Log4j could allow a remote attacker to execute arbitrary code on the system, caused by improper deserialization of untrusted data in SocketServer. By sending a specially-crafted request, an attacker could exploit this vulnerability to execute arbitrary code on the system.
CVSS Base score: 9.8

CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H)

CVEID:CVE-2020-9493
**DESCRIPTION:**Apache Chainsaw could allow a remote attacker to execute arbitrary code on the system, caused by an unsafe deserialization flaw when reading the log events. By sending specially-crafted request, an attacker could exploit this vulnerability to execute arbitrary code on the system.
CVSS Base score: 9.8
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/203829 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H)

CVEID:CVE-2022-23305
**DESCRIPTION:**Apache Log4j is vulnerable to SQL injection. A remote attacker could send specially-crafted SQL statements to the JDBCAppender, which could allow the attacker to view, add, modify or delete information in the back-end database.
CVSS Base score: 6.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/217461 for the current score.

Executing these steps will remove the vulnerbilities in log4j:

Remove the JMSAppender.class, SMTPAppender.class, SMTPAppender$1.class, JMSSink.class, SocketServer.class, SimpleSocketServer.class and JDBCAppender.class from log4j-*.jar file

1). find $JS_HOME -name “log4j-*.jar” -exec zip -q -d {} org/apache/log4j/net/JMSAppender.class ;

find $JS_HOME -name “log4j-*.jar” -exec zip -q -d {} org/apache/log4j/net/SMTPAppender.class ;

find $JS_HOME -name “log4j-*.jar” -exec zip -q -d {} org/apache/log4j/net/SMTPAppender$1.class ;

find $JS_HOME -name “log4j-*.jar” -exec zip -q -d {} org/apache/log4j/net/JMSSink.class ;

find $JS_HOME -name “log4j-*.jar” -exec zip -q -d {} org/apache/log4j/net/SocketServer.class ;

find $JS_HOME -name “log4j-*.jar” -exec zip -q -d {} org/apache/log4j/net/SimpleSocketServer.class ;

find $JS_HOME -name “log4j-*.jar” -exec zip -q -d {} org/apache/log4j/jdbc/JDBCAppender.class ;

2). reboot service

jadmin stop

jadmin start
