"value": "JMSAppender in Log4j 1.2 is vulnerable to deserialization of untrusted data when the attacker has write access to the Log4j configuration. The attacker can provide TopicBindingName and TopicConnectionFactoryBindingName configurations causing JMSAppender to perform JNDI requests that result in remote code execution in a similar fashion to CVE-2021-44228. Note this issue only affects Log4j 1.2 when specifically configured to use JMSAppender, which is not the default. Apache Log4j 1.2 reached end of life in August 2015. Users should upgrade to Log4j 2 as it addresses numerous other issues from the previous versions."

Note this issue only affects Log4j 1.2 when specifically configured to use JMSAppender, which is not the default. Apache Log4j 1.2 reached end of life in August 2015.

The attacker can provide TopicBindingName and TopicConnectionFactoryBindingName configurations causing JMSAppender to perform JNDI requests that result in remote code execution in a similar fashion to CVE-2021-44228. Note this issue only affects Log4j 1.2 when specifically configured to use JMSAppender, which is not the default. Apache Log4j 1.2 reached end of life in August 2015. Users should upgrade to Log4j 2 as it addresses numerous other issues from the previous versions.",

This flaw has been filed for Log4j 1.x, and the corresponding flaw information for Log4j 2.x is available at: https://access.redhat.com/security/cve/CVE-2021-44228\n\nNote this flaw ONLY affects applications which are specifically configured to use JMSAppender, which is not the default, or when the attacker has write access to the Log4j configuration for adding JMSAppender to the attacker\u0027s JNDI LDAP endpoint. \n\nIf the Log4j configuration is set TopicBindingName or TopicConnectionFactoryBindingName configurations allowing JMSAppender to perform JNDI requests that result in remote code execution in a similar fashion to CVE-2021-44228 Log4j 2.x, Log4j 1.x is vulnerable. However, the attack vector is reduced as it depends on having write access, which is not a standard configuration rather than untrusted user input. These are sufficient factors beyond the attacker\u0027s control.\n\nThe tomcat package shipped with Red Hat Enterprise Linux does not include log4j but it does include a default configuration for log4j, log4j.properties, which could be used with tomcat if users choose to install and configure the library. The JMSAppender is not enabled by default, and the permissions of the file can only be modified as root.\n\nRed Hat Virtualization ships log4j12-1.2.17, but it is used and configured in a way which makes this flaw not possible to exploit. Therefore impact is rated Low.",

"text": "Although we have matched Apache\u0027s CVSS score, with the exception of the scope metric which will remain unaltered at \"unchanged\"; as we believe code execution would be at the permission levels of the running JVM and not exceeding that of the original CVE-2021-44228 flaw.\n \nWe have given this vulnerability an impact rating of Moderate, this is because of the unlikely nature of log4j lookup mapping values being derived from attacker controlled values. This is not the default configuration for end-applications using log4j 2.x and would require explicit action from a privileged user (a developer or administrator) to access the vulnerability. \nIn certain non-default configurations, it was found that the fix to address CVE-2021-44228 in Apache Log4j 2.15.0 was insufficient.\n\nThis issue affects the log4j version between 2.0 and 2.15. Log4j 1.x is NOT impacted by this vulnerability. \n\nPrerequisites to exploit this flaw are :\n\n- A remotely accessible endpoint with any protocol (HTTP, TCP, etc) that allows an attacker to send arbitrary data,\n- A log statement in the endpoint that logs the attacker controlled data.\n- Log4j configuration file should be explicitly configured to use a non-default Pattern Layout with a Context Lookup eg. ($${ctx:loginId}) \n\nIn most cases, the mitigation suggested for CVE-2021-44228 (i.e. to set the system property `log4j2.noFormatMsgLookup` to `true) does NOT mitigate this specific vulnerability. \nLog4j 2.16.0 fixes this issue by removing support for message lookup patterns and disabling JNDI functionality by default.\n\nFor Elasticsearch, as shipped in OpenShift 3.11, the \"log4j2.formatMsgNoLookups=true\" system property mitigation is sufficient as there are no included non-standard configurations that allow for exploitation:\n\nhttps://github.com/openshift/openshift-ansible/blob/release-3.11/roles/openshift_logging_elasticsearch/templates/log4j2.properties.j2\n\nhttps://discuss.elastic.co/t/apache-log4j2-remote-code-execution-rce-vulnerability-cve-2021-44228-esa-2021-31/291476\n\nFor CodeReady Studio the fix for this flaw is available on CodeReady Studio 12.21.3 and above versions.",

Vulnerability from csaf_redhat - Published: 2021-12-16 07:50 - Updated: 2026-05-28 21:10A flaw was found in the Java logging library Apache Log4j in version 1.x. JMSAppender in Log4j 1.x is vulnerable to deserialization of untrusted data. This allows a remote attacker to execute code on the server if the deployed application is configured to use JMSAppender and to the attacker's JNDI LDAP endpoint.

"text": "Based on the conditions to be exploitable (see details below), the risk is much lower than Log4j 2.x and Red Hat has assessed this to be Moderate severity. This flaw has been filed for Log4j 1.x, and the corresponding flaw information for Log4j 2.x is available at: https://access.redhat.com/security/cve/CVE-2021-44228\n\nNote this flaw ONLY affects applications which are specifically configured to use JMSAppender, which is not the default, or when the attacker has write access to the Log4j configuration for adding JMSAppender to the attacker\u0027s JNDI LDAP endpoint. \n\nIf the Log4j configuration is set TopicBindingName or TopicConnectionFactoryBindingName configurations allowing JMSAppender to perform JNDI requests that result in remote code execution in a similar fashion to CVE-2021-44228 Log4j 2.x, Log4j 1.x is vulnerable. However, the attack vector is reduced as it depends on having write access, which is not a standard configuration rather than untrusted user input. These are sufficient factors beyond the attacker\u0027s control.\n\nThe tomcat package shipped with Red Hat Enterprise Linux does not include log4j but it does include a default configuration for log4j, log4j.properties, which could be used with tomcat if users choose to install and configure the library. The JMSAppender is not enabled by default, and the permissions of the file can only be modified as root.\n\nRed Hat Virtualization ships log4j12-1.2.17, but it is used and configured in a way which makes this flaw not possible to exploit. Therefore impact is rated Low.",

In order to exploit this flaw you need:\n- A remotely accessible endpoint with any protocol (HTTP, TCP, etc) that allows an attacker to send arbitrary data,\n- A log statement in the endpoint that logs the attacker controlled data.\n\nIn Red Hat OpenShift Logging the vulnerable log4j library is shipped in the Elasticsearch components. Because Elasticsearch is not susceptible to remote code execution with this vulnerability due to use of the Java Security Manager and because access to these components is limited, the impact by this vulnerability is reduced to Moderate.\n\nAs per upstream applications using Log4j 1.x may be impacted by this flaw if their configuration uses JNDI. However, the risk is much lower. This flaw in Log4j 1.x is tracked via https://access.redhat.com/security/cve/CVE-2021-4104 and has been rated as having Moderate security impact.\n\nCodeReady Studio version 12.21.1 was released containing a fix for this vulnerability.\n\nThe following products are NOT affected by this flaw and have been explicitly listed here for the benefit of our customers.\n- Red Hat Enterprise Linux\n- Red Hat Advanced Cluster Management for Kubernetes \n- Red Hat Advanced Cluster Security for Kubernetes\n- Red Hat Ansible Automation Platform (Engine and Tower)\n- Red Hat Certificate System\n- Red Hat Directory Server\n- Red Hat Identity Management\n- Red Hat CloudForms \n- Red Hat Update Infrastructure\n- Red Hat Satellite\n- Red Hat Ceph Storage\n- Red Hat Gluster Storage\n- Red Hat OpenShift Data Foundation\n- Red Hat OpenStack Platform\n- Red Hat Virtualization\n- Red Hat Single Sign-On\n- Red Hat 3scale API Management",

This is not the default configuration for end-applications using log4j 2.x and would require explicit action from a privileged user (a developer or administrator) to access the vulnerability. \nIn certain non-default configurations, it was found that the fix to address CVE-2021-44228 in Apache Log4j 2.15.0 was insufficient.\n\nThis issue affects the log4j version between 2.0 and 2.15. Log4j 1.x is NOT impacted by this vulnerability. \n\nPrerequisites to exploit this flaw are :\n\n- A remotely accessible endpoint with any protocol (HTTP, TCP, etc) that allows an attacker to send arbitrary data,\n- A log statement in the endpoint that logs the attacker controlled data.\n- Log4j configuration file should be explicitly configured to use a non-default Pattern Layout with a Context Lookup eg. ($${ctx:loginId}) \n\nIn most cases, the mitigation suggested for CVE-2021-44228 (i.e. to set the system property `log4j2.noFormatMsgLookup` to `true) does NOT mitigate this specific vulnerability. \nLog4j 2.16.0 fixes this issue by removing support for message lookup patterns and disabling JNDI functionality by default.\n\nFor Elasticsearch, as shipped in OpenShift 3.11, the \"log4j2.formatMsgNoLookups=true\" system property mitigation is sufficient as there are no included non-standard configurations that allow for exploitation:\n\nhttps://github.com/openshift/openshift-ansible/blob/release-3.11/roles/openshift_logging_elasticsearch/templates/log4j2.properties.j2\n\nhttps://discuss.elastic.co/t/apache-log4j2-remote-code-execution-rce-vulnerability-cve-2021-44228-esa-2021-31/291476\n\nFor CodeReady Studio the fix for this flaw is available on CodeReady Studio 12.21.3 and above versions.",

RHSA-2021:5148
Vulnerability from csaf_redhat - Published: 2021-12-15 20:09 - Updated: 2026-05-28 21:10A flaw was found in the Java logging library Apache Log4j in version 1.x. JMSAppender in Log4j 1.x is vulnerable to deserialization of untrusted data. This allows a remote attacker to execute code on the server if the deployed application is configured to use JMSAppender and to the attacker's JNDI LDAP endpoint.

A flaw was found in the Apache Log4j logging library in versions from 2.0.0 and before 2.16.0. A remote attacker with control over Thread Context Map (MDC) input data could craft malicious input using a JNDI Lookup pattern resulting in remote code execution (RCE) in a limited number of environments.

This flaw has been filed for Log4j 1.x, and the corresponding flaw information for Log4j 2.x is available at: https://access.redhat.com/security/cve/CVE-2021-44228\n\nNote this flaw ONLY affects applications which are specifically configured to use JMSAppender, which is not the default, or when the attacker has write access to the Log4j configuration for adding JMSAppender to the attacker\u0027s JNDI LDAP endpoint. \n\nIf the Log4j configuration is set TopicBindingName or TopicConnectionFactoryBindingName configurations allowing JMSAppender to perform JNDI requests that result in remote code execution in a similar fashion to CVE-2021-44228 Log4j 2.x, Log4j 1.x is vulnerable. However, the attack vector is reduced as it depends on having write access, which is not a standard configuration rather than untrusted user input. These are sufficient factors beyond the attacker\u0027s control.\n\nThe tomcat package shipped with Red Hat Enterprise Linux does not include log4j but it does include a default configuration for log4j, log4j.properties, which could be used with tomcat if users choose to install and configure the library. The JMSAppender is not enabled by default, and the permissions of the file can only be modified as root.\n\nRed Hat Virtualization ships log4j12-1.2.17, but it is used and configured in a way which makes this flaw not possible to exploit. Therefore impact is rated Low.",

"text": "Although we have matched Apache\u0027s CVSS score, with the exception of the scope metric which will remain unaltered at \"unchanged\"; as we believe code execution would be at the permission levels of the running JVM and not exceeding that of the original CVE-2021-44228 flaw.\n \nWe have given this vulnerability an impact rating of Moderate, this is because of the unlikely nature of log4j lookup mapping values being derived from attacker controlled values. This is not the default configuration for end-applications using log4j 2.x and would require explicit action from a privileged user (a developer or administrator) to access the vulnerability. \nIn certain non-default configurations, it was found that the fix to address CVE-2021-44228 in Apache Log4j 2.15.0 was insufficient.\n\nThis issue affects the log4j version between 2.0 and 2.15. Log4j 1.x is NOT impacted by this vulnerability. \n\nPrerequisites to exploit this flaw are :\n\n- A remotely accessible endpoint with any protocol (HTTP, TCP, etc) that allows an attacker to send arbitrary data,\n- A log statement in the endpoint that logs the attacker controlled data.\n- Log4j configuration file should be explicitly configured to use a non-default Pattern Layout with a Context Lookup eg. ($${ctx:loginId}) \n\nIn most cases, the mitigation suggested for CVE-2021-44228 (i.e. to set the system property `log4j2.noFormatMsgLookup` to `true) does NOT mitigate this specific vulnerability. \nLog4j 2.16.0 fixes this issue by removing support for message lookup patterns and disabling JNDI functionality by default.\n\nFor Elasticsearch, as shipped in OpenShift 3.11, the \"log4j2.formatMsgNoLookups=true\" system property mitigation is sufficient as there are no included non-standard configurations that allow for exploitation:\n\nhttps://github.com/openshift/openshift-ansible/blob/release-3.11/roles/openshift_logging_elasticsearch/templates/log4j2.properties.j2\n\nhttps://discuss.elastic.co/t/apache-log4j2-remote-code-execution-rce-vulnerability-cve-2021-44228-esa-2021-31/291476\n\nFor CodeReady Studio the fix for this flaw is available on CodeReady Studio 12.21.3 and above versions.",

RHSA-2021:5183
Vulnerability from csaf_redhat - Published: 2021-12-16 21:14 - Updated: 2026-05-28 21:10A flaw was found in the Java logging library Apache Log4j in version 1.x. JMSAppender in Log4j 1.x is vulnerable to deserialization of untrusted data. This allows a remote attacker to execute code on the server if the deployed application is configured to use JMSAppender and to the attacker's JNDI LDAP endpoint.

It was found that the original fix for log4j CVE-2021-44228 and CVE-2021-45046 in the OpenShift metering hive containers was incomplete, as not all JndiLookup.class files were removed.

However, the attack vector is reduced as it depends on having write access, which is not a standard configuration rather than untrusted user input. These are sufficient factors beyond the attacker\u0027s control.\n\nThe tomcat package shipped with Red Hat Enterprise Linux does not include log4j but it does include a default configuration for log4j, log4j.properties, which could be used with tomcat if users choose to install and configure the library. The JMSAppender is not enabled by default, and the permissions of the file can only be modified as root.\n\nRed Hat Virtualization ships log4j12-1.2.17, but it is used and configured in a way which makes this flaw not possible to exploit. Therefore impact is rated Low.",

RHSA-2021:5184
Vulnerability from csaf_redhat - Published: 2021-12-16 21:40 - Updated: 2026-05-28 21:10A flaw was found in the Java logging library Apache Log4j in version 1.x. JMSAppender in Log4j 1.x is vulnerable to deserialization of untrusted data. This allows a remote attacker to execute code on the server if the deployed application is configured to use JMSAppender and to the attacker's JNDI LDAP endpoint.

"text": "Based on the conditions to be exploitable (see details below), the risk is much lower than Log4j 2.x and Red Hat has assessed this to be Moderate severity. This flaw has been filed for Log4j 1.x, and the corresponding flaw information for Log4j 2.x is available at: https://access.redhat.com/security/cve/CVE-2021-44228\n\nNote this flaw ONLY affects applications which are specifically configured to use JMSAppender, which is not the default, or when the attacker has write access to the Log4j configuration for adding JMSAppender to the attacker\u0027s JNDI LDAP endpoint. \n\nIf the Log4j configuration is set TopicBindingName or TopicConnectionFactoryBindingName configurations allowing JMSAppender to perform JNDI requests that result in remote code execution in a similar fashion to CVE-2021-44228 Log4j 2.x, Log4j 1.x is vulnerable. However, the attack vector is reduced as it depends on having write access, which is not a standard configuration rather than untrusted user input. These are sufficient factors beyond the attacker\u0027s control.\n\nThe tomcat package shipped with Red Hat Enterprise Linux does not include log4j but it does include a default configuration for log4j, log4j.properties, which could be used with tomcat if users choose to install and configure the library. The JMSAppender is not enabled by default, and the permissions of the file can only be modified as root.\n\nRed Hat Virtualization ships log4j12-1.2.17, but it is used and configured in a way which makes this flaw not possible to exploit. Therefore impact is rated Low.",

Vulnerability from csaf_redhat - Published: 2021-12-16 22:34 - Updated: 2026-05-28 21:10A flaw was found in the Java logging library Apache Log4j in version 1.x. JMSAppender in Log4j 1.x is vulnerable to deserialization of untrusted data. This allows a remote attacker to execute code on the server if the deployed application is configured to use JMSAppender and to the attacker's JNDI LDAP endpoint.

It was found that the original fix for log4j CVE-2021-44228 and CVE-2021-45046 in the OpenShift metering hive containers was incomplete, as not all JndiLookup.class files were removed.

This flaw has been filed for Log4j 1.x, and the corresponding flaw information for Log4j 2.x is available at: https://access.redhat.com/security/cve/CVE-2021-44228\n\nNote this flaw ONLY affects applications which are specifically configured to use JMSAppender, which is not the default, or when the attacker has write access to the Log4j configuration for adding JMSAppender to the attacker\u0027s JNDI LDAP endpoint. \n\nIf the Log4j configuration is set TopicBindingName or TopicConnectionFactoryBindingName configurations allowing JMSAppender to perform JNDI requests that result in remote code execution in a similar fashion to CVE-2021-44228 Log4j 2.x, Log4j 1.x is vulnerable. However, the attack vector is reduced as it depends on having write access, which is not a standard configuration rather than untrusted user input. These are sufficient factors beyond the attacker\u0027s control.\n\nThe tomcat package shipped with Red Hat Enterprise Linux does not include log4j but it does include a default configuration for log4j, log4j.properties, which could be used with tomcat if users choose to install and configure the library. The JMSAppender is not enabled by default, and the permissions of the file can only be modified as root.\n\nRed Hat Virtualization ships log4j12-1.2.17, but it is used and configured in a way which makes this flaw not possible to exploit. Therefore impact is rated Low.",

RHSA-2021:5206
Vulnerability from csaf_redhat - Published: 2021-12-20 09:54 - Updated: 2026-05-28 21:10A flaw was found in the Java logging library Apache Log4j in version 1.x. JMSAppender in Log4j 1.x is vulnerable to deserialization of untrusted data. This allows a remote attacker to execute code on the server if the deployed application is configured to use JMSAppender and to the attacker's JNDI LDAP endpoint.

This allows a remote attacker to execute code on the server if the deployed application is configured to use JMSAppender and to the attacker\u0027s JNDI LDAP endpoint.",

"text": "Based on the conditions to be exploitable (see details below), the risk is much lower than Log4j 2.x and Red Hat has assessed this to be Moderate severity. This flaw has been filed for Log4j 1.x, and the corresponding flaw information for Log4j 2.x is available at: https://access.redhat.com/security/cve/CVE-2021-44228\n\nNote this flaw ONLY affects applications which are specifically configured to use JMSAppender, which is not the default, or when the attacker has write access to the Log4j configuration for adding JMSAppender to the attacker\u0027s JNDI LDAP endpoint. \n\nIf the Log4j configuration is set TopicBindingName or TopicConnectionFactoryBindingName configurations allowing JMSAppender to perform JNDI requests that result in remote code execution in a similar fashion to CVE-2021-44228 Log4j 2.x, Log4j 1.x is vulnerable. However, the attack vector is reduced as it depends on having write access, which is not a standard configuration rather than untrusted user input. These are sufficient factors beyond the attacker\u0027s control.\n\nThe tomcat package shipped with Red Hat Enterprise Linux does not include log4j but it does include a default configuration for log4j, log4j.properties, which could be used with tomcat if users choose to install and configure the library. The JMSAppender is not enabled by default, and the permissions of the file can only be modified as root.\n\nRed Hat Virtualization ships log4j12-1.2.17, but it is used and configured in a way which makes this flaw not possible to exploit. Therefore impact is rated Low.",

For example:\n```\nzip -q -d log4j-*.jar org/apache/log4j/net/JMSAppender.class\n```\n- Restrict access for the OS user on the platform running the application to prevent modifying the Log4j configuration by the attacker.",

"text": "Based on the conditions to be exploitable (see details below), the risk is much lower than Log4j 2.x and Red Hat has assessed this to be Moderate severity. This flaw has been filed for Log4j 1.x, and the corresponding flaw information for Log4j 2.x is available at: https://access.redhat.com/security/cve/CVE-2021-44228\n\nNote this flaw ONLY affects applications which are specifically configured to use JMSAppender, which is not the default, or when the attacker has write access to the Log4j configuration for adding JMSAppender to the attacker\u0027s JNDI LDAP endpoint. \n\nIf the Log4j configuration is set TopicBindingName or TopicConnectionFactoryBindingName configurations allowing JMSAppender to perform JNDI requests that result in remote code execution in a similar fashion to CVE-2021-44228 Log4j 2.x, Log4j 1.x is vulnerable. However, the attack vector is reduced as it depends on having write access, which is not a standard configuration rather than untrusted user input. These are sufficient factors beyond the attacker\u0027s control.\n\nThe tomcat package shipped with Red Hat Enterprise Linux does not include log4j but it does include a default configuration for log4j, log4j.properties, which could be used with tomcat if users choose to install and configure the library. The JMSAppender is not enabled by default, and the permissions of the file can only be modified as root.\n\nRed Hat Virtualization ships log4j12-1.2.17, but it is used and configured in a way which makes this flaw not possible to exploit. Therefore impact is rated Low.",
