CVE-2020-9493 identified a deserialization issue that was present in Apache Chainsaw. Prior to Chainsaw V2.0 Chainsaw was a component of Apache Log4j 1.2.x where the same issue exists. CVE-2020-9493 identificó un problema de deserialización presente en Apache Chainsaw. Versiones anteriores a Chainsaw V2.0 Chainsaw era un componente de Apache Log4j versiones 1.2.x donde se presenta el mismo problema A flaw was found in the log4j 1.x chainsaw component, where the contents of certain log entries are deserialized and possibly permit code execution. This flaw allows an attacker to send a malicious request with serialized data to the server to be deserialized when the chainsaw component is run. • https://lists.apache.org/thread/rg4yyc89vs3dw6kpy3r92xop9loywyhh https://logging.apache.org/log4j/1.2/index.html https://www.oracle.com/security-alerts/cpuapr2022.html https://www.oracle.com/security-alerts/cpujul2022.html https://access.redhat.com/security/cve/CVE-2022-23307 https://bugzilla.redhat.com/show_bug.cgi?id=2041967 • CWE-502: Deserialization of Untrusted Data •
CVSS: 9.8EPSS: 0%CPEs: 42EXPL: 0CVE-2022-23305 – SQL injection in JDBC Appender in Apache Log4j V1
https://notcve.org/view.php?id=CVE-2022-23305
By design, the JDBCAppender in Log4j 1.2.x accepts an SQL statement as a configuration parameter where the values to be inserted are converters from PatternLayout. The message converter, %m, is likely to always be included. This allows attackers to manipulate the SQL by entering crafted strings into input fields or headers of an application that are logged allowing unintended SQL queries to be executed. Note this issue only affects Log4j 1.x when specifically configured to use the JDBCAppender, which is not the default. Beginning in version 2.0-beta8, the JDBCAppender was re-introduced with proper support for parameterized SQL queries and further customization over the columns written to in logs. • http://www.openwall.com/lists/oss-security/2022/01/18/4 https://lists.apache.org/thread/pt6lh3pbsvxqlwlp4c5l798dv2hkc85y https://logging.apache.org/log4j/1.2/index.html https://security.netapp.com/advisory/ntap-20220217-0007 https://www.oracle.com/security-alerts/cpuapr2022.html https://www.oracle.com/security-alerts/cpujul2022.html https://access.redhat.com/security/cve/CVE-2022-23305 https://bugzilla.redhat.com/show_bug.cgi?id=2041959 • CWE-89: Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') •
CVSS: 8.8EPSS: 0%CPEs: 40EXPL: 0CVE-2022-23302 – Deserialization of untrusted data in JMSSink in Apache Log4j 1.x
https://notcve.org/view.php?id=CVE-2022-23302
JMSSink in all versions of Log4j 1.x is vulnerable to deserialization of untrusted data when the attacker has write access to the Log4j configuration or if the configuration references an LDAP service the attacker has access to. The attacker can provide a TopicConnectionFactoryBindingName configuration causing JMSSink to perform JNDI requests that result in remote code execution in a similar fashion to CVE-2021-4104. Note this issue only affects Log4j 1.x when specifically configured to use JMSSink, 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. • http://www.openwall.com/lists/oss-security/2022/01/18/3 https://lists.apache.org/thread/bsr3l5qz4g0myrjhy9h67bcxodpkwj4w https://logging.apache.org/log4j/1.2/index.html https://security.netapp.com/advisory/ntap-20220217-0006 https://www.oracle.com/security-alerts/cpuapr2022.html https://www.oracle.com/security-alerts/cpujul2022.html https://access.redhat.com/security/cve/CVE-2022-23302 https://bugzilla.redhat.com/show_bug.cgi?id=2041949 • CWE-502: Deserialization of Untrusted Data •

https://notcve.org/view.php?id=CVE-2020-9488
Improper validation of certificate with host mismatch in Apache Log4j SMTP appender. This could allow an SMTPS connection to be intercepted by a man-in-the-middle attack which could leak any log messages sent through that appender. Fixed in Apache Log4j 2.12.3 and 2.13.1 Validación incorrecta del certificado con desajuste de host en el apéndice SMTP de Apache Log4j. Esto podría permitir que una conexión SMTPS fuera interceptada por un ataque de tipo man-in-the-middle que podría filtrar cualquier mensaje de registro enviado a través de ese appender. Corregido en Apache Log4j 2.12.3 y 2.13.1 • https://issues.apache.org/jira/browse/LOG4J2-2819 https://lists.apache.org/thread.html/r0a2699f724156a558afd1abb6c044fb9132caa66dce861b82699722a%40%3Cjira.kafka.apache.org%3E https://lists.apache.org/thread.html/r0df3d7a5acb98c57e64ab9266aa21eeee1d9b399addb96f9cf1cbe05%40%3Cdev.zookeeper.apache.org%3E https://lists.apache.org/thread.html/r1fc73f0e16ec2fa249d3ad39a5194afb9cc5afb4c023dc0bab5a5881%40%3Cissues.hive.apache.org%3E https://lists.apache.org/thread.html/r22a56beb76dd8cf18e24fda9072f1e05990f49d6439662d3782a392f%40%3Cissues.hive.apache.org%3E https://lists.apache.o • CWE-295: Improper Certificate Validation •
