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 •
CVSS: 8.5EPSS: 2%CPEs: 71EXPL: 1CVE-2021-44832 – Apache Log4j2 vulnerable to RCE via JDBC Appender when attacker controls configuration
https://notcve.org/view.php?id=CVE-2021-44832
Apache Log4j2 versions 2.0-beta7 through 2.17.0 (excluding security fix releases 2.3.2 and 2.12.4) are vulnerable to a remote code execution (RCE) attack when a configuration uses a JDBC Appender with a JNDI LDAP data source URI when an attacker has control of the target LDAP server. This issue is fixed by limiting JNDI data source names to the java protocol in Log4j2 versions 2.17.1, 2.12.4, and 2.3.2. Las versiones de Apache Log4j2 de la 2.0-beta7 a la 2.17.0 (excluyendo las versiones de corrección de seguridad 2.3.2 y 2.12.4) son vulnerables a un ataque de ejecución remota de código (RCE) cuando una configuración utiliza un JDBC Appender con un URI de origen de datos JNDI LDAP cuando un atacante tiene el control del servidor LDAP de destino. Este problema se soluciona limitando los nombres de fuentes de datos JNDI al protocolo java en las versiones 2.17.1, 2.12.4 y 2.3.2 de Log4j2 Apache Log4j2 versions 2.0-beta7 through 2.17.0 (excluding security fix releases 2.3.2 and 2.12.4) are vulnerable to a remote code execution (RCE) attack where an attacker with permission to modify the logging configuration file can construct a malicious configuration using a JDBC Appender with a data source referencing a JNDI URI which can execute remote code. This issue is fixed by limiting JNDI data source names to the java protocol in Log4j2 versions 2.17.1, 2.12.4, and 2.3.2. • https://github.com/thedevappsecguy/Log4J-Mitigation-CVE-2021-44228--CVE-2021-45046--CVE-2021-45105--CVE-2021-44832 http://www.openwall.com/lists/oss-security/2021/12/28/1 https://cert-portal.siemens.com/productcert/pdf/ssa-784507.pdf https://issues.apache.org/jira/browse/LOG4J2-3293 https://lists.apache.org/thread/s1o5vlo78ypqxnzn6p8zf6t9shtq5143 https://lists.debian.org/debian-lts-announce/2021/12/msg00036.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject • CWE-20: Improper Input Validation CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection') •
CVSS: 5.9EPSS: 96%CPEs: 213EXPL: 7CVE-2021-45105 – Apache Log4j2 does not always protect from infinite recursion in lookup evaluation
https://notcve.org/view.php?id=CVE-2021-45105
Apache Log4j2 versions 2.0-alpha1 through 2.16.0 (excluding 2.12.3 and 2.3.1) did not protect from uncontrolled recursion from self-referential lookups. This allows an attacker with control over Thread Context Map data to cause a denial of service when a crafted string is interpreted. This issue was fixed in Log4j 2.17.0, 2.12.3, and 2.3.1. Apache Log4j2 versiones 2.0-alpha1 hasta 2.16.0 (excluyendo las versiones 2.12.3 y 2.3.1) no protegían de la recursión no controlada de las búsquedas autorreferenciales. Esto permite a un atacante con control sobre los datos de Thread Context Map causar una denegación de servicio cuando es interpretada una cadena diseñada. • https://github.com/thedevappsecguy/Log4J-Mitigation-CVE-2021-44228--CVE-2021-45046--CVE-2021-45105--CVE-2021-44832 https://github.com/tejas-nagchandi/CVE-2021-45105 https://github.com/pravin-pp/log4j2-CVE-2021-45105 https://github.com/dileepdkumar/https-github.com-pravin-pp-log4j2-CVE-2021-45105-1 https://github.com/dileepdkumar/https-github.com-pravin-pp-log4j2-CVE-2021-45105 https://github.com/dileepdkumar/https-github.com-dileepdkumar-https-github.com-pravin-pp-log4j2-CVE-2021-45105-v htt • CWE-20: Improper Input Validation CWE-674: Uncontrolled Recursion •
