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 •
