CVE-2022-23305CRITICAL | SQL injection in JDBC Appender in Apache Log4j V1By 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, … CWE-89Jan 18, 2022 | CVSS9.8v3.1 | EPSS66.5% | PoCs3 | SignalsNot listed in CISA KEVNo known ransomware useNo Nuclei templates | STIX |
CVE-2022-23302HIGH | Deserialization of untrusted data in JMSSink in Apache Log4j 1.xJMSSink 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 JMSS… CWE-502Jan 18, 2022 | CVSS8.8v3.1 | EPSS63.6% | PoCs0 | SignalsNot listed in CISA KEVNo known ransomware useNo Nuclei templates | STIX |
CVE-2021-4104HIGH | Deserialization of untrusted data in JMSAppender in Apache Log4j 1.2JMSAppender 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 o… CWE-502Dec 14, 2021 | CVSS7.5v3.1 | EPSS81.1% | PoCs4 | SignalsNot listed in CISA KEVNo known ransomware useNo Nuclei templates | STIX |
CVE-2019-17571CRITICAL | Deserialization of Untrusted Data in Log4jIncluded in Log4j 1.2 is a SocketServer class that is vulnerable to deserialization of untrusted data which can be exploited to remotely execute arbitrary code when combined with a deserialization gadget when listening to untrusted network traffic for log data. This affects Log4j versions up to 1.2 up to 1.2.17. CWE-502Dec 20, 2019 | CVSS9.8v3.1 | EPSS69.1% | PoCs3 | SignalsNot listed in CISA KEVNo known ransomware useNo Nuclei templates | STIX |
