CVSS: 9.8EPSS: 15%CPEs: 42EXPL: 3CVE-2022-23305 – SQL injection in JDBC Appender in Apache Log4j V1
https://notcve.org/view.php?id=CVE-2022-23305
18 Jan 2022 — 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... • https://github.com/HynekPetrak/log4shell-finder • 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
18 Jan 2022 — 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.

18 Dec 2021 — 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.... • https://github.com/thedevappsecguy/Log4J-Mitigation-CVE-2021-44228--CVE-2021-45046--CVE-2021-45105--CVE-2021-44832 • CWE-20: Improper Input Validation CWE-674: Uncontrolled Recursion •

14 Dec 2021 — 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.

27 Apr 2020 — 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.
