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. Note this issue only affects Log4j 1.x when specifically configured to use JMSSink, which i... • http://www.openwall.com/lists/oss-security/2022/01/18/3 • CWE-502: Deserialization of Untrusted Data •
