标题:Apache Log4j 代码问题漏洞 (CVE-2021-44228)
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 存在代码问题漏洞，攻击者可设计一个数据请求发送给使用 Apache Log4j工具的服务器，当该请求被打印成日志时就会触发远程代码执行。
Description
Rapidly scan filesystems for Java programs potentially vulnerable to Log4Shell (CVE-2021-44228) or "that Log4j JNDI exploit" by inspecting the class paths inside files
介绍
# log4shelldetect

Scans a file or folder recursively for Java programs that may be vulnerable to:

- CVE-2021-44228 (Log4Shell) (v2.0.x - v2.14.x)
- CVE-2021-45046 (v2.15.x)
- CVE-2021-45105 (v2.16.x)[^*]

[^*]: 2.12.2 detection is not available yet pending 2.12.3's release which I will need to test. 2.12.2 will appear as patched.

by inspecting the class paths inside files.

If you only want possibly vulnerable files to be printed rather than all files, run with `-mode list`.
