CVE-2021-44228 PoC — Apache Log4j2 JNDI features do not protect against attacker controlled LDAP and other JNDI related endpoints

Title:Apache Log4j2 JNDI features do not protect against attacker controlled LDAP and other JNDI related endpoints (CVE-2021-44228)
Description:Apache Log4j2 2.0-beta9 through 2.15.0 (excluding security releases 2.12.2, 2.12.3, and 2.3.1) JNDI features used in configuration, log messages, and parameters do not protect against attacker controlled LDAP and other JNDI related endpoints. An attacker who can control log messages or log message parameters can execute arbitrary code loaded from LDAP servers when message lookup substitution is enabled. From log4j 2.15.0, this behavior has been disabled by default. From version 2.16.0 (along with 2.12.2, 2.12.3, and 2.3.1), this functionality has been completely removed. Note that this vulnerability is specific to log4j-core and does not affect log4net, log4cxx, or other Apache Logging Services projects.

log4J burp被扫插件、CVE-2021-44228、支持RC1绕过、支持json数据类型、支持dnslog.cn和burp内置DNS、可配合JNDIExploit生成payload

在@pmiaowu fastjosn插件上做的修改，原作者用dnslog.cn进行出网检查，但在大型攻防演练（HW）过程中由于前期打点，测试的站点较多dnslog.cn会对IP进行封禁操作
导致插件无法正常检测

基础代码为@pmiaow完成 这里就不提供源码了
