CVE-2021-44228,log4j2 RCE Burp Suite Passive Scanner,and u can customize the ceye.io api or other apis,including internal networks

image

image

Two SRC(Security Response Center) sites were tested image

After loading,a url will appear,access it to see the dnslog request,of course,the plugin has its own DNS check record,this is only for the convenience of subsequent viewing image

characteristics:

0x01 Cookie、XFF、UA payload

0x02 Domain name based uniqueness,add host to dnslog payload

Plug ins mainly identify seven forms:

1.get method,a=1&b=2&c=3

2.post method,a=1&b=2&c=3

3.post method,{“a”:”1”,”b”:”22222”}

4.post method,a=1&param={“a”:”1”,”b”:”22222”}

5.post method,{"params":{"a":"1","b":"22222"}}

6.post method,body={"a":"1","b":"22222"}

7.post method,body={"params":{"a":"1","b":"22222"}}

if u need to test in the repeater

open dashbord→Live passive crawl from Proxy and Repeater→tick repeater

open dashbord→Live audit from Proxy and Repeater→tick repeater image
