###### Bypass WAFs by Shortening IP Address (by [0xInfection](https://twitter.com/0xInfection))
|
||
|
||
IP addresses can be shortened by dropping the zeroes:
|
||
|
||
```
|
||
http://1.0.0.1 → http://1.1
|
||
http://127.0.0.1 → http://127.1
|
||
http://192.168.0.1 → http://192.168.1
|
||
|
||
http://0xC0A80001 or http://3232235521 → 192.168.0.1
|
||
http://192.168.257 → 192.168.1.1
|
||
http://192.168.516 → 192.168.2.4
|
||
```
|
||
|
||
> This bypasses WAF filters for SSRF, open-redirect, etc where any IP as input gets blacklisted.

###### Generate CSR (metadata from existing certificate)
|
||
|
||
> Where `private.key` is the existing private key. As you can see you do not generate this CSR from your certificate (public key). Also you do not generate the "same" CSR, just a new one to request a new certificate.

|
||
```bash
|
||
( _fd="private.key" ; _fd_csr="request.csr" ; _fd_crt="cert.crt" ; \

|
||
host1> ssh -L 2250:nmap.org:443 localhost
|
||
|
||
# Connect to the service:
|
||
host1> curl -Iks --location -X GET https://localhost:2250
|
||
```
|
||
|
||
Example 2:
|
||
|
||
```bash
|
||
# Forwarding our local 9051 port to db.d.x:5432 from localhost through node.d.y
|
||
host1> ssh -nNT -L 9051:db.d.x:5432 node.d.y
|
||
|
||
# Connect to the service:
|
||
host1> psql -U db_user -d db_dev -p 9051 -h localhost
|
||
```
|
||
|
||
* `-n` - redirects stdin from `/dev/null`
|
||
* `-N` - do not execute a remote command
|
||
* `-T` - disable pseudo-terminal allocation
|

||
host1> ssh -nNT -R 9051:db.d.x:5432 node.d.y
|
||
|
||
# Connect to the service:

|
||
```bash
|
||
sed -n 10p /path/to/file
|
||
```
|
||
|
||
###### Remove a specific line from a file
|
||
|
||
```bash
|
||
sed -i 10d /path/to/file
|
||
# alternative (BSD): sed -i'' 10d /path/to/file
|
||
```
|
||
|
||
###### Remove a range of lines from a file
|
||
|
||
```bash
|
||
sed -i <file> -re '<start>,<end>d'
|
||
```
|
||
|
||
###### Replace newline(s) with a space
|
||
|
||
```bash
|
||
sed ':a;N;$!ba;s/\n/ /g' /path/to/file
|
||
|
||
# cross-platform compatible syntax:
|
||
sed -e ':a' -e 'N' -e '$!ba' -e 's/\n/ /g' /path/to/file
|
||
```
|
||
|
||
- `:a` create a label `a`
|
||
- `N` append the next line to the pattern space
|
||
- `$!` if not the last line, ba branch (go to) label `a`
|
||
- `s` substitute, `/\n/` regex for new line, `/ /` by a space, `/g` global match (as many times as it can)
|
||
|
||
Alternatives:
|
||
|
||
```bash
|
||
# perl version (sed-like speed):
|
||
perl -p -e 's/\n/ /' /path/to/file
|
||
|
||
# bash version (slow):
|
||
while read line ; do printf "%s" "$line " ; done < file
|
||
```
|
||
|
||
###### Delete string +N next lines
|
||
|
||
```bash
|
||
sed '/start/,+4d' /path/to/file
|
||
```

#### Shell Tricks [<sup>[TOC]</sup>](#anger-table-of-contents)
|
||
|
||
When you get a shell, it is generally not very clean, but after following these steps, you will have a fairly clean and comfortable shell to work with.
|
||
|
||
1) `script /dev/null -c bash`
|
||
2) Ctrl-Z (to send it to background)
|
||
3) `stty raw -echo; fg` (returns the shell to foreground)
|
||
4) `reset` (to reset terminal)
|
||
5) `xterm` (when asked for terminal type)
|
||
6) `export TERM=xterm; export SHELL=bash`
|
