Running the web site through ZAP proxy with attack mode enabled reveals several pages. Viewing the response results for /login.html reveals a potential user name and password. We see the password is assigned the value [#undefined](#undefined "mention")[#undefined](#undefined "mention")RevereString".

![](/files/1arGcNK0F6uJhpaXvru2)

Using the command line we are able to reverse the string.

```bash
echo "<Password>" | rev
```
