## Recon

The same box from `Goober 1` still exposes SSH on `22/tcp` and `uftpd 2.9` on `10921/tcp`.

Anonymous FTP works, and `uftpd 2.9` is vulnerable to path traversal through `RETR`, so fetching `../../home/jimbo/.bash_history` reveals `jimbo`'s password:

```text
mysql -u jimbo -pADFwPAcHDNCSGoyCwik6
```

## Solve

SSH in as `jimbo` with that password and list the home directory. The challenge hint is literal: there is no root-only flag to recover. `flag2.txt` sits directly in `jimbo`'s home and is readable by `jimbo`.

```text
/home/jimbo/flag2.txt
```

Reading the file gives the challenge flag:

```text
CIT{Br41n_bLa$t3R}
```

## Flag

```text
CIT{Br41n_bLa$t3R}
```
