📆 Changelog

[29th Febuary 2024] - Bugs & Feature Request (thanks to @cbartholomew)

• The packet length will now adjust to ensure all file names will be uploaded with the correct packet lengths. i.e. works with more than just /etc/passwd or 11 character file lenghts.
• Added -c COMMAND which allows the testing of other jenkins-cli.jar commands: who-am-i,connect-node. Default remains "help".
• Added -l LANGUAGE which allows for the 5 byte language code, i.e. en_US, cn_ZH, etc. The default is en_US.

[27th January 2024] - Feature Request

• Added scanning/exploiting via input file with hosts (-i INPUT_FILE).
• Added export to file (-o OUTPUT_FILE).

[26th January 2024] - Initial Release
