# Dockwatch Remote Command Execution
#
# Jeremy Brown [jbrown3264/gmail] / Sept 2024
#
# Intro
#
# Dockwatch is a container management web UI for docker. It runs by default
# without authentication, although guidance is available for how to setup
# credentials for access. It has a Commands feature that allows a user to
# run docker commands such as inspect, network, ps. Prior to fix, it did not
# restrict input for parameters, so both 'container' and 'parameters' for the
# 'dockerInspect' command were vulnerable to shell command injection on the
# container as the 'abc'user with (limited) command output.
#
# Example
#
# $ ./dockexec.py http://host:9999 "id"
# uid=1001(abc)
# gid=131(abc)
# groups=131(abc),281(unraiddocker),1000(users)
#
# Workaround: echo "admin:[a-FANTASTIC-password]" > /config/logins
# * DO NOT DO THIS: echo "" > /config/logins (* unless you want spacebar to work for user/pass)
#
# Fix: see commits 23df366 and c091e4c, kudos for maintainers for quick fixes
#
