Until a fix is available, administrators should avoid running the affected subcommands with elevated privileges or restrict jailed user capabilities to prevent exploitation.
Description
Bastille versions through 1.4.4 have a symlink following vulnerability in the cp.sh, rcp.sh, and jcp.sh subcommands. This flaw allows jailed users to escape their jail isolation by planting symbolic links that cause administrator-run copy operations to overwrite or read host files with root privileges.
