## Description

In the Admin Package Manager in Open Ticket Request System (OTRS) 5.0.0
through 5.0.24 and 6.0.0 through 6.0.1, authenticated admins are able to
exploit a Blind Remote Code Execution vulnerability by loading a crafted
opm file with an embedded CodeInstall element to execute a command on the
server during package installation. NOTE: the vendor disputes this issue
stating "the behaviour is as designed and needed for different packages to
be installed", "there is a security warning if the package is not verified
by OTRS Group", and "there is the possibility and responsibility of an
admin to check packages before installation which is possible as they are
not binary.
