Description Pedro Sampaio 2018-08-03 13:30:26 UTC 
It was found that in cobbler's XMLRPC API there are many places where the user supplied security token is not being correctly validated, effectively resulting in authentication being bypassed.

Comment 1 Cedric Buissart 2018-08-07 11:27:33 UTC 
Created cobbler tracking bugs for this issue:

Affects: epel-all [bug 1613293]
Affects: fedora-all [bug 1613292]
Comment 6 Cedric Buissart 2018-08-08 13:28:34 UTC 
Statement:

The most sensitive function not requiring a valid token is modify_settings(), which is not part of cobbler-2.0.7, the versions shipped Red Hat Enterprise Satellite 5. As such, the flaw is considered with a Medium severity rating on cobbler versions as shipped in Red Hat Enterprise Satellite 5. A future update may address this issue.
