From c12a52f0d78b30931713a3548b22e799d41f3622 Mon Sep 17 00:00:00 2001 From: Fraser Tweedale Date: Dec 14 2016 17:08:33 +0000 Subject: certprofile-mod: correctly authorise config update Certificate profiles consist of an FreeIPA object, and a corresponding Dogtag configuration object. When updating profile configuration, changes to the Dogtag configuration are not properly authorised, allowing unprivileged operators to modify (but not create or delete) profiles. This could result in issuance of certificates with fraudulent subject naming information, improper key usage, or other badness. Update certprofile-mod to ensure that the operator has permission to modify FreeIPA certprofile objects before modifying the Dogtag configuration. https://fedorahosted.org/freeipa/ticket/6560 Reviewed-By: Jan Cholasta --- diff --git a/ipaserver/plugins/certprofile.py b/ipaserver/plugins/certprofile.py index f446607..2bd3311 100644 --- a/ipaserver/plugins/certprofile.py +++ b/ipaserver/plugins/certprofile.py @@ -310,6 +310,11 @@ class certprofile_mod(LDAPUpdate): raise errors.ProtectedEntryError(label='certprofile', key=keys[0], reason=_('Certificate profiles cannot be renamed')) if 'file' in options: + # ensure operator has permission to update a certprofile + if not ldap.can_write(dn, 'ipacertprofilestoreissued'): + raise errors.ACIError(info=_( + "Insufficient privilege to modify a certificate profile.")) + with self.api.Backend.ra_certprofile as profile_api: profile_api.disable_profile(keys[0]) try:
