Description Pedro Sampaio 2018-03-16 19:55:11 UTC
UnboundID LDAP SDK version from commit 801111d8b5c732266a5dbd4b3bb0b6c7b94d7afb up to commit 8471904a02438c03965d21367890276bc25fa5a6, where the issue was reported and fixed, contains an Incorrect Access Control vulnerability in process function in SimpleBindRequest class which doesn't check for empty password when running in synchronous mode. That can result in the ability to impersonate any valid user. This attack appear to be exploitable via Providing valid username and empty password against servers that do not do additional validation as per https://tools.ietf.org/html/rfc4513#section-5.1.1.

Comment 1 Pedro Sampaio 2018-03-16 19:55:59 UTC
Created unboundid-ldapsdk tracking bugs for this issue:

Affects: fedora-all [bug 1557532]

Comment 2 Doran Moppert 2018-03-20 02:11:30 UTC
Statement:

Red Hat Enterprise Virtualization does not use the UnboundID SDK in synchronous mode, and hence does not expose this vulnerability in its default configuration.

Comment 6 Doran Moppert 2018-05-01 05:51:30 UTC
Sparks,

one for review:  https://errata.devel.redhat.com/advisory/33225

Note the tracker here has also been used for rebase, hence it looks odd.

Ignore #28793, I expect that to be dropped as it's the very same build.  Emailing with Sandro to sort that out.
