Richard N. Hillegas commented on DERBY-7147:
--------------------------------------------
I'm done with the work I plan to do on this issue. We could work on a 10.16.2
release to publish the fix. But producing a release is a considerable amount of
work. In addition, year end is an awkward time to ask the community to vet a
new release. Maybe it makes sense to sweep up more fixes first and publish a
release in the spring.
I don't have a sense of how many Derby installations rely on LDAP.
Without an exploit, it's hard to gauge the severity of this bug. The only
exploit I can imagine is someone logging onto an LDAP-protected Derby
installation with a very strange name, which no one would choose for a real
user. I do not see a privacy or data corruption attack if GRANT/REVOKE
authorization is turned on. But the fake user would have the ability to create
databases and tables. That is, resource-exhaustion and denial-of-service
attacks might be possible.
What are your thoughts?

> An LDAP injection vulnerability has been identified in
> LDAPAuthenticationSchemeImpl.getDNFromUID(). An exploit has not been
> provided, but there is a possibility that an intruder could bypass
> authentication checks in Derby-powered applications which rely on external
> LDAP servers.
