A cleverly devised username might bypass LDAP authentication checks. In
LDAP-authenticated Derby installations, this could let an attacker fill up
the disk by creating junk Derby databases. In LDAP-authenticated Derby
installations, this could also allow the attacker to execute malware which
was visible to and executable by the account which booted the Derby server.
In LDAP-protected databases which weren’t also protected by SQL
GRANT/REVOKE authorization, this vulnerability could also let an attacker
view and corrupt sensitive data and run sensitive database functions and
procedures. Mitigation: Users should upgrade to Java 21 and Derby
10.17.1.0. Alternatively, users who wish to remain on older Java versions
should build their own Derby distribution from one of the release families
to which the fix was backported: 10.16, 10.15, and 10.14. Those are the
releases which correspond, respectively, with Java LTS versions 17, 11, and
8.
