Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection')

Summary

A cleverly devised username might bypass LDAP authentication checks in versions prior to 10.14.3, 10.15.0.x prior to 10.15.2.1, 10.16.0.x prior to 10.16.1.2, and 10.17.0.x prior to 10.17.1.0. 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. 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. Those are the releases which correspond, respectively, with Java LTS versions 17, 11, and 8.
