CVE-2022-46337

Technical Description

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.

Remediation

Check the references section for vendor advisories and patches from apache. Update derby to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
