Summary

A carefully crafted username can exploit a vulnerability in LDAP authentication checks in Apache Derby. This flaw allows an attacker to create excessive Derby databases, potentially exhausting disk space. Furthermore, with proper privileges, the attacker could execute malicious code linked to the Derby server account. If the LDAP-protected database lacks strong SQL authorization controls, it opens pathways for unauthorized access, enabling attackers to view, manipulate sensitive data, and execute critical database functions. To mitigate this risk, it is advised to upgrade to Java 21 and Derby 10.17.1.0 or consider building a custom Derby distribution based on earlier versions with applied fixes.

Affected Version(s)

Apache Derby 10.1.1.0 <= 10.1.3.1

Apache Derby 10.2.1.6 <= 10.2.2.0

Apache Derby 10.3.1.4 <= 10.3.3.0
