Background
Apache DB DdlUtils is an open-source library designed to facilitate database schema manipulation and data migration. It provides a set of utilities and APIs for working with various database management systems. The library includes a feature called BinaryObjectsHelper, which was intended for migrating database data with SQL binary types. However, this feature was found to be insecure and vulnerable to deserialization attacks.
Vulnerability Detail
The BinaryObjectsHelper class in Apache DB DdlUtils 1.0 allowed untrusted data to be deserialized without proper validation. This means that an attacker could craft malicious serialized objects and exploit this vulnerability to execute arbitrary code on the target system. The impact of this vulnerability is severe, as it allows remote code execution and potential compromise of the entire system. The vulnerability has been assigned a CVSS score of 9.8 (Critical).
How To Fix
No fixed version is published for this vulnerability.
