Hr Portal EUVD-2025-17102

The vulnerability resides in CWE-502 (Deserialization of Untrusted Data), a class of flaw where applications deserialize serialized objects from untrusted sources without proper validation. In this case, the Soar Cloud HRD 'download file function' accepts serialized objects (likely Java serialized objects or similar binary formats) and deserializes them directly. An attacker crafts a malicious serialized object containing gadget chains (common Java deserialization gadgets from libraries like Apache Commons Collections, Spring Framework, or similar) that trigger arbitrary command execution during object instantiation. The affected product is Soar Cloud HRD (CPE context: enterprise HR management platform), which processes file downloads and likely uses a serialization framework for inter-component communication or state management. The lack of input validation or signature verification on serialized data allows the attack to succeed.
