How the Exploit Works
The vulnerability CVE-2025-5086 exploits a weakness in the deserialization process of untrusted data in DELMIA Apriso. Deserialization is the process of converting data from a flat file or a database into an object. If an attacker can control the data that is being deserialized, they can manipulate it to execute arbitrary code on the server. This can lead to a variety of malicious outcomes, including system compromise and data leakage.
Conceptual Example Code
Below is a conceptual example of how an attacker might exploit this vulnerability. The malicious payload is sent via a POST request to a vulnerable endpoint:
POST /vulnerable/endpoint HTTP/1.1
Host: target.example.com
Content-Type: application/json
{ "malicious_payload": "malicious serialized data" }In this example, `malicious serialized data` is a serialized object containing malicious code. When the server deserializes this object, the malicious code is executed.
Mitigation Guidance
To mitigate this vulnerability, it is recommended to apply the vendor patch as soon as it is available. In the meantime, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can serve as temporary mitigation. It’s also a good practice to limit the exposure of the application to untrusted sources, and to impose strict input validation and filtering on the deserialization process.
