How the Exploit Works
The vulnerability exploits the deserialization of untrusted data in Awethemes Hillter. Deserialization is a process that converts byte streams into objects. In this case, an attacker can manipulate the byte stream to create malicious objects. When the server deserializes these objects, it can lead to object injection, where the attacker’s code is executed within the application’s context.
Conceptual Example Code
An example of how this vulnerability might be exploited is by sending a malicious payload to a vulnerable endpoint. This could look something like the following:
POST /vulnerable/endpoint HTTP/1.1
Host: target.example.com
Content-Type: application/json
{ "malicious_payload": "SerializedObjectWithInjectedCode" }In this example, `SerializedObjectWithInjectedCode` is a serialized object that contains malicious code. When the server deserializes this object, the malicious code is executed.
Mitigation Steps
To mitigate this vulnerability, users are advised to apply the vendor-provided patch immediately. As a temporary measure, users can deploy a Web Application Firewall (WAF) or Intrusion Detection Systems (IDS) to detect and prevent exploit attempts. However, this is only a temporary solution and users should apply the vendor’s patch as soon as possible to fully secure their systems.
