How the Exploit Works

The vulnerability lies in the deserialization of untrusted data in Apache InLong. An attacker can exploit this vulnerability by sending specially crafted data to the application, which then deserializes this data. The exploitation involves the use of the MySQL driver to execute an arbitrary file read attack. This could potentially lead to unauthorized access to sensitive data or even full system compromise.

Conceptual Example Code

Here’s a conceptual example of how the vulnerability might be exploited, using a malicious payload sent over HTTP:

POST /vulnerable/endpoint HTTP/1.1
Host: target.example.com
Content-Type: application/json
{ "malicious_payload": "{__type__:'java.lang.Runtime',__value__:'getRuntime().exec(\"read arbitrary file\")'}" }

Please note, the above is just a conceptual example and does not represent the actual exploit code. The actual exploit could vary significantly and may involve complex manipulations.

Mitigation

Users are advised to upgrade to Apache InLong’s 1.10.0 version or apply the patch provided in the link [1] to mitigate this vulnerability. Alternatively, the use of a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can serve as a temporary mitigation measure until the patch can be applied.
