How the Exploit Works

The exploit takes advantage of the hard-coded credentials in UNI-NMS-Lite. An attacker can use these credentials to gain unauthorized access to the managed database. Without the need for user interaction or any special privileges, the attacker can read, manipulate, and create entries in the database. This could lead to a range of malicious activities including data theft, data manipulation, or potentially even system compromise.

Conceptual Example Code

Here is a conceptual example of how the vulnerability might be exploited, in this case via a simple HTTP GET request to the target system:

GET /database/endpoint HTTP/1.1
Host: target.example.com
Authorization: Basic [hard-coded credentials]

In this example, the “hard-coded credentials” would be replaced with the actual credentials hardcoded into the system. Such a request could allow the attacker to read, update, or create entries in the managed database.
