How the Exploit Works

The vulnerability lies within the mydetailsstudent.php endpoint of the Institute-of-Current-Students 1.0 software. Specifically, the myds GET parameter, which is designed to accept an email address as input and fetch the corresponding student’s personal information, fails to validate the identity or permissions of the requesting user. Thus, it allows both authenticated and unauthenticated attackers to manipulate the email value in the request URL and obtain sensitive student details.

Conceptual Example Code

Here’s a conceptual example of how the vulnerability might be exploited using a HTTP GET request:

GET /mydetailsstudent.php?myds=target-email@example.com HTTP/1.1
Host: vulnerable-institute.com

In this example, an attacker can simply replace “target-email@example.com” with the email address of any student they wish to target. The server will then respond with the personal details associated with that email address, leading to potential information disclosure.

Mitigation Guidance

The optimal solution to this vulnerability is to apply the vendor-supplied patch. Until the patch is applied, a Web Application Firewall (WAF) or Intrusion Detection System (IDS) could be used as a temporary mitigation measure. It is strongly advised to ensure that the identity and permissions of the requesting user are validated before returning personal information.
