How the Exploit Works

The vulnerability arises from a missing authorization check in the affected Ivanti products. An authenticated user with read-only admin privileges can exploit this flaw by sending a specially crafted request to the server. Since the server does not adequately verify the user’s permissions before processing the request, the attacker can modify authentication-related settings. This manipulation could potentially grant them higher privileges or even full control of the system.

Conceptual Example Code

Here’s a conceptual example, in the form of an HTTP request, of how the vulnerability might be exploited:

PATCH /api/configure/authentication HTTP/1.1
Host: target.example.com
Content-Type: application/json
Authorization: Bearer [Insert Auth Token]
{ "admin_privileges": "full_control" }

In this example, the attacker is sending a PATCH request to the `configure/authentication` endpoint. The request aims to change the `admin_privileges` setting to “full_control”. Since the server doesn’t properly check the user’s authorization, it accepts and processes this request, potentially granting the attacker full control of the system.

Conceptual Example Code

Here is a conceptual example of how the vulnerability might be exploited:

GET /existing/html5/connection HTTP/1.1
Host: target.example.com
Authorization: Bearer {legitimate_token}
// The attacker intercepts the above request, then sends a new request:
GET /existing/html5/connection HTTP/1.1
Host: target.example.com
Authorization: Bearer {hijacked_token}

In this example, the attacker intercepts a legitimate request, then reuses the hijacked token to send a new request, effectively hijacking the existing HTML5 connection.

Mitigation Guidance

The vendor, Ivanti, has provided a patch to fix this vulnerability. The patch should be applied as soon as possible on all affected systems. If immediate patching is not possible, use of a web application firewall (WAF) or intrusion detection system (IDS) can serve as temporary mitigation, helping to detect and block attempts to exploit this vulnerability.

How the Exploit Works

This vulnerability occurs due to the software’s improper handling of deserialization of untrusted data. In simple terms, deserialization is the process of converting data from a format suitable for storage or transmission back to a format usable for further processing. If an attacker can control the format and contents of the data being deserialized, they can manipulate the processing to serve their malicious intents.
In this case, an attacker could exploit the vulnerability by injecting malicious data into the system, which then gets deserialized by the ThemeGoods Photography software. The vulnerability enables the malicious data to bypass the system’s security checks, potentially leading to system compromise or data leakage.

Conceptual Example Code

The following conceptual example demonstrates how an attacker might exploit this vulnerability. Note that this is a simplified example and actual attacks might be more complex.

POST /themeGoods/photography HTTP/1.1
Host: target.example.com
Content-Type: application/json
{ "malicious_payload": "Serialized_Object_with_Malicious_Code" }

In this example, the attacker sends a POST request to the server hosting the ThemeGoods Photography software. They include a malicious serialized object in the request body, which then gets deserialized by the server, potentially leading to the execution of the malicious code contained in the payload.
