How the Exploit Works

The vulnerability is rooted in the improper handling of user input during web page generation. This oversight allows attackers to inject malicious scripts into web pages, which are then executed in the browsers of users visiting these pages. These scripts can hijack user sessions, deface websites, or redirect the user to malicious sites.

Conceptual Example Code

A potential exploitation of this vulnerability might look like this:

POST /vulnerable/endpoint HTTP/1.1
Host: target.example.com
Content-Type: application/json
{ "userInput": "<script>malicious_code_here</script>" }

In this example, the attacker sends a POST request to a vulnerable endpoint with a payload containing a malicious script. When this input is improperly neutralized and reflected on the web page, the script executes in the user’s browser.

Mitigation

Users and administrators are advised to apply the vendor-supplied patch as soon as possible. As a temporary measure, users can employ a web application firewall (WAF) or an intrusion detection system (IDS) to filter out malicious inputs and protect against potential exploits. However, these measures should not replace the permanent solution of patching the system.

Conceptual Example Code

The following is a conceptual example of how the vulnerability might be exploited. In this instance, a malicious office document is created and sent to the victim:

# Create a malicious office document
$ echo "Buffer overflow payload" > malicious.docx
# Send the document to the victim
$ mail -s "Important Document" victim@example.com < malicious.docx

Upon opening the document, the payload triggers a buffer overflow in the affected macOS system causing an unexpected application termination or potential arbitrary code execution.

Mitigation Guidance

Users are strongly urged to apply the vendor patch as soon as it is available. Until then, using a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) can serve as temporary mitigation. These systems can detect and prevent buffer overflow attempts, providing some level of protection against this vulnerability.

An attacker could exploit this vulnerability by manipulating the DataSize and VariableNameSize values to execute malicious code or gain unauthorized access to data. This could compromise the system or lead to data leakage.

Conceptual Example Code

Below is a conceptual example of how this vulnerability might be exploited. In this pseudocode, the attacker manipulates the DataSize and VariableNameSize values:

#include <insydeh2o.h>
void exploit() {
uint32_t dataSize = 0xFFFFFFFF; // Manipulated size
uint32_t variableNameSize = 0xFFFFFFFF; // Manipulated size
// Request data with manipulated sizes
InsydeH2O_GetVariable(variableName, &variableNameSize, NULL, &dataSize, data);
}

This example is purely illustrative and provides a basic understanding of how the vulnerability might be exploited. It’s important to note that real-world exploits would be far more complex and potentially devastating.

Affected Products

Product | Affected Versions

Intel(R) PROSet/Wireless WiFi Software for Windows | Versions before 23.100

How the Exploit Works

The vulnerability is a stack-based buffer overflow. This implies that an attacker can overrun the buffer’s boundary and overwrite adjacent memory locations, by providing input that exceeds a process’s stack, which is used for static storage of variables. This could potentially allow the attacker to manipulate the application’s data and control flow, which could be leveraged to execute arbitrary code, thereby compromising the system or causing a denial of service.

Conceptual Example Code

Here is a conceptual example of how such a vulnerability might be exploited. Please note that this is a highly simplified version of what a real exploit would look like, and is intended for illustrative purposes only.

# Exploit pseudocode
def exploit():
buffer = create_buffer_size(1024)
payload = create_malicious_payload(2048) # Larger than the buffer size
# Overwrite the buffer with the payload
for i in range(len(payload)):
buffer[i] = payload[i]
# Execute the buffer as code
execute(buffer)
exploit()

In this hypothetical exploit, the malicious payload is intentionally larger than the buffer, causing an overflow. This overflow can then be leveraged to execute arbitrary code on the system.
