In the world of cybersecurity, it's crucial to stay informed and up to date on the latest vulnerabilities, exploits, and patches. Recently, a new security vulnerability has been discovered, labeled CVE-2024-20148, affecting Wlan STA (Station) FW (Firmware). This vulnerability is an out-of-bounds write issue caused by improper input validation, which could potentially lead to some severe consequences if exploited.

In this long-read post, we'll provide an in-depth analysis of this vulnerability, including code snippets, links to original references, and exploit details. We hope that by sharing this information, we can empower users, developers, and administrators to better understand and protect themselves against potential threats.

What is the Vulnerability?

The CVE-2024-20148 vulnerability resides in the Wlan STA FW, where it is possible for an out-of-bounds write to occur due to improper input validation. When exploited, this could lead to remote code execution with no additional execution privileges needed. Even more concerning, user interaction is not required for exploitation, meaning an attacker could potentially compromise a system without the owner's knowledge simply by being in proximity or adjacent to the target device.

To address this vulnerability, the following patch has been issued

- Patch ID: WCNCR00389045 / ALPS09136494

Exploit Details

To further understand the potential impact of CVE-2024-20148, let's delve into the exploit details and code snippets associated with this vulnerability.

Code Snippet and Exploit

While specifics about the exploit code are not publicly available in order to protect systems from being compromised, we can discuss the basic premise of how the vulnerability might work. The issue stems from improper input validation, which could allow an attacker to send a specially crafted packet to the target device. This malformed packet could then trigger an out-of-bounds write, potentially leading to remote code execution.

Example of how the exploit might work

// Attacker sends a specially crafted packet to the target device
payload = create_malformed_packet();

// The target device's Wlan STA FW processes the packet
process_packet(payload);

// Improper input validation leads to an out-of-bounds write
memcpy(destination_buffer, payload, payload_size);

// Remote code execution occurs
execute_remote_code(buffer);

Again, we must emphasize that this is a highly simplified example and the actual code for exploiting this vulnerability would be more complex.
