CVE-2024-0208: Denial of Service Vulnerability in Wireshark’s GVCP Dissector

Views: 503

Overview

CVE-2024-0208 is a significant vulnerability that affects Wireshark versions 4.2.0, 4.0.0 to 4.0.11, and 3.6.0 to 3.6.19. Wireshark, an open-source packet analyzer utilized by network administrators worldwide, has a vulnerability in its GigE Vision Control Protocol (GVCP) dissector. This vulnerability could allow an attacker to induce a denial-of-service (DoS) state via packet injection or by using a crafted capture file. The potential impact of this vulnerability includes system compromise and data leakage, posing a serious threat to both confidentiality and availability of data.

How the Exploit Works

This exploit works by leveraging the vulnerability in Wireshark’s GVCP dissector. An attacker sends specially crafted packets or a manipulated capture file to the target system running the affected Wireshark versions. These malicious packets or files cause the GVCP dissector to crash, leading to a denial of service. If further exploited, it can potentially lead to system compromise or data leakage.

Conceptual Example Code

Below is a conceptual example of how the vulnerability might be exploited. In this case, a malicious packet is sent to the target system:

POST /GVCP/dissector HTTP/1.1
Host: target.example.com
Content-Type: application/gvcp
{ "malicious_packet": "crafted_packet_that_crashes_dissector" }

This example shows a HTTP POST request sent to the endpoint where the GVCP dissector is located. The content of the request contains a malicious packet designed to crash the GVCF dissector, resulting in a denial of service.
Remember, this is only a conceptual example and in a real-world scenario, the actual malicious payload would be much more complex and specifically crafted to exploit the vulnerability in question.
