CVE-2024-12356 - Critical Command Injection Vulnerability Discovered in Privileged Remote Access and Remote Support Products

A new critical vulnerability, identified as CVE-2024-12356, has been discovered affecting Privileged Remote Access (PRA) and Remote Support (RS) products. This vulnerability could enable an unauthenticated attacker to inject malicious commands that are executed as a site user. This blog post will discuss the details of the vulnerability, analyze the code snippet demonstrating the vulnerability, and provide links to the original references. Exploit details will also be covered to ensure that our readers are well-informed on how to protect their systems from potential attacks.

Background

Privileged Remote Access and Remote Support products are widely used throughout various industries, allowing system administrators to manage and troubleshoot systems remotely. These products play a crucial role in maintaining the operational efficiency and security of various systems. Unfortunately, the newly discovered CVE-2024-12356 vulnerability poses a significant threat to the integrity and confidentiality of these systems.

Vulnerability Details

The CVE-2024-12356 vulnerability allows an unauthenticated attacker to inject arbitrary commands that are executed as a site user. This can result in the compromise of sensitive system information, unauthorized access, or even disruption of the service. This critical vulnerability has a CVSS score of 9.1, indicating the high severity and potential impact on affected systems.

As the vulnerability exists in the PRA and RS products, it is essential to ensure that the latest patches are installed to defend against any potential attacks.

A simple code snippet demonstrating the vulnerability is as follows

def execute_command(input_cmd):
    os.system(input_cmd)

def parse_request(request):
    request_data = request.split('&')
    for data in request_data:
        if "cmd=" in data:
            return data.replace("cmd=", "")

input_request = "action=send_message&cmd=id"
parsed_cmd = parse_request(input_request)
if parsed_cmd:
    execute_command(parsed_cmd)

In the code example above, the execute_command function runs an input command using the os.system() functionality. The parse_request function processes incoming requests and extracts the command to be executed.

An attacker could craft a malicious request such as action=send_message&cmd=malicious_command to inject arbitrary commands that would be executed by the system.
