A recently discovered vulnerability, known as CVE-2024-55160, affects certain versions of the GFast software. The vulnerability is an SQL injection that can be executed through the OrderBy parameter found at the /system/operLog/list path. This post aims to provide an in-depth understanding of this vulnerability, the specific GFast versions impacted, the relevant code snippets, and the potential exploit details. For original references, we'll also include links to authoritative sources.

Affected Versions

The CVE-2024-55160 SQL injection vulnerability has been discovered in GFast versions 2 to 3.2. Developers using these versions should consider upgrading or implementing security patches to mitigate potential risks.

Details and Exploit

The vulnerability lies in the way GFast handles the OrderBy parameter at the /system/operLog/list path. By manipulating the OrderBy parameter, malicious users can exploit this flaw, allowing them to execute arbitrary SQL commands and potentially access sensitive information or manipulate the database.

In the affected versions, the relevant code snippet is as follows

def list(request):
    # Other code
    orderby = request.GET.get('OrderBy', 'id DESC')
    logs = Logs.objects.extra(select={'datetime':
                                      'strftime("%%Y-%%m-%%d %%H:%%M:%%S",
                                      time_created)'},
                              order_by=(orderby,)).filter(**search_dict)
    # Other code

In the snippet above, the OrderBy parameter is received directly from the GET request, and no sanitation or validation is performed on this parameter before it is passed to the database's query.

Proof of Concept

An example of how an attacker could exploit this vulnerability is by sending a malicious GET request to the target application. For example:

http://target.com/system/operLog/list?OrderBy=id;%20DELETE%20FROM%20users

In this request, the attacker is providing an SQL command to delete all records from the users' table after the id field. As the OrderBy parameter is not sanitized or validated, the application executes this command.

Mitigation Measures

Developers should consider implementing the following measures as a means to address this vulnerability:

Sanitize and validate the OrderBy parameter using parameterized queries or prepared statements.

3. Implement robust input validation functions to restrict the range of acceptable inputs for critical parameters, such as the OrderBy parameter in this case.

Conclusion

The SQL injection vulnerability CVE-2024-55160 in GFast versions 2 to 3.2 serves as a reminder for developers to maintain good coding practices. Ensuring that all input parameters are sanitized and validated reduces the chances for such critical vulnerabilities to exist within your software. Furthermore, staying updated with patches and new software releases is crucial in maintaining a secure and stable system.
