Overview
The CVE-2024-23815 vulnerability is a critical SQL injection flaw that affects Desigo CC server applications. The vulnerability has potential implications for any organization using Desigo CC, as it allows unauthenticated remote attackers to execute arbitrary SQL queries on the server database. This issue is particularly significant because of its potential for system compromise and data leakage.

Desigo CC | All versions (access from Installed Clients to Desigo CC server only allowed within highly protected zones)
How the Exploit Works
The vulnerability stems from the Desigo CC server application’s failure to authenticate specific client requests. An attacker can exploit this by modifying the client binary, which then allows the execution of arbitrary SQL queries on the server database via the event port. This could potentially enable an attacker to manipulate the database, extract sensitive data, or even gain unauthorized access to the system.
Conceptual Example Code
Below is a conceptual example of how an attacker might exploit this vulnerability using a malicious SQL query in a client request:
POST /eventport/4998/tcp HTTP/1.1
Host: target.example.com
Content-Type: application/x-www-form-urlencoded
{ "client_request": "DROP TABLE users;" }This malicious request attempts to delete a users table from the server database, effectively highlighting the destructive potential of this vulnerability.
