Deeper analysis
CVE-2025-70141, published on 2026-02-18T17:21:35.700, is an incorrect access control vulnerability affecting SourceCodester Customer Support System 1.0. The issue resides in ajax.php, where the AJAX dispatcher does not enforce authentication or authorization before invoking administrative methods in admin_class.php based on the action parameter. This flaw, linked to CWE-306 (Missing Authentication for Critical Function) and CWE-862 (Missing Authorization), has a CVSS v3.1 base score of 9.4 (AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:H/A:H).
An unauthenticated remote attacker can exploit this vulnerability over the network with low complexity and no privileges required. By sending crafted requests with specific action parameters, the attacker can perform sensitive administrative operations, including creating customers, deleting users (such as the admin account), and modifying or deleting other application records like tickets, departments, and comments, resulting in unauthorized data modification.

Directly requires the AJAX dispatcher to enforce authentication and authorization before invoking sensitive administrative methods in admin_class.php based on the action parameter.
Ensures least privilege restricts unauthenticated attackers from performing administrative operations like creating customers, deleting users, or modifying records.
Mandates access control decision logic to authorize requests prior to dispatching action parameters to administrative functions, preventing unauthorized execution.
