A Cross-Site Request Forgery (CSRF) vulnerability exists in the code astro Internet Banking System version 2.0.0, which allows remote attackers to perform unauthorized actions on behalf of authenticated users, such as administrators, without their knowledge. By crafting a malicious HTML page, an attacker can trick an authenticated user (such as an admin) into submitting a request to modify sensitive account details (e.g., name, email) on the target system. This vulnerability arises due to the lack of CSRF protection on the account modification page (e.g., pages_account.php), allowing an attacker to bypass security mechanisms and execute unauthorized actions on the user's behalf.
