A vulnerability has been discovered in BigProf Online Invoicing System 2.6, which does not sufficiently encode user-controlled input, resulting in persistent XSS through /inventory/items_view.php, in the FirstRecord parameter. Exploitation of this vulnerability could allow an attacking user to store dangerous JavaScript payloads on the system that will be triggered when the page loads.

BigProf Online Invoicing System before 3.0 offers a functionality that allows an administrator to move the records of members across groups. The applicable endpoint (admin/pageTransferOwnership.php) lacks CSRF protection, resulting in an attacker being able to escalate their privileges to Administrator and effectively taking over the application.

BigProf Online Invoicing System before 2.9 suffers from an unauthenticated SQL Injection found in /membership_passwordReset.php (the endpoint that is responsible for issuing self-service password resets). An unauthenticated attacker is able to send a request containing a crafted payload that can result in sensitive information being extracted from the database, eventually leading into an application takeover. This vulnerability was introduced as a result of the developer trying to roll their own sanitization implementation in order to allow the application to be used in legacy environments.

BigProf Online Invoicing System before 4.0 fails to adequately sanitize fields for HTML characters upon an administrator using admin/pageEditGroup.php to create a new group, resulting in Stored XSS. The caveat here is that an attacker would need administrative privileges in order to create the payload. One might think this completely mitigates the privilege-escalation impact as there is only one high-privileged role. However, it was discovered that the endpoint responsible for creating the group lacks CSRF protection.

BigProf Online Invoicing System before 3.1 fails to correctly sanitize an XSS payload when a user registers using the self-registration functionality. As such, an attacker can input a crafted payload that will execute upon the application's administrator browsing the registered users' list. Once the arbitrary Javascript is executed in the context of the admin, this will cause the attacker to gain administrative privileges, effectively leading into an application takeover. This affects app/membership_signup.php and app/admin/pageViewMembers.php.

BigProf Online Invoicing System (OIS) through 2.6 has XSS that can be leveraged for session hijacking. An attacker can exploit the XSS vulnerability, retrieve the session cookie from the administrator login, and take over the administrator account via the Name field in an Add New Client action.
