Readycheck to confirm it

PrismaWEB is susceptible to credential disclosure. The vulnerability exists due to the disclosure of hard-coded credentials allowing an attacker to effectively bypass authentication of PrismaWEB with administrator privileges. The credentials can be disclosed by simply navigating to the login_par.js JavaScript page that holds the username and password for the management interface that are being used via the Login() function in /scripts/functions_cookie.js script.

Impact

An attacker could gain unauthorized access to the application and potentially compromise user accounts and sensitive data.

Fix

Ensure that sensitive credentials are properly protected and not exposed in the application's source code or configuration files.

How to confirm it

Send: GET {{BaseURL}}/user/scripts/login_par.js
Positive when: contains "txtChkUser" and "txtChkPassword" AND status 200
