Description
A flaw has been found in PHPGurukul Small CRM 4.0. Affected by this issue is some unknown functionality of the file /registration.php. Executing manipulation of the argument Username can lead to cross site scripting. It is possible to launch the attack remotely. The exploit has been published and may be used.
A stored cross-site scripting vulnerability has been identified in PHPGurukul Small CRM version 4.0. The issue resides in the registration module, specifically within the 'username' field of the '/registration.php' file. This vulnerability allows for the injection of persistent JavaScript payloads that are executed in the context of the administrator's browser session. The injected scripts can be used to steal session cookies and authentication tokens, perform unauthorized actions with elevated privileges, deliver phishing or malware through the admin panel, and potentially compromise CRM data or lead to a system takeover.
It is recommended to apply output encoding to user inputs before rendering them in the HTML context of admin pages. Additionally, input validation and sanitization should be implemented to allow only safe characters, rejecting or sanitizing any malicious patterns.
