DescriptionCVE.org

A cross-site scripting (XSS) vulnerability exists in the Blood Bank Management System 1.0 within the login.php component. The application fails to properly sanitize or encode user-supplied input before rendering it in response. An attacker can inject malicious JavaScript payloads into the msg and error parameters, which are then executed in the victim's browser when the page is viewed.

Analysis

Technical ContextAI

Cross-site scripting (XSS) allows injection of client-side scripts into web pages viewed by other users due to insufficient output encoding.

RemediationAI

Encode all user-supplied output contextually (HTML, JS, URL). Implement Content Security Policy (CSP) headers. Use HTTPOnly and Secure cookie flags.
