Deeper analysis
A reflected cross-site scripting vulnerability exists in msaad1999's PHP-Login-System version 2.0.1. The flaw is present in the reset-password functionality, where the validator parameter is not properly sanitized before being reflected back to the user, allowing arbitrary JavaScript execution in the victim's browser. The issue is tracked as CWE-79 and carries a CVSS 3.1 score of 6.1.
Remote attackers can exploit the vulnerability without authentication by crafting a URL containing a malicious payload in the validator parameter and tricking an authenticated user into visiting it. Successful exploitation enables the attacker to execute JavaScript in the context of the affected application, potentially leading to session hijacking or theft of sensitive information displayed on the page.
The provided references consist of a public vulnerability-research repository that documents the finding; no official vendor advisory or patch information is included in the available sources.
