Browser script execution via unneutralized URL input

Published Jul 7, 2023 · Updated Aug 2, 2024

Reflected cross-site scripting in SimplePHPscripts Funeral Script PHP 3.1 allows remote authenticated users to run script via /preview.php. The URL Parameter Handler reflects an unspecified user-controlled URL value into the generated page without neutralizing script syntax. A victim must open the crafted request; successful exploitation executes attacker-supplied browser script in the application's origin, with no reported availability impact.
