FOOT Gestion - 'id' SQL Injection

source: https://www.securityfocus.com/bid/56862/info

FOOT Gestion is prone to an SQL-injection vulnerability because it fails to sufficiently sanitize user-supplied input before using it in an SQL query.

A successful exploit may allow an attacker to compromise the application, access or modify data, or exploit latent vulnerabilities in the underlying database.
