CVE-ID: CVE-2018-19349

CWE-ID: CWE-89 - Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')

Exploit availability: No

Description

The vulnerability allows a remote attacker to execute arbitrary SQL queries in database.

The vulnerability exists due to insufficient sanitization of user-supplied data in the admin_makehtml.php topic parameter due to mishandling in include/mkhtml.func.php.
