Vulnerability description

Positive Research Center has discovered an SQL injection vulnerability in Help Request System.
Application incorrectly validates input data. That allows attackers to conduct SQL injection attack.

"SQL Injection" is a way to bypass network protection and attack the database. Settings transferred to the database through web applications are specially crafted to modify executable SQL query, for example, an attacker could execute additional query with the first one by adding different characters.

An attacker can use the vulnerability to obtain access to data which is normally unavailable or obtain system configuration data which can be used for further attacks. For example, modified query may return hashed user passwords which could be decrypted with brute force attack.
