Title: GreenSQL Firewall WHERE Clause Secuity Bypass Vulnerability
Severity: HIGH
Description:
GreenSQL Firewall is a database firewall application.
GreenSQL Firewall is prone to a security-bypass vulnerability because the application allows attackers to bypass the SQL-injection protection via a WHERE clause. Specifically, if the clause contains an expression such as 'x=y=z', an attacker can bypass SQL-injection protection.
Successful exploits may aid in SQL attacks on the underlying application.
Affected Products:
- GreenSQL GreenSQL 0.9.2
- GreenSQL GreenSQL 0.9.4
