A vulnerability has been identified in OZW672 (All versions < V6.0), OZW772 (All versions < V6.0). The web service of affected devices is vulnerable to SQL injection when checking authentication data. This could allow an unauthenticated remote attacker to bypass the check and authenticate as Administrator user.
The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.
