SQL injection in Netentsec NS-ASG Application Security Gateway 6.3 allows remote authenticated users to alter database queries. The JSON handler passes each UserId extracted from messagecontent directly into an SQL statement without validation or parameterization. A valid session cookie reaches the endpoint, and injected statements can read or modify data held by the appliance database.
