A vulnerability was found in Netentsec NS-ASG Application Security Gateway 6.3. It has been declared as critical. This vulnerability affects unknown code of the file /protocol/iscuser/uploadiscuser.php of the component JSON Content Handler. The manipulation of the argument messagecontent leads to sql injection. The attack can be initiated remotely. The exploit has been disclosed to the public and may be used. The identifier of this vulnerability is VDB-266848. NOTE: The vendor was contacted early about this disclosure but did not respond in any way.
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.
