|
Attack Scenarios | An attacker can attempt to connect to a database supplying the user an overly long value. The result could permit the attacker to gain escalated privileges and run code of their choosing.
|
Ease of Attack | Simple.
|
Corrective Action | Ensure the system is using an up to date version of the software and has had all vendor supplied patches applied.
