Description

Improper neutralization of special elements used in an SQL command (“SQL Injection”) in SonicWall SMA1000 series appliances allows a remote authenticated attacker with read-only administrator privileges to escalate privileges to primary administrator.

• CWE-89Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')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.
