Description

An improper neutralization of special elements used in an SQL command ('SQL Injection') vulnerability [CWE-89] vulnerability in Fortinet FortiWeb 7.6.0 through 7.6.3, FortiWeb 7.4.0 through 7.4.7, FortiWeb 7.2.0 through 7.2.10, FortiWeb 7.0.0 through 7.0.10 allows an unauthenticated attacker to execute unauthorized SQL code or commands via crafted HTTP or HTTPs requests.

• 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.
