Weaknesses
CWE · root cause- CWE-1027OWASP Top Ten 2017 Category A1 - InjectionWeaknesses in this category are related to the A1 category in the OWASP Top Ten 2017.
- 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.
