Description

Doctrine DBAL 3.x before 3.1.4 allows SQL Injection. The escaping of offset and length inputs to the generation of a LIMIT clause was not probably cast to an integer, allowing SQL injection to take place if application developers passed unescaped user input to the DBAL QueryBuilder or any other API that ultimately uses the AbstractPlatform::modifyLimitQuery API.

• 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.
