An issue was discovered in SugarCRM Enterprise before 11.0.6 and 12.x before 12.0.3. Two SQL Injection vectors have been identified in the REST API. By using crafted requests, custom SQL code can be injected through the REST API because of missing input validation. Regular user privileges can use used for exploitation. Editions other than Enterprise are also affected.
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.
