Multiple SQL injection vulnerabilities in Dolibarr ERP/CRM 3.5.3 allow remote authenticated users to execute arbitrary SQL commands via the (1) entity parameter in an update action to user/fiche.php or (2) sortorder parameter to user/group/index.php.
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.
