Multiple SQL injection vulnerabilities in OrangeHRM 2.7.1 RC 1 allow remote authenticated administrators to execute arbitrary SQL commands via the sortField parameter to (1) viewCustomers, (2) viewPayGrades, or (3) viewSystemUsers in symfony/web/index.php/admin/, as demonstrated using cross-site request forgery (CSRF) attacks.
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.
