Multiple SQL injection vulnerabilities in u5CMS before 3.9.4 allow remote attackers to execute arbitrary SQL commands via the name parameter to (1) copy2.php, (2) localize.php, (3) metai.php, (4) nc.php, (5) new2.php, or (6) rename2.php in u5admin/; (7) c parameter to u5admin/editor.php; (8) typ parameter to u5admin/meta2.php; or (9) newname parameter to u5admin/rename2.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.
