Description

An issue was discovered in SDCMS V1.7. In the \app\admin\controller\themecontroller.php file, the check_bad() function's filtering is not strict, resulting in PHP code execution. This occurs because some dangerous PHP functions (such as "eval") are blocked but others (such as "system") are not, and because ".php" is blocked but ".PHP" is not blocked.

• CWE-94Improper Control of Generation of Code ('Code Injection')The product constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment.
