✍️ Description

External Control of File Name or Path is a type of security flaw in which users can access resources from restricted locations on a file system. It is commonly called path traversal. If an attacker performs a path traversal attack successfully, they could potentially view sensitive files or other confidential information. This threat is possible when applications allow a user to specify the filename used in a file system operation.

The user input POST parameter v_package of index.php is unsanitized resulting external control of filename.
