EasyITSP - 'voicemail.php' Directory Traversal
source: https://www.securityfocus.com/bid/57741/info
EasyITSP 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 access arbitrary files in the context of the application. This may aid in further attacks.
EasyITSP 2.0.7 and prior versions are vulnerable.
