Nilson's Blogger is prone to a local file-include vulnerability because it fails to properly sanitize user-supplied input.
An attacker can exploit this vulnerability using directory-traversal strings to include local files in the context of the webserver process. This may allow the attacker to obtain potentially sensitive information; other attacks are also possible.
This issue affects Nilson's Blogger 0.11; other versions may also be vulnerable.
