Description

BlindBlog is prone to a local file-include vulnerability and multiple SQL-injection vulnerabilities because it fails to properly sanitize user-supplied input.

An attacker can exploit the local file-include vulnerability using directory-traversal strings to view and execute arbitrary local files within the context of the webserver process. Information harvested may aid in further attacks.

The attacker can exploit the SQL-injection vulnerabilities to compromise the application, access or modify data, or exploit latent vulnerabilities in the underlying database.

BlindBlog 1.3.1 is vulnerable, other versions may also be affected.
