Descriptions

The Easy Newsletter Signups WordPress plugin through 1.0.4 does not properly sanitise and escape a parameter before using it in a SQL statement, leading to a SQL injection exploitable by high privilege users such as admin

El complemento Easy Newsletter Signups de WordPress hasta la versión 1.0.4 no sanitiza ni escapa adecuadamente un parámetro antes de usarlo en una declaración SQL, lo que genera una inyección de SQL explotable por usuarios con privilegios elevados, como el administrador.

The Easy Newsletter Signups plugin for WordPress is vulnerable to SQL Injection via the 'nsl_id' parameter in all versions up to, and including, 1.0.4 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers, with administrator-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.
