Descriptions

An issue was discovered in LibreNMS 1.50.1. The scripts that handle graphing options (includes/html/graphs/common.inc.php and includes/html/graphs/graphs.inc.php) do not sufficiently validate or encode several fields of user supplied input. Some parameters are filtered with mysqli_real_escape_string, which is only useful for preventing SQL injection attacks; other parameters are unfiltered. This allows an attacker to inject RRDtool syntax with newline characters via the html/graph.php and html/graph-realtime.php scripts. RRDtool syntax is quite versatile and an attacker could leverage this to perform a number of attacks, including disclosing directory structure and filenames, disclosing file content, denial of service, or writing arbitrary files. NOTE: relative to CVE-2019-10665, this requires authentication and the pathnames differ.

Se detectó un problema en LibreNMS versión 1.50.1. Los scripts que manejan las opciones de graficación (archivos includes/html/graphs/common.inc.php e includes/html/graphs/graphs.inc.php) no comprueban ni codifican suficientemente varios campos de entrada suministrada por usuario. Algunos parámetros son filtrados con la función mysqli_real_escape_string, que son solo útil para impedir ataques de inyección SQL; Otros parámetros no son filtrados. Esto permite a un atacante inyectar la sintaxis RRDtool con caracteres newline por medio de los scripts html/graph.php y html/graph-realtime.php. La sintaxis de RRDtool es sumamente versátil y un atacante podría aprovechar esto para realizar una serie de ataques, incluyendo la divulgación de la estructura del directorio y los nombres de los archivos, la divulgación del contenido de archivos, la denegación de servicio o la escritura de archivos arbitrarios. NOTA: relativo al CVE-2019-10665, esto requiere autenticación y la diferenciación de los nombres de ruta (path).
