Summary
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.

"value": "Se detect\u00f3 un problema en LibreNMS versi\u00f3n 1.50.1. Los scripts que manejan las opciones de graficaci\u00f3n (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 par\u00e1metros son filtrados con la funci\u00f3n mysqli_real_escape_string, que son solo \u00fatil para impedir ataques de inyecci\u00f3n SQL; Otros par\u00e1metros 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 vers\u00e1til y un atacante podr\u00eda aprovechar esto para realizar una serie de ataques, incluyendo la divulgaci\u00f3n de la estructura del directorio y los nombres de los archivos, la divulgaci\u00f3n del contenido de archivos, la denegaci\u00f3n de servicio o la escritura de archivos arbitrarios. NOTA: relativo al CVE-2019-10665, esto requiere autenticaci\u00f3n y la diferenciaci\u00f3n de los nombres de ruta (path)."
