Descriptions

systeminformation is an open source system and OS information library for node.js. A command injection vulnerability has been discovered in versions of systeminformation prior to 5.6.4. The issue has been fixed with a parameter check on user input. Please upgrade to version >= 5.6.4. If you cannot upgrade, be sure to check or sanitize service parameters that are passed to si.inetLatency(), si.inetChecksite(), si.services(), si.processLoad() and other commands. Only allow strings, reject any arrays. String sanitation works as expected.

systemminformation es un sistema de código abierto y una biblioteca de información de SO para node.js. Se ha detectado una vulnerabilidad de inyección de comandos en systeminformation versiones de anteriores a 5.6.4. El problema ha sido corregido con una comprobación de parámetros en la entrada del usuario. Por favor actualice a las versiones posteriores a 5.6.4 e incluyéndola. Si no puede actualizar, asegúrese de comprobar o sanear los parámetros de servicio que son pasados a si.inetLatency (), si.inetChecksite(), si.services(), si.processLoad() y otros comandos. Solo permita cadenas, rechace cualquier arreglo. El saneamiento de cuerdas funciona como se esperaba
