      "value": "A privilege escalation vulnerability in Wowza Streaming Engine 4.8.0 and earlier allows any unprivileged Linux user to escalate privileges to root. The installer sets too relaxed permissions on /usr/local/WowzaStreamingEngine/bin/* core program files. By injecting a payload into one of those files, it will run with the same privileges as the Wowza server, root. For example, /usr/local/WowzaStreamingEngine/bin/tune.sh could be replaced with a Trojan horse. This issue was resolved in Wowza Streaming Engine 4.8.5."

      "value": "Una vulnerabilidad de escalada de privilegios en Wowza Streaming Engine versiones 4.8.0 y anteriores permite a cualquier usuario de Linux no privilegiado escalar privilegios a root. El instalador establece permisos demasiado flexibles sobre los archivos de programa principales /usr/local/WowzaStreamingEngine/bin/*. Mediante la inyecci\u00f3n de una carga \u00fatil en uno de esos archivos, se ejecutar\u00e1 con los mismos privilegios que el servidor Wowza, root. Por ejemplo, el archivo /usr/local/WowzaStreamingEngine/bin/tune.sh podr\u00eda ser reemplazado por uno de tipo caballo de Troya. Este problema se resolvi\u00f3 en Wowza Streaming Engine 4.8.5"
