![]() See Ĭommon.c in infosvr in ASUS WRT firmware 3.0.0.4.376_1071, 3.0.0.376.2524-g0013f52, and other versions, as used in RT-AC66U, RT-N66U, and other routers, does not properly check the MAC address for a request, which allows remote attackers to bypass authentication and execute arbitrary commands via a NET_CMD_ID_MANU_CMD packet to UDP port 9999. Several Asus router models use a service called infosvr that listens on UDP port 9999 with root privileges and contains unauthenticated command execution vulnerability. An attacker can leverage this vulnerability to execute code in the context of the device. The issue results from the lack of authentication prior to allowing alterations to the system configuration. The specific flaw exists within the control service, which listens on TCP port 9999 by default. Authentication is not required to exploit this vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of C-MORE HMI EA9 Firmware version 6.52 touch screen panels. By sending a specially-crafted packet to TCP Port 9999 with a malformed header, a remote attacker could exploit this vulnerability to cause the application to crash. The remote web management interface of Aprelium Technologies Abyss Web Server 1.1.2 and earlier does not log connection attempts to the web management port (9999), which allows remote attackers to mount brute force attacks on the administration console without detection.įirefly Media Server is vulnerable to a denial of service, caused by multiple NULL pointer dereference errors in the firefly.exe binary file.

The typical use case of the reverse proxy feature is probably when a Java application server is involved.īelow are the instructions to install Tomcat (a Java Application Server) and how to use it as a back-end with Abyss Web Server: ![]() The response to that request as received by Abyss Web Server will be forwarded to the client.Ĭlient -request-> Abyss Web Server -request-> Back-end serverĬlient <-response- Abyss Web Server <-response- Back-end server How does reverse-proxying work?Ī reverse proxy rule in Abyss Web Server establishes a mapping between a virtual path in a frontal host and another virtual path in back-end (the proxied server.)įor example, if there is a rule associating the virtual path /app on to, a request to received by Abyss Web Server will generate a request to. Reverse proxying is also the recommended way to take advantage of JSP (Java Servlet Pages), Tomcat/Jetty, node.js Web applications, or ASP.NET Core applications deployed on Kesterel. The proxied server can be another Web server or an application server with a restricted or even a trivial HTTP support that has to be shielded from external clients. ![]() Abyss Web Server can act as a reverse proxy to provide content transparently from another Web server behind it (commonly called a back-end server.)
