VAR-200203-0082

Vulnerability from variot - Updated: 2025-04-03 22:30

Telnet proxy in Avirt Gateway Suite 4.2 does not require authentication for connecting to the proxy system itself, which allows remote attackers to list file contents of the proxy and execute arbitrary commands via a "dos" command. Avirt Gateway Suite is a product combining the functionality of Avirt Gateway and Avirt Mail. It is designed as a single solution for collection of client machines sharing a single internet connection. It is available for the Microsoft Windows operating system. By default, a telnet proxy server accepts connections from a configured, accepted IP address range. Any user may connect and browse the server file system or gain access to a command prompt. By default, the server runs with SYSTEM privileges. The software package contains a telnet proxy program, which listens to port 23 by default

Drag nodes to arrange them. Double-click a related vulnerability to open it, or a source to visit its link. The Physics button on the left tunes the layout and the simulation; the legend at the bottom left hides or shows nodes by kind and by sighting type.

Forecast uses a logistic model when the trend is rising, or an exponential decay model when the trend is falling. Fitted via linearized least squares.
