Loading vulnerability…
A vulnerability in Internet Explorer 5.5 and earlier allows a web site to supply command-line arguments when invoking a Telnet session from the browser. When the client system is configured to use the Telnet client included with Services for Unix (SFU) 2.0, those attacker-controlled arguments are passed to the external Telnet program without proper neutralization of argument delimiters. This is an argument injection flaw in the browser-to-handler invocation path that can cause the Telnet client to execute with unintended options and, in the affected configuration, may result in arbitrary command execution.
