Description
Konsole supports loading URLs from the scheme handlers such as telnet://URL. This can be executed regardless of whether the telnet binary is available.
In this mode konsole had a path where if telnet was not available it would fall back to using bash for the given arguments provided; which is the URL provided. This allows an attacker to execute arbitrary code.
Browsers typically provide a prompt when a user opens an external scheme handler which would look suspicious, requiring user interaction
to be exploitable.
