Description Marian Rehak 2020-08-26 09:35:20 UTC
In Nim 1.2.4, the standard library browsers mishandles the URL argument to browsers.openDefaultBrowser. This argument can be a local file path that will be opened in the default explorer. An attacker can pass one argument to the underlying open command to execute arbitrary registered system commands.
