What it is

electerm is an open-sourced terminal/ssh/sftp/telnet/serialport/RDP/VNC/Spice/ftp client. From versions 3.0.6 to before 3.8.15, electerm is vulnerable to arbitrary local code execution via deep links, CLI --opts, or crafted shortcuts. Exploit requires clicking a crafted electerm://... link or opening a crafted shortcut/command that launches electerm with attacker-controlled opts. This issue has been patched in version 3.8.15.
