Summary
electerm: Command Injection in File System Operations (rmrf, mv, cp)
Details

electerm is an open-sourced terminal/ssh/sftp/telnet/serialport/RDP/VNC/Spice/ftp client. Prior to 3.11.11, electerm constructs operating system commands in src/app/lib/fs.js by interpolating untrusted file paths into the rmrf(), mv(), and cp() functions. A malicious SSH or SFTP server can provide a filename containing quote characters and shell metacharacters, and a victim can cause that filename to reach the affected operation during remote-to-local transfer, conflict renaming, copying, moving, or removal. The generated rm -rf, mv, cp -r, PowerShell Remove-Item, Move-Item, or Copy-Item command can then interpret the filename as shell syntax. This allows arbitrary command execution with the electerm desktop user's privileges on POSIX and Windows systems, enabling data exfiltration, file modification, malware installation, or denial of service. This issue is fixed in version 3.11.11.
