Overview
electerm is an open-sourced terminal/ssh/telnet/serialport/sftp client
Affected versions of this package are vulnerable to Arbitrary Command Injection via the runLinux function. An attacker can execute arbitrary system commands, tamper with local files, and escalate compromise of development or runtime assets by supplying a crafted remote version string or release name that is incorporated into an exec command without validation. This is only exploitable if the attacker can control the remote release metadata served by the project's update server.
