No affected components available
Affected versions of electron may be susceptible to a remote code execution flaw when certain conditions are met:
- The electron application is running on Windows.
- The electron application registers as the default handler for a protocol, such as
nodeapp://.
This vulnerability is caused by a failure to sanitize additional arguments to chromium in the command line handler for Electron.
MacOS and Linux are not vulnerable.
Recommendation
Update electron to a version that is not vulnerable. If updating is not possible, the electron team has provided the following guidance:
If for some reason you are unable to upgrade your Electron version, you can append -- as the last argument when calling app.setAsDefaultProtocolClient, which prevents Chromium from parsing further options. The double dash -- signifies the end of command options, after which only positional parameters are accepted.
app.setAsDefaultProtocolClient(protocol, process.execPath, [
'--your-switches-here',
'--'
])
The vulnerability can be exploited over the network without needing physical access. It is easy for an attacker to exploit this vulnerability. An attacker does not need any special privileges or access rights. The attacker needs the user to perform some action, like clicking a link. The impact is confined to the system where the vulnerability exists. There is a high impact on the confidentiality of the information. There is a high impact on the integrity of the data. There is a high impact on the availability of the system.
Exploitation activity has been observed. Apply available patches or mitigations urgently.
The exploit probability is critical. The vulnerability is very likely to be exploited in the next 30 days.
We did not find any exploit available. Neither in GitHub repositories nor in the Exploit-Database.
