CVE-2018-1000006

Remote Code Execution in electron

Public exploit code

Working exploit or proof of concept code has been published for this vulnerability. Treat unpatched systems as at risk.

Impact

Affected versions of `electron` may be susceptible to a remote code execution flaw when certain conditions are met: 1. The electron application is running on Windows. 2. 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', '--' ]) ```
