What is CVE-2017-12581?
CVE-2017-12581 is a high-severity command injection vulnerability in n/a, published on 6 Aug 2017. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
GitHub Electron before 1.6.8 allows remote command execution because of a nodeIntegration bypass vulnerability. This also affects all applications that bundle Electron code equivalent to 1.6.8 or earlier. Bypassing the Same Origin Policy (SOP) is a precondition; however, recent Electron versions do not have strict SOP enforcement. Combining an SOP bypass with a privileged URL internally used by Electron, it was possible to execute native Node.js primitives in order to run OS commands on the user's host. Specifically, a chrome-devtools://devtools/bundled/inspector.html window could be used to eval a Node.js child_process.execFile API call.
Weakness: CWE-78
