Browserify is a powerful tool for developers seeking to use Node.js-style modules within their browser-side JavaScript code. Versions 3.6.0 and 3.7.0, both released on December 19, 2013, offer this capability, but a closer look reveals subtle yet important distinctions. While both versions share identical core dependencies, encompassing modules like umd, url, optimist, and a suite of browser-specific shims like http-browserify and crypto-browserify, the key differentiator lies in their release timestamps. Version 3.7.0 was published roughly 33 minutes after version 3.6.0, suggesting potentially bug fixes or minor updates addressed in the later release. Developers should prioritize updating to the latest version (3.7.0 after the update) to benefit from the most recent fixes and potential performance improvements. Both releases retain the same set of development dependencies used for testing and building, including seq, tap, dnode, mkdirp, backbone, and coffee-script. The MIT license and repository on GitHub indicate a commitment to open-source collaboration and community-driven development. For developers, Browserify empowers modular JavaScript development, facilitating code organization and reusability within the browser environment, making it a crucial tool for modern web application development. Always check for the latest changes.
All the vulnerabilities related to the version 3.7.0 of the package
Regular Expression Denial of Service in uglify-js
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.
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;");
$ time node test.js 10000

sys 0m0.039s
$ time node test.js 80000
real 0m6.486s
user 0m6.229s
sys 0m0.094s
Update to version 2.6.0 or later.
Prototype Pollution in minimist
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
.
Upgrade to versions 0.2.1, 1.2.3 or later.
Prototype Pollution in minimist
Minimist prior to 1.2.6 and 0.2.4 is vulnerable to Prototype Pollution via file index.js
, function setKey()
(lines 69-95).
Potential Command Injection in shell-quote
Affected versions of shell-quote
do not properly escape command line arguments, which may result in command injection if the library is used to escape user input destined for use as command line arguments.
The following characters are not escaped properly: >
,;
,{
,}
Bash has a neat but not well known feature known as "Bash Brace Expansion", wherein a sub-command can be executed without spaces by running it between a set of {}
and using the ,
instead of
to seperate arguments. Because of this, full command injection is possible even though it was initially thought to be impossible.
const quote = require('shell-quote').quote;
console.log(quote(['a;{echo,test,123,234}']));
// Actual "a;{echo,test,123,234}"
// Expected "a\;\{echo,test,123,234\}"
// Functional Equivalent "a; echo 'test' '123' '1234'"
Update to version 1.6.1 or later.
Potential for Script Injection in syntax-error
Versions of syntax-error
prior to 1.1.1 are affected by a cross-site scripting vulnerability which may allow a malicious file to execute code when browserified.
Update to version 1.1.1 or later.
