CWE-1321
AllowedImproperly Controlled Modification of Object Prototype Attributes ('Prototype Pollution')
Abstraction: Variant · Status: Incomplete
The product receives input from an upstream component that specifies attributes that are to be initialized or updated in an object, but it does not properly control modifications of attributes of the object prototype.
781 vulnerabilities reference this CWE, most recent first.
GHSA-82JV-9WJW-PQH6
Vulnerability from github – Published: 2024-04-17 22:26 – Updated: 2024-04-17 22:26Summary
A prototype pollution in derby can crash the application, if the application author has atypical HTML templates that feed user input into an object key.
Attribute keys are almost always developer-controlled, not end-user-controlled, so this shouldn't be an issue in practice for most applications.
Details
emit(context: Context, target: T) {
const node = traverseAndCreate(context.controller, this.segments);
node[this.lastSegment] = target;
this.addListeners(target, node, this.lastSegment);
}
The emit() function in src/templates/templates.ts is called without sanitizing the variable this.lastSegment. The variable this.lastSegment can be set to __proto__, and this will pollute the prototype of Javascipt Object (node['__proto__'] = target).
PoC
To reproduce this vulnerability, you can adjust the test case ignores DOM mutations in components\' create() in test/dom/ComponentHarness.mocha.js.
it('ignores DOM mutations in components\' create()', function() {
function Box() {}
Box.view = {
is: 'box',
- source: '<index:><div class="box" as="boxElement"></div>'
+ source: '<index:><div class="box" as="__proto__"></div>'
};
Box.prototype.create = function() {
this.boxElement.className = 'box-changed-in-create';
};
var harness = runner.createHarness('<view is="box" />', Box);
expect(harness).to.render('<div class="box"></div>');
});
When as attribute is controlled by attackers, the variable in this.lastSegment will exactly take value__proto__ and prototype pollution happens.
Patch
Add a check on this.lastSegment can prevent this attack.
emit(context: Context, target: T) {
const node = traverseAndCreate(context.controller, this.segments);
+ if (this.lastSegment.includes('__proto__') || this.lastSegment.includes('prototype')) {
+ throw new Error('Unsafe code detected');
+ }
node[this.lastSegment] = target;
this.addListeners(target, node, this.lastSegment);

GHSA-87QP-7CW8-8Q9C
Vulnerability from github – Published: 2024-03-25 06:30 – Updated: 2024-03-27 21:57Duplicate Advisory
This advisory has been withdrawn because it is a duplicate of GHSA-2g4c-8fpm-c46v. This link is maintained to preserve external references.
Original Description
Versions of the package web3-utils before 4.2.1 are vulnerable to Prototype Pollution via the utility functions format and mergeDeep, due to insecure recursive merge. An attacker can manipulate an object's prototype, potentially leading to the alteration of the behavior of all objects inheriting from the affected prototype by passing specially crafted input to these functions.

Mitigation
By freezing the object prototype first (for example, Object.freeze(Object.prototype)), modification of the prototype becomes impossible.
Mitigation
By blocking modifications of attributes that resolve to object prototype, such as proto or prototype, this weakness can be mitigated.
Mitigation
Strategy: Input Validation
When handling untrusted objects, validating using a schema can be used.
Mitigation
By using an object without prototypes (via Object.create(null) ), adding object prototype attributes by accessing the prototype via the special attributes becomes impossible, mitigating this weakness.
Mitigation
Map can be used instead of objects in most cases. If Map methods are used instead of object attributes, it is not possible to access the object prototype or modify it.
CAPEC-1: Accessing Functionality Not Properly Constrained by ACLs
In applications, particularly web applications, access to functionality is mitigated by an authorization framework. This framework maps Access Control Lists (ACLs) to elements of the application's functionality; particularly URL's for web apps. In the case that the administrator failed to specify an ACL for a particular element, an attacker may be able to access it with impunity. An attacker with the ability to access functionality not properly constrained by ACLs can obtain sensitive information and possibly compromise the entire application. Such an attacker can access resources that must be available only to users at a higher privilege level, can access management sections of the application, or can run queries for data that they otherwise not supposed to.
CAPEC-180: Exploiting Incorrectly Configured Access Control Security Levels
An attacker exploits a weakness in the configuration of access controls and is able to bypass the intended protection that these measures guard against and thereby obtain unauthorized access to the system or network. Sensitive functionality should always be protected with access controls. However configuring all but the most trivial access control systems can be very complicated and there are many opportunities for mistakes. If an attacker can learn of incorrectly configured access security settings, they may be able to exploit this in an attack.
CAPEC-77: Manipulating User-Controlled Variables
This attack targets user controlled variables (DEBUG=1, PHP Globals, and So Forth). An adversary can override variables leveraging user-supplied, untrusted query variables directly used on the application server without any data sanitization. In extreme cases, the adversary can change variables controlling the business logic of the application. For instance, in languages like PHP, a number of poorly set default configurations may allow the user to override variables.
