Cross-Site Scripting via JSONP

JSONP allows untrusted resource URLs, which provides a vector for attack by malicious actors.

angular vulnerable to regular expression denial of service via the $resource service

All versions of the package angular are vulnerable to Regular Expression Denial of Service (ReDoS) via the $resource service due to the usage of an insecure regular expression. Exploiting this vulnerability is possible by a large carefully-crafted input, which can result in catastrophic backtracking.

angular vulnerable to regular expression denial of service via the angular.copy() utility

All versions of the package angular are vulnerable to Regular Expression Denial of Service (ReDoS) via the angular.copy() utility function due to the usage of an insecure regular expression. Exploiting this vulnerability is possible by a large carefully-crafted input, which can result in catastrophic backtracking.

angular vulnerable to super-linear runtime due to backtracking

This affects versions of the package angular from 1.3.0. A regular expression used to split the value of the ng-srcset directive is vulnerable to super-linear runtime due to backtracking. With a large carefully-crafted input, this can result in catastrophic backtracking and cause a denial of service.

Note:

This package is EOL and will not receive any updates to address this issue. Users should migrate to @angular/core.

XSS via JQLite DOM manipulation functions in AngularJS

Summary

XSS may be triggered in AngularJS applications that sanitize user-controlled HTML snippets before passing them to JQLite methods like JQLite.prepend, JQLite.after, JQLite.append, JQLite.replaceWith, JQLite.append, new JQLite and angular.element.

Description

JQLite (DOM manipulation library that's part of AngularJS) manipulates input HTML before inserting it to the DOM in jqLiteBuildFragment.

One of the modifications performed expands an XHTML self-closing tag.

If jqLiteBuildFragment is called (e.g. via new JQLite(aString)) with user-controlled HTML string that was sanitized (e.g. with DOMPurify), the transformation done by JQLite may modify some forms of an inert, sanitized payload into a payload containing JavaScript - and trigger an XSS when the payload is inserted into DOM.

This is similar to a bug in jQuery htmlPrefilter function that was fixed in 3.5.0.

Proof of concept

const inertPayload = `<div><style><style/><img src=x onerror="alert(1337)"/>` 

Note that the style element is not closed and <img would be a text node inside the style if inserted into the DOM as-is. As such, some HTML sanitizers would leave the <img as is without processing it and stripping the onerror attribute.

angular.element(document).append(inertPayload);

This will alert, as <style/> will be replaced with <style></style> before adding it to the DOM, closing the style element early and reactivating img.

Patches

The issue is patched in JQLite bundled with angular 1.8.0. AngularJS users using JQuery should upgrade JQuery to 3.5.0, as a similar vulnerability affects jQuery <3.5.0.

Workarounds

Changing sanitizer configuration not to allow certain tag grouping (e.g. <option><style></option>) or inline style elements may stop certain exploitation vectors, but it's uncertain if all possible exploitation vectors would be covered. Upgrade of AngularJS to 1.8.0 is recommended.

Prototype Pollution in angular

Versions of angular prior to 1.7.9 are vulnerable to prototype pollution. The deprecated API function merge() does not restrict the modification of an Object's prototype in the , which may allow an attacker to add or modify an existing property that will exist on all objects.

Recommendation

Upgrade to version 1.7.9 or later. The function was already deprecated and upgrades are not expected to break functionality.

AngularJS allows attackers to bypass common image source restrictions

Improper sanitization of the value of the [srcset] attribute in AngularJS allows attackers to bypass common image source restrictions, which can also lead to a form of Content Spoofing https://owasp.org/www-community/attacks/Content_Spoofing .

This issue affects AngularJS versions 1.3.0-rc.4 and greater.

Note: The AngularJS project is End-of-Life and will not receive any updates to address this issue. For more information see here https://docs.angularjs.org/misc/version-support-status .

Cross site scripting in Angular

angular.js prior to 1.8.0 allows cross site scripting. The regex-based input HTML replacement may turn sanitized code into unsanitized one. Wrapping <option> elements in <select> ones changes parsing behavior, leading to possibly unsanitizing code.

AngularJS allows attackers to bypass common image source restrictions

Improper sanitization of the value of the [srcset] attribute in <source> HTML elements in AngularJS allows attackers to bypass common image source restrictions, which can also lead to a form of Content Spoofing https://owasp.org/www-community/attacks/Content_Spoofing .

This issue affects all versions of AngularJS.

Angular (deprecated package) Cross-site Scripting

All versions of package angular are vulnerable to Cross-site Scripting (XSS) due to insecure page caching in the Internet Explorer browser, which allows interpolation of <textarea> elements.

NPM package angular is deprecated. Those who want to receive security updates should use the actively maintained package @angular/core.

angular vulnerable to regular expression denial of service via the <input type="url"> element

All versions of the package angular are vulnerable to Regular Expression Denial of Service (ReDoS) via the element due to the usage of an insecure regular expression in the input[url] functionality. Exploiting this vulnerability is possible by a large carefully-crafted input, which can result in catastrophic backtracking.

AngularJS Cross-site Scripting due to failure to sanitize `xlink.href` attributes

Versions of angular prior to 1.5.0-beta.1 are vulnerable to Cross-Site Scripting. The package fails to sanitize xlink:href attributes, which may allow attackers to execute arbitrary JavaScript in a victim's browser if the value is user-controlled.

Recommendation

Upgrade to version 1.5.0-beta.1 or later.
