Mautic Cross-site Scripting

A cross-site scripting (XSS) vulnerability in the web tracking component of Mautic before 4.3.0 allows remote attackers to inject executable javascript (2022-06-20, CVE-2022-25772)

A cross-site scripting (XSS) vulnerability in the installer component of Mautic before 4.3.0 allows admins to inject executable javascript (2022-06-01, CVE-2021-27914)

For Mautic versions prior to 3.3.4/4.0.0, there is an XSS vulnerability on Mautic's password reset page where a vulnerable parameter, "bundle," in the URL could allow an attacker to execute Javascript code. The attacker would be required to convince or trick the target into clicking a password reset URL with the vulnerable parameter utilized. (2021-08-30, CVE-2021-27909)

Insufficient sanitization / filtering allows for arbitrary JavaScript Injection in Mautic using the bounce management callback function. The values submitted in the "error" and "error_related_to" parameters of the POST request of the bounce management callback will be permanently stored and executed once the details page of an affected lead is opened by a Mautic user. An attacker with access to the bounce management callback function (identified with the Mailjet webhook, but it is assumed this will work uniformly across all kinds of webhooks) can inject arbitrary JavaScript Code into the "error" and "error_related_to" parameters of the POST request (POST /mailer//callback). It is noted that there is no authentication needed to access this function. The JavaScript Code is stored permanently in the web application and executed every time an authenticated user views the details page of a single contact / lead in Mautic. This means, arbitrary code can be executed to, e.g., steal or tamper with information. (2021-08-30, CVE-2021-27910)

Mautic versions before 3.3.4/4.0.0 are vulnerable to an inline JS XSS attack through the contact's first or last name and triggered when viewing a contact's details page then clicking on the action drop down and hovering over the Campaigns button. Contact first and last name can be populated from different sources such as UI, API, 3rd party syncing, forms, etc. (2021-08-30, CVE-2021-27911)

Mautic versions before 3.3.4/4.0.0 are vulnerable to an inline JS XSS attack when viewing Mautic assets by utilizing inline JS in the title and adding a broken image URL as a remote asset. This can only be leveraged by an authenticated user with permission to create or edit assets. (2021-08-30, CVE-2021-27912)

A cross-site scripting (XSS) vulnerability in the forms component of Mautic before 3.2.4 allows remote attackers to inject executable JavaScript via mautic[return] (a different attack method than CVE-2020-35124, but also related to the Referer concept). (2021-02-09, CVE-2020-35125)

A cross-site scripting (XSS) vulnerability in the assets component of Mautic before 3.2.4 allows remote attackers to inject executable JavaScript through the Referer header of asset downloads. (2021-01-28, CVE-2020-35124)

Mautic before 3.2.4 is affected by stored XSS. An attacker with access to Social Monitoring, an application feature, could attack other users, including administrators. For example, an attacker could load an externally drafted JavaScript file that would allow them to eventually perform actions on the target user’s behalf, including changing the user’s password or email address or changing the attacker’s user role from a low-privileged user to an administrator account. (2021-01-19, CVE-2020-35129)

Mautic before 3.2.4 is affected by stored XSS. An attacker with permission to manage companies, an application feature, could attack other users, including administrators. For example, by loading an externally crafted JavaScript file, an attacker could eventually perform actions as the target user. These actions include changing the user passwords, altering user or email addresses, or adding a new administrator to the system. (2021-01-19, CVE-2020-35128)

An issue was discovered in Mautic 2.13.1. It has Stored XSS via the company name field. (2019-09-20, CVE-2018-11200)

An issue was discovered in Mautic 2.13.1. There is Stored XSS via the authorUrl field in config.json. (2019-09-06, CVE-2018-11198)

Mautic before v2.13.0 has stored XSS via a theme config file. (2018-04-18, CVE-2018-8071)

Cross site scripting is an attack where a web page executes code that is injected by an adversary. It usually appears, when users input is presented. This attack can be used to impersonate a user, take over control of the session, or even steal API keys.

The attack can be executed e.g. when you application injects the request parameter directly into the HTML code of the page returned to the user:

https://server.com/confirmation?message=Transaction+Complete

what results in:

<span>Confirmation: Transaction Complete</span>

In that case the message can be modified to become a valid Javascript code, e.g.:

https://server.com/confirmation?message=<script>dangerous javascript code here</script>

and it will be executed locally by the user's browser with full access to the user's personal application/browser data:

<span>Confirmation: <script>dangerous javascript code here</script></span>
