(2022-04-21, CVE-2022-29548)

In accountrecoveryendpoint/recoverpassword.do in WSO2 Identity Server 5.7.0, it is possible to perform a DOM-Based XSS attack affecting the callback parameter modifying the URL that precedes the callback parameter. Once the username or password reset procedure is completed, the JavaScript code will be executed. (recoverpassword.do also has an open redirect issue for a similar reason.) (2021-12-07, CVE-2021-36760)

WSO2 Management Console through 5.10 allows XSS via the carbon/admin/login.jsp msgId parameter. (2021-04-05, CVE-2020-17453)

Cross-Site Scripting (XSS) vulnerability on WSO2 API Manager 3.1.0. By exploiting a Cross-site scripting vulnerability the attacker can hijack a logged-in user’s session by stealing cookies which means that a malicious hacker can change the logged-in user’s password and invalidate the session of the victim while the hacker maintains access. (2020-10-29, CVE-2020-27885)

WSO2 API Manager 3.1.0 and earlier has reflected XSS on the "publisher" component's admin interface. More precisely, it is possible to inject an XSS payload into the owner POST parameter, which does not filter user inputs. By putting an XSS payload in place of a valid Owner Name, a modal box appears that writes an error message concatenated to the injected payload (without any form of data encoding). This can also be exploited via CSRF. (2020-10-21, CVE-2020-17454)

An issue was discovered in certain WSO2 products. The Try It tool allows Reflected XSS. This affects API Manager 2.2.0, API Manager Analytics 2.2.0, API Microgateway 2.2.0, Data Analytics Server 3.2.0, Enterprise Integrator through 6.6.0, IS as Key Manager 5.5.0, Identity Server 5.5.0 and 5.8.0, Identity Server Analytics 5.5.0, and IoT Server 3.3.0 and 3.3.1.

An issue was discovered in certain WSO2 products. The Try It tool allows Reflected XSS. This affects API Manager through 3.1.0, API Manager Analytics 2.5.0, IS as Key Manager through 5.10.0, Identity Server through 5.10.0, Identity Server Analytics through 5.6.0, and IoT Server 3.1.0. (2020-08-27, CVE-2020-24706)

An issue was discovered in WSO2 API Manager 2.6.0, WSO2 IS as Key Manager 5.7.0, and WSO2 Identity Server 5.8.0. If there is a claim dialect configured with an XSS payload in the dialect URI, and a user picks up this dialect's URI and adds it as the service provider claim dialect while configuring the service provider, that payload gets executed. The attacker also needs to have privileges to log in to the management console, and to add and configure claim dialects. (2020-01-28, CVE-2019-20436)

An issue was discovered in WSO2 API Manager 2.6.0, WSO2 IS as Key Manager 5.7.0, and WSO2 Identity Server 5.8.0. When a custom claim dialect with an XSS payload is configured in the identity provider basic claim configuration, that payload gets executed, if a user picks up that dialect's URI as the provisioning claim in the advanced claim configuration of the same Identity Provider. The attacker also needs to have privileges to log in to the management console, and to add and update identity provider configurations. (2020-01-28, CVE-2019-20437)

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>
