SECURITY ADVISORY WSO2-2023-2831

Published: May 31, 2024

Version: 1.0.0

Severity: Medium

CVSS Score: 6.1 (CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N)

---

AFFECTED PRODUCTS

• WSO2 API Manager : 3.2.0

OVERVIEW

A reflected cross site scripting vulnerability has been identified in API Document.

DESCRIPTION

Due to lack of output encoding, a reflected Cross Site Scripting (XSS) attack can be carried out by injecting a malicious payload into API Documents.

IMPACT

By leveraging the XSS attack, a malicious actor can make the browser get redirected to a malicious website, make changes in the UI of the web page, retrieve information from the browser or harm otherwise. However, since all the session related sensitive cookies are set with httpOnly flag and protected, session hijacking or similar attacks would not be possible.

SOLUTION

We highly recommend to migrate the latest version of WSO2 API Manager to mitigate the identified vulnerabilities.
