A Reflected Cross-Site Scripting (XSS) vulnerability (CVE-2022-29548) has been discovered in the Management Console of several WSO2 products, allowing an attacker to inject malicious code that can be executed by unsuspecting users. Affected versions of the software include API Manager, API Manager Analytics, API Microgateway, Data Analytics Server, Enterprise Integrator, IS as Key Manager, Identity Server, Identity Server Analytics, and WSO2 Micro Integrator.

Exploit Details

The reflected XSS vulnerability occurs when user input is accepted without proper validation and subsequently used in the Management Console. This allows an attacker to craft a URL with malicious scripts that get executed when a user visits the URL. The malicious scripts can steal sensitive information, perform unauthorized actions, or redirect the user to other malicious sites.

Here's a simple example of a malicious URL that demonstrates the vulnerability

https://example.com/wso2/management_console?username=<script>alert('XSS');</script>;

When a user visits this URL, the malicious script injected into the "username" parameter will be executed, displaying an alert with the text "XSS."
