Description
A reflected cross-site scripting (XSS) vulnerability exists in multiple WSO2 products due to insufficient output encoding in error messages generated by the JDBC user store connection validation request. A malicious actor can inject a specially crafted payload into the request, causing the browser to execute arbitrary JavaScript in the context of the vulnerable page. This vulnerability may allow UI manipulation, redirection to malicious websites, or data exfiltration from the browser. However, since all session-related sensitive cookies are protected with the httpOnly flag, session hijacking is not possible.
Affected products
wso2: api manager; wso2: enterprise integrator; wso2: identity server; wso2: identity server as key manager; wso2: open banking am; wso2: open banking iam
