Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')

CVE-2025-5770

Medium
6.1/10

Summary

A Reflected Cross-Site Scripting (XSS) vulnerability exists in the authentication endpoints of multiple WSO2 products due to a lack of output encoding. A malicious actor can inject arbitrary JavaScript payloads into the authentication endpoint, which are reflected back in the response, enabling browser-based attacks. Exploitation may result in redirection to malicious websites, UI manipulation, or unauthorized data access from the victims browser. However, session-related cookies are protected with the "httpOnly" flag, which mitigates session hijacking via this vector. The package "org.wso2.identity.apps:authentication-portal" is affected through version 2.25.13.

CWE-79 - Cross Site Scripting

Cross-Site Scripting, commonly referred to as XSS, is the most dominant class of vulnerabilities. It allows an attacker to inject malicious code into a pregnable web application and victimize its users. The exploitation of such a weakness can cause severe issues such as account takeover, and sensitive data exfiltration. Because of the prevalence of XSS vulnerabilities and their high rate of exploitation, it has remained in the OWASP top 10 vulnerabilities for years.
