CVE-2024-4867
Cross-Site Scripting via Developer Portal in WSO2 API Manager Enables UI Modification and Information Retrieval
CVSS Score
5.4
EPSS Score
0.0%
EPSS Percentile
0th
The WSO2 API Manager developer portal accepts user-supplied input without enforcing expected validation constraints or proper output encoding. This deficiency allows a malicious actor to inject script content that is executed within the context of a user's browser. By leveraging this cross-site scripting vulnerability, a malicious actor can cause the browser to redirect to a malicious website, make changes to the UI of the web page, or retrieve information from the browser. However, session hijacking is not possible as all session-related sensitive cookies are protected by the httpOnly flag.
