The component accepts XML input through the publisher without disabling external entity resolution. This allows malicious actors to submit a crafted XML payload that exploits the unescaped external entity references.
By leveraging this vulnerability, a malicious actor can read confidential files from the product's file system or access limited HTTP resources reachable via HTTP GET requests to the vulnerable product.
The authentication endpoint fails to adequately validate user-supplied input before reflecting it back in the response. This allows an attacker to inject malicious script payloads into the input parameters, which are then executed by the victim's browser.
Successful exploitation can enable an attacker to redirect the user's browser to a malicious website, modify the UI of the web page, or retrieve information from the browser. However, the impact is limited as session-related sensitive cookies are protected by the httpOnly flag, preventing session hijacking.
A reflected cross-site scripting (XSS) vulnerability in /authenticationendpoint/login.do of WSO2 API Manager before 4.2.0 allows attackers to execute arbitrary web scripts or HTML via a crafted payload injected into the tenantDomain parameter.
