Wso2: >> Traffic Manager >> 4.6.0 Security Vulnerabilities
The throttling event handling mechanism in multiple WSO2 products accepts user-supplied JSON payloads without sufficient validation of their structure and content. This allows an unauthenticated remote attacker to inject malicious JSON data that can lead to a persistent denial of service condition.
Successful exploitation of this vulnerability can disrupt the API Gateway, preventing legitimate API traffic from being processed and impacting complete service availability. The denial of service is persistent, requiring manual intervention to restore normal operations.

The software accepts user-supplied input via a URL parameter without adequate output encoding before reflecting it back to the user's browser. This condition allows an attacker to inject malicious script content into pages served by the application.
By leveraging this weakness, an attacker can cause the user's browser to redirect to a malicious website, modify the UI of the webpage, or retrieve information from the browser. However, the impact is mitigated by the use of httpOnly flags on session-related cookies, preventing session hijacking.

A malicious actor with administrative privileges can upload an arbitrary file to a user-controlled location within the deployment via a system REST API. Successful uploads may lead to remote code execution.
By leveraging the vulnerability, a malicious actor may perform Remote Code Execution by uploading a specially crafted payload.

A Cross-Site Request Forgery (CSRF) vulnerability exists in multiple WSO2 products due to the use of the HTTP GET method for state-changing operations within admin services, specifically in the event processor of the Carbon console. Although the SameSite=Lax cookie attribute is used as a mitigation, it is ineffective in this context because it allows cookies to be sent with cross-origin top-level navigations using GET requests.
A malicious actor can exploit this vulnerability by tricking an authenticated user into visiting a crafted link, leading the browser to issue unintended state-changing requests. Successful exploitation could result in unauthorized operations such as data modification, account changes, or other administrative actions. According to WSO2 Secure Production Guidelines, exposure of Carbon console services to untrusted networks is discouraged, which may reduce the impact in properly secured deployments.
