b. SSRF and CRLF injection issues in vSphere Web client

The Flash-based vSphere Web Client (i.e. not the new HTML5-based vSphere Client) contains server side request forgery (SSRF) and CRLF injection issues due to improper neutralization of URLs. An attacker may exploit these issues by sending a POST request with modified headers towards internal services leading to information disclosure.
