Omnissa UAG contains a Cross-Origin Resource Sharing (CORS) bypass vulnerability. A malicious actor with network access to UAG may be able to bypass administrator-configured CORS restrictions to gain access to sensitive networks.
The product uses a web-client protection mechanism such as a Content Security Policy (CSP) or cross-domain policy file, but the policy includes untrusted domains with which the web client is allowed to communicate.

If a cross-domain policy file includes domains that should not be trusted, such as when using wildcards under a high-level domain, then the application could be attacked by these untrusted domains. In many cases, the attack can be launched without the victim even being aware of it.
