Detailed vulnerability description
The vulnerability allows a remote user to redirect victims to arbitrary URL.
The vulnerability exists due to improper sanitization of user-supplied data. A remote low-privileged user that does not hold the “admin” or “power” Splunk roles could create a views dashboard with a custom background using the data:image/png;base64 protocol that could potentially lead to an unvalidated redirect.
Successful exploitation of this vulnerability may allow a remote attacker to perform a phishing attack and steal potentially sensitive information.
