Wowza Streaming Engine 4.5.0 contains multiple reflected cross-site scripting vulnerabilities in the enginemanager interface where input passed through various parameters is not properly sanitized before being returned to users. Attackers can inject malicious script code through parameters like appName, vhost, uiAppType, and wowzaCloudDestinationType in multiple endpoints to execute arbitrary HTML and JavaScript in a user's browser session.

Wowza Streaming Engine 4.5.0 contains a cross-site request forgery vulnerability that allows attackers to perform administrative actions by crafting malicious web pages. Attackers can trick logged-in administrators into visiting a malicious site that submits POST requests to the user edit endpoint to create new admin accounts with arbitrary credentials.

Wowza Streaming Engine 4.5.0 contains a privilege escalation vulnerability that allows authenticated read-only users to elevate privileges to administrator by manipulating POST parameters. Attackers can send POST requests to the user edit endpoint with accessLevel set to 'admin' and advUser parameters set to 'true' and 'on' to gain administrative access.

Wowza Streaming Engine 4.5.0 contains a local privilege escalation vulnerability that allows authenticated users to escalate privileges by replacing executable files due to improper file permissions granting full access to the Everyone group.
