XML External Entity Processing Enables Remote Local File Disclosure in Wowza Streaming Engine

Wowza Streaming Engine before 4.12.2 processes XML external entities, which allows remote attackers to read local files with the privileges of the Wowza Streaming Engine process.

Wowza Streaming Engine 4.5.0 Local Privilege Escalation via nssm_x64.exe

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. Attackers can replace the nssm_x64.exe binary in the manager and engine service directories with malicious executables to execute code with LocalSystem privileges when services restart.

Wowza Streaming Engine 4.5.0 Privilege Escalation via user edit

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 CSRF via user edit endpoint

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 Multiple Cross-Site Scripting Vulnerabilities

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.

Application Delete Path Traversal in Wowza Streaming Engine

Path Traversal in the Manager component of Wowza Streaming Engine below 4.9.1 allows an administrator user to delete any directory on the file system if the target directory contains an XML definition file.

Application Creation Path Traversal in Wowza Streaming Engine

Path Traversal in the Manager component of Wowza Streaming Engine below 4.9.1 allows an administrator user to create an XML definition file anywhere on the file system.

Application Copy Path Traversal in Wowza Streaming Engine

Path Traversal in the Manager component of Wowza Streaming Engine below 4.9.1 allows an administrator user to read any file on the file system if the target directory contains an XML definition file.

Stream Target Remote Code Execution in Wowza Streaming Engine

Wowza Streaming Engine below 4.9.1 permits an authenticated Streaming Engine Manager administrator to define a custom application property and poison a stream target for high-privilege remote code execution.

Stored Cross-Site Scripting in Wowza Streaming Engine

Stored Cross-Site Scripting in the Manager component of Wowza Streaming Engine below 4.9.1 allows an unauthenticated attacker to inject client-side JavaScript into the web dashboard to automatically hijack admin accounts.

Wowza Streaming Engine through 4.8.11+5 could allow an authenticated, remote attacker to exhaust filesystem resources via the /enginemanager/server/vhost/historical.jsdata vhost parameter. This is due to the insufficient management of available filesystem resources. An attacker could exploit this vulnerability through the Virtual Host Monitoring section by requesting random virtual-host historical data and exhausting available filesystem resources. A successful exploit could allow the attacker to cause database errors and cause the device to become unresponsive to web-based management. (Manual intervention is required to free filesystem resources and return the application to an operational state.)

A Cross-Site Request Forgery (CSRF) vulnerability in Wowza Streaming Engine through 4.8.11+5 allows a remote attacker to delete a user account via the /enginemanager/server/user/delete.htm userName parameter. The application does not implement a CSRF token for the GET request. This issue was resolved in Wowza Streaming Engine release 4.8.14.

Wowza Streaming Engine through 4.8.5 (in a default installation) has incorrect file permissions of configuration files in the conf/ directory. A regular local user is able to read and write to all the configuration files, e.g., modify the application server configuration.

Wowza Streaming Engine before 4.8.8.01 (in a default installation) has cleartext passwords stored in the conf/admin.password file. A regular local user is able to read usernames and passwords.

A remote authenticated authorization-bypass vulnerability in Wowza Streaming Engine 4.8.0 and earlier allows any read-only user to issue requests to the administration panel in order to change functionality. For example, a read-only user may activate the Java JMX port in unauthenticated mode and execute OS commands under root privileges. This issue was resolved in Wowza Streaming Engine 4.8.5.

A privilege escalation vulnerability in Wowza Streaming Engine 4.8.0 and earlier allows any unprivileged Linux user to escalate privileges to root. The installer sets too relaxed permissions on /usr/local/WowzaStreamingEngine/bin/* core program files. By injecting a payload into one of those files, it will run with the same privileges as the Wowza server, root. For example, /usr/local/WowzaStreamingEngine/bin/tune.sh could be replaced with a Trojan horse. This issue was resolved in Wowza Streaming Engine 4.8.5.

Wowza Streaming Engine 4.8.0 and earlier from multiple authenticated XSS vulnerabilities via the (1) customList%5B0%5D.value field in enginemanager/server/serversetup/edit_adv.htm of the Server Setup configuration or the (2) host field in enginemanager/j_spring_security_check of the login form. This issue was resolved in Wowza Streaming Engine 4.8.5.

Wowza Streaming Engine 4.8.0 and earlier suffers from multiple CSRF vulnerabilities. For example, an administrator, by following a link, can be tricked into making unwanted changes such as adding another admin user via enginemanager/server/user/edit.htm in the Server->Users component. This issue was resolved in Wowza Streaming Engine 4.8.5.

A Reflected XSS was found in the server selection box inside the login page at: enginemanager/loginfailed.html in Wowza Streaming Engine <= 4.x.x. This issue was resolved in Wowza Streaming Engine 4.8.0.

Wowza Streaming Engine before 4.8.5 has Insecure Permissions which may allow a local attacker to escalate privileges in / usr / local / WowzaStreamingEngine / manager / bin / in the Linux version of the server by writing arbitrary commands in any file and execute them as root. This issue was resolved in Wowza Streaming Engine 4.8.5.
