| V-239702 | Medium | The vSphere UI must not show directory listings. | Enumeration techniques, such as URL parameter manipulation, rely on being able to obtain information about the web server's directory structure by locating directories without default pages. In... |
| V-239703 | Medium | vSphere UI must be configured to hide the server version. | Web servers will often display error messages to client users with enough information to aid in the debugging of the error. The information given back in error messages may display the web server... |
| V-239700 | Medium | vSphere UI must set URIEncoding to UTF-8. | Invalid user input occurs when a user inserts data or characters into a hosted application's data entry field and the hosted application is unprepared to process that data. This results in... |
| V-239701 | Medium | vSphere UI must set the welcome-file node to a default web page. | Enumeration techniques, such as URL parameter manipulation, rely on being able to obtain information about the web server's directory structure by locating directories without default pages. In... |
| V-239708 | Medium | vSphere UI log files must be moved to a permanent repository in accordance with site policy. | vSphere UI produces a handful of logs that must be offloaded from the originating system. This information can then be used for diagnostic, forensic, or other purposes relevant to ensuring the... |
| V-239709 | Medium | vSphere UI must be configured with the appropriate ports. | Web servers provide numerous processes, features, and functionalities that use TCP/IP ports. Some of these processes may be deemed unnecessary or too unsecure to run on a production system. The... |
| V-239687 | Medium | vSphere UI must generate log records for system startup and shutdown. | Logging must be started as soon as possible when a service starts and when a service is stopped. Many forms of suspicious actions can be detected by analyzing logs for unexpected service starts... |
| V-239686 | Medium | vSphere UI must record user access in a format that enables monitoring of remote access. | Remote access can be exploited by an attacker to compromise the server. By recording all remote access activities, it will be possible to determine the attacker's location, intent, and degree of... |
| V-239685 | Medium | vSphere UI must protect cookies from XSS. | Cookies are a common way to save session state over the HTTP(S) protocol. If an attacker can compromise session data stored in a cookie, they are better able to launch an attack against the server... |
| V-239684 | Medium | vSphere UI must limit the maximum size of a POST request. | The "maxPostSize" value is the maximum size in bytes of the POST that will be handled by the container FORM URL parameter parsing. Limit its size to reduce exposure to a denial-of-service... |
| V-239683 | Medium | vSphere UI must limit the number of concurrent connections permitted. | Resource exhaustion can occur when an unlimited number of concurrent requests are allowed on a website, facilitating a denial-of-service attack. Unless the number of requests is controlled, the... |
| V-239682 | Medium | vSphere UI must limit the amount of time that each TCP connection is kept alive. | Denial of service (DoS) is one threat against web servers. Many DoS attacks attempt to consume web server resources in such a way that no more resources are available to satisfy legitimate... |
