VULHUB ™

Apache is a popular open-source HTTP server in wide use across the Internet. Apache ships with a module called 'mod_usertrack'. This module contains code to generate unique identifiers for individual web sessions and requests. The session IDs that are generated are not not random. They are generated using the IP address of the client, the system time and the server process ID. These IDs are not meant to be used for authentication purposes. Any applications that rely on these IDs for authentication may be vulnerable to ID prediction attacks. It should be noted that this is not a vulnerability in Apache. This is only a vulnerability when an application uses these IDs to track authenticated users.
