Technical details
A Loop with Unreachable Exit Condition ('Infinite Loop') vulnerability exists in the mod_proxy_ftp module of Apache HTTP Server. The flaw is located in the proxy_ftp_handler function and is triggered when the server interacts with an attacker-controlled or malicious backend FTP server. By sending a specifically crafted response, the backend server can cause the Apache process to enter an infinite loop, consuming CPU resources and leading to a denial-of-service (DoS). The issue is fixed in version 2.4.68.
