Security vulnerabilities and automated fixes for httpd issues

A critical vulnerability in an embedded HTTP server allowed any unauthenticated attacker to upload and flash arbitrary firmware images to a network switch — no credentials required. Because malicious firmware survives reboots and factory resets, a successful attack could permanently compromise an entire fleet of devices with backdoors or rootkits. The fix adds an authentication gate and corrects dangerous CRC-check logic that would reset the device even on a failed checksum.
