What is CVE-2024-51977?

An unauthenticated attacker can exploit a vulnerability in Brother Printers and Multifunction Devices by accessing the HTTP, HTTPS, or IPP services. By sending a GET request to the URI path /etc/mnt_info.csv, an attacker can retrieve a CSV file that contains sensitive data, including the device model, firmware version, IP address, and serial number. This exposure could lead to unauthorized access and further attacks on the network, highlighting the need for improved security measures.
