Official description

A low-privileged remote attacker can exploit the ubr-logread method in wwwubr.cgi to read arbitrary files on the system. The endpoint accepts a parameter specifying the log file to open (e.g., /tmp/weblog{some_number}), but this parameter is not properly validated, allowing an attacker to modify it to reference any file and retrieve its contents.
