M-Files Web before 20.10.9524.1 allows a denial of service via overlapping ranges (in HTTP requests with crafted Range or Request-Range headers). NOTE: this is disputed because the range behavior is the responsibility of the web server, not the responsibility of the individual web application
The product acts as an intermediary HTTP agent (such as a proxy or firewall) in the data flow between two entities such as a client and server, but it does not interpret malformed HTTP requests or responses in ways that are consistent with how the messages will be processed by those entities that are at the ultimate destination.
