The issue arises from the server's incorrect handling of requests for byte sequences. An attacker can exploit this by amplifying the response size through repeated requests for the entire response body, as seen with an HTTP Range header value starting with the "bytes=0-,0-" substring.
Recommendations
For versions prior to 1.5.0 RC6, update to version 1.5.0 RC6 or later to resolve the issue.
