Echo: X-Real-IP extractor trusts the header value instead of the sending peer

Impact In Echo v5, ExtractIPFromRealIPHeader checked whether the address supplied in X-Real-IP belonged to a trusted range instead of checking the address of the direct network peer. An untrusted client could therefore supply a loopback or private address and have it returned by c.RealIP with the...

Echo: WebSocket proxy can retain connections and handlers after client disconnect

Impact Echo's Proxy middleware could retain a handler, copy goroutines and network connections after a WebSocket client disconnected if the upstream kept its connection open. The raw proxy waited for both copy directions to finish without reliably closing the other connection when one direction...

Echo: Decompress permits unbounded gzip expansion in v4

Impact Echo v4's opt-in Decompress middleware exposed a gzip-decoded request stream without limiting its expanded size. A small compressed request could therefore produce a very large decoded body. Handlers that read or bind that body could consume excessive memory or CPU, and repeated or...

Echo: Rejected WebSocket upgrades can bypass Echo route-level access controls

Impact Echo's Proxy middleware selected a raw tunnel when the client requested a WebSocket upgrade, before validating whether the configured upstream accepted it. If the upstream returned an ordinary HTTP response and kept the connection alive, subsequent HTTP requests on that connection were...

Echo: BodyDump can discard BodyLimit overflow errors for unknown-length requests

Impact Echo v5's BodyDump middleware captured a bounded prefix, drained the remaining request body while ignoring read errors, and then replaced the body with the captured prefix. With an outer BodyLimit, an unknown-length request such as an HTTP/1.1 chunked request, and a BodyDump capture limit...

Echo: BodyDump captures request and response bodies without size limits in v4

Impact Echo v4's opt-in BodyDump middleware read complete request bodies into memory and retained complete response bodies without a capture limit. A client able to submit large requests to a route using BodyDump could cause large allocations before the application handler ran. Large responses,...

A flaw was found in libslirp. When handling ICMP echo requests, the reply length is not updated to match the actual data received from the host. Under specific conditions where the normal ICMP socket is unavailable, this length mismatch causes the host's real IP address to be leaked to the guest ...
