It leads to the server's potential memory exhaustion when many malicious requests are sent. ### Details An attacker can easily flood the peer address and port for requests. ### PoC Apply the attached patch to the example and run the client multiple times. Observe how each request will create a unique histogram and how the memory consumption increases during it. ### Impact In o...
OpenTelemetry-Go Contrib is a collection of third-party packages for OpenTelemetry-Go. Prior to version 0.46.0, the grpc Unary Server Interceptor out of the box adds labels `net.peer.sock.addr` and `net.peer.sock.port` that have unbound cardinality. It leads to the server's potential memory exhaustion when many malicious requests are sent. An attacker can easily flood the peer address and port for requests. Version 0.46.0 contains a fix for this issue. As a workaround to stop being affected, a view removing the attributes can be used. The other possibility is to disable grpc metrics instrumentation by passing `otelgrpc.WithMeterProvider` option with `noop.NewMeterProvider`.
### Summary OpenTelemetry-Go Contrib has a [handler wrapper `otelhttp`](https://github.com/open-telemetry/opentelemetry-go-contrib/blob/5f7e6ad5a49b45df45f61a1deb29d7f1158032df/instrumentation/net/http/otelhttp/handler.go#L63-L65) that adds the following labels by deafult that have unbound cardinality: - `http.user_agent` - `http.method` This leads to the server's potential memory exhaustion when many malicious requests are sent to it. ### Details HTTP header User-Agent or HTTP method for requests can be easily set by an attacker to be random and long. The library internally uses [httpconv.ServerRequest](https://github.com/open-telemetry/opentelemetry-go/blob/v1.12.0/semconv/internal/v2/http.go#L159) that records every value for HTTP [method](https://github.com/open-telemetry/opentelemetry-go/blob/38e1b499c3da3107694ad2660b3888eee9c8b896/semconv/internal/v2/http.go#L204) and [User-Agent](https://github.com/open-telemetry/opentelemetry-go/blob/38e1b499c3da3107694ad2660b3888eee9c8b8...
OpenTelemetry-Go Contrib is a collection of third-party packages for OpenTelemetry-Go. A handler wrapper out of the box adds labels `http.user_agent` and `http.method` that have unbound cardinality. It leads to the server's potential memory exhaustion when many malicious requests are sent to it. HTTP header User-Agent or HTTP method for requests can be easily set by an attacker to be random and long. The library internally uses `httpconv.ServerRequest` that records every value for HTTP `method` and `User-Agent`. In order to be affected, a program has to use the `otelhttp.NewHandler` wrapper and not filter any unknown HTTP methods or User agents on the level of CDN, LB, previous middleware, etc. Version 0.44.0 fixed this issue when the values collected for attribute `http.request.method` were changed to be restricted to a set of well-known values and other high cardinality attributes were removed. As a workaround to stop being affected, `otelhttp.WithFilter()` can be used, but it requir...
