A vulnerability was found in the quarkus-core component. Quarkus captures the local environment variables from the Quarkus namespace during the application's build. Thus, running the resulting application inherits the values captured at build time. However, some local environment variables may have been set by the developer / CI environment for testing purposes, such as dropping the database during the application startup or trusting all TLS certificates to accept self-signed certificates. If these properties are configured using environment variables or the .env facility, they are captured into the built application. It leads to dangerous behavior if the application does not override these values. This behavior only happens for configuration properties from the `quarkus.*` namespace. So, application-specific properties are not captured.
### Summary The `HttpPostRequestDecoder` can be tricked to accumulate data. I have spotted currently two attack vectors ### Details 1. While the decoder can store items on the disk if configured so, there are no limits to the number of fields the form can have, an attacher can send a chunked post consisting of many small fields that will be accumulated in the `bodyListHttpData` list. 2. The decoder cumulates bytes in the `undecodedChunk` buffer until it can decode a field, this field can cumulate data without limits ### PoC Here is a Netty branch that provides a fix + tests : https://github.com/vietj/netty/tree/post-request-decoder Here is a reproducer with Vert.x (which uses this decoder) https://gist.github.com/vietj/f558b8ea81ec6505f1e9a6ca283c9ae3 ### Impact Any Netty based HTTP server that uses the `HttpPostRequestDecoder` to decode a form.
