## Affected
NanoMQ 0.4.5
DJBHashn @ nng/src/sp/protocol/mqtt/mqtt_parser.c:675 as called from tcptran_pipe_send_start @ nng/src/sp/transport/tcp/tcp.c:743
## How to Reproduce
Send the below CONNECT message to NanoMQ:
```
"\x10\x28\x00\x02\x4d\x51\x54\x54\x04\xc2\x00\x3c\x00\x0b\x74\x65" \

"\x00\x08\x70\x61\x73\x73\x77\x6f\x72\x64"
```
The field triggering the issue in the above message is `mqtt.proto_len` with value `\x00\x02` (bytes #3-4).

"emqx",
"nanomq"
] | When the MQTT packet length is tampered with and is lower than expected, a `memcpy` [1] operation receives a `size` value that makes the source buffer location points to or into an unallocated memory area. As a result, nanomq crashes.
The below `connect` message can be used to reproduce the issue.
```
"\x10\x07\x00\x04\x4d\x51\x54\x54\x04\xc2\x00\x3c\x00\x0b\x74\x65" +\
"\x73\x74\x2d\x70\x79\x74\x68\x6f\x6e\x00\x05\x61\x64\x6d\x69\x6e" +\
"\x00\x08\x70\x61\x73\x73\x77\x6f\x72\x64"
```
As a result of the above message, `memcpy` receives a very large positive number (0xfffffffc in case of this proof of concept) as the `size` argument.
The problem seems to be with how the payload length is calculated [2]. Suspected that the unusual packet length `msg_len` is a smaller value than `used_pos`, therefore the subtraction results in a negative number. However, `memcpy` expects the size as `size_t`, which is *unsigned*. Therefore, due to the "casting" of a negative number to `size_t` the length becomes a very large positive number (0xfffffffc in case of this proof of concept).

"emqx",
"nanomq"
] | I would like to create a PoC for implementing a QoS level 3, where the incoming messages are directly published to Kafka using librdkafka.
Could you please suggest the best place in the code where the message is available for publishing forward to Kafka as well to back to the client to confirm that the message was persisted?
Another possibility would be to subscrible normaly with a client that will persist the messages to kafka, but on nanomq internals be able to detect when the subscriber is connected or not to reply back to the MQTT client at QoS 1/2. | Extending QoS to level 3 | https://api.github.com/repos/nanomq/nanomq/issues/195/comments | 3 | 2021-08-05T17:00:53Z | 2024-02-28T13:12:53Z | https://github.com/nanomq/nanomq/issues/195 | 962,020,568 | 195 |
