fix(s7commplus): restore V1 challenge wire layout by gijzelaerr · Pull Request #841 · gijzelaerr/python-snap7

gijzelaerr · 2026-08-19T14:02:44Z

Summary

restore the V1 SessionKey GET_VAR_SUBSTREAMED challenge-request layout
encode the sequence field as VLQ and retain the three-byte fill used by the working S7-1200 capture
add capture-derived regression coverage and a changelog entry

Root cause

The final refactor in #775 reused the TLS/V2 substreamed request builder for the V1 SessionKey legitimation challenge. That changed the sequence field from a one-byte VLQ to a two-byte integer and changed the fill from three to four bytes.

In the latest #710 capture, the S7-1200 accepts SessionKey setup and session activation, rejects this two-byte-longer challenge request with a V254 system event, and resets the TCP connection. The corrected request matches the earlier capture that the same PLC accepted byte-for-byte.

Validation

full suite: 1814 passed, 78 skipped
targeted S7CommPlus V2/SessionKey tests: 58 passed
full pre-commit suite passed

Hardware validation requested

@xBiggs @bvanelli could you please test this branch on your S7-1200 hardware, especially the original s7commplus.Client().connect() plus browse() reproduction from #710? A db_read() / db_write() check would also be useful if convenient.

pip install --upgrade "python-snap7 @ git+https://github.com/gijzelaerr/python-snap7.git@fix-v1-sessionkey-challenge-layout"

Fixes #710.

@gijzelaerr we unfortunatelly don't have any PLC that supports the V1 protocol. I get:

INFO s7commplus.connection: S7CommPlus connected to 192.168.101.53:102, version=V2, session=1879052252, tls=True

which means the protocol version is V2 (I assume). However, I tested the branch with the three S7-1500 plcs and they all worked for a browse + variable read.

@xBiggs @bvanelli I pushed follow-up fixes for the captured V1 response handling: non-fatal V254 SystemEvents are now consumed while waiting for the matching sequence, and fragmented V3 responses have their per-fragment HMAC removed before reassembly.

@xBiggs, could you please retest this branch on the original S7-1200 FW V4.2 reproduction (connect(), browse(), and if possible db_read()/db_write())? Given your S7-1500 < FW 2.9 report, a run there would also be valuable. For that PLC, please include a decrypted/log trace from the SessionKey SET_MULTI_VARIABLES through the additional SET_VARIABLE and subsequent GET_VAR_SUBSTREAMED/SecurityDisconnect. That will let us determine a safe model/firmware condition instead of guessing.

Install:

pip install --upgrade "python-snap7 @ git+https://github.com/gijzelaerr/python-snap7.git@fix-v1-sessionkey-challenge-layout"

Local validation is green: 1,827 passed, 78 skipped, with the full pre-commit suite passing.
