NFC: Certain DESFire cards cannot be read

[gsurkov]

Describe the bug.

According to @noproto's data, two MF DESFire EV2 cards cannot be read. Attempting to read them also leads to application abnormal behaviour.

Original posts:

• First mention
• Logs with additional debug output
• Proxmark logs

More info is available in the of #3050 discussion thread.

UPDATE: Most likely happening only with HID-branded cards due to additional protocol extensions.

Reproduction

The bug could not be reproduced by any of the devs.

UPDATE: Waiting for HID cards to become available for testing (ETA: 2w...1mo)

Not sure if it's the same issue, but I can't read one of my Desfire cards with 0.94.1-rc it hangs. It works fine with 0.93.

The log says:

Yep we received those card, they are clearly differ from the standard ones. We'll include fix in next release.

[noproto]

Good morning! Sorry, I've been under the weather and missed a few updates. I did want to drop in and confirm that my DESFire cards are HID-branded. I wasn't aware HID branded DESFire EV2 cards were different from "standard" DESFire EV2 cards, but that certainly sounds correct.

I have a NXP MIFARE DESFire Ev2 that also just in some rare cases get's read successfully by the Flipper Zero as ISO 14443-4A (Unknown) but in 90% of the time it just hangs in Reading card, Don't move.... The card is a danish public transport card called Rejsekort

Here is the proxmark read log of the card:

Myki DESFire Mini 0.3K used to work before refactor, but now Myki public transport card wont read either. Stays on Reading card, Don't move. Don't have proxmark to dump unfortunately!

[skotopes]

@LeeroysHub fix is coming soon

[jkter]

With firmware 0.96.1 the problem with Reading card, Don't move... infinite loop still occurs.

According to my observations with several cards it seems that the infinite loop occurs when there is an application with unavailable key configuration present on the card.

I could read empty card without any problems. After adding an application with publicly unavailable key configuration (in my case 2N PICard), flipper gets stuck in an infinite loop while reading.

[skotopes]

@jkter probably same issues, please wait till fix will be released

[gsp8181]

I've got a few other DESFire cards that don't work

Ola money (Mumbai Metro) Rabbit (Bangkok Stored Value Card) PTV Myki Card (Melbourne), this loops with or without the parser installed

[kautzz]

Can confirm NXP DESFire EV3 stuck on „reading card don’t move…“ with fw version 0.97.1

Could check our BOM if knowing the exact part number of the NFC IC helps.

[skotopes]

@kautzz yep we are working on it. fix coming soon.

@gsp8181 do you have them? can you check them with proxmark?

[gsp8181]

@skotopes sure thing, i've got 2 PTV cards and one of the others

[bobbylapointe-ops]

Same problem here, with Xtreme or Momentum...

[gornekich]

The fix arrived in dev. Please, reopen the issue if the problem persists.

[pelrun]

Just tried to read my PTV Myki card again after installing 1.0.1 and the behaviour is unchanged. Log shows reads constantly failing with the following error:

41589083 [E][MfDesfirePoller] Failed to read free memory

I've doublechecked that the previous fix attempt made it into the release, and it appears it has, but mf_desfire_poller_read_free_memory() is returning with some other error code than MfDesfireErrorNotPresent so it still bombs out.
