Tillitis: TKey Client has an Error in Protocol Implementation

4.7 MediumFix available

Tillitis TKey Client package is a Go package for a TKey client. Versions 1.2.0 and below contain a critical bug in the tkeyclient Go module which causes 1 out of every 256 User Supplied Secrets (USS) to be silently ignored, producing the same Compound Device Identifier (CDI)—and thus the same key material—as if no USS is provided. This happens because a buffer index error overwrites the USS-enabled boolean with the first byte of the USS digest, so any USS whose hash starts with 0x00 is effectively discarded. This issue has been fixed in version 1.3.0. Users unable to upgrade immediately should switch to a USS whose hash does not begin with a zero byte.

Tillitis TKey Client has an Error in Protocol Implementation

Impact

Some specific (1 out of 256) User Supplied Secrets (USS) were not used, making the resulting Compound Device Identifier (CDI) the same as if no USS was provided.

Affected client applications: all client apps using the tkeyclient Go module.

Patches

Upgrade to v1.3.0.

NOTE WELL: For the affected end users upgrading an app containing tkeyclient to v1.3.0 means their key material will change. An end user can get their old keys by not entering any USS. Please make sure to communicate this to end users.

Affected users

The steps required to assess whether your USS is vulnerable may vary depending on the client application. The example below shows how to perform the check using tkey-ssh-agent and the known vulnerable USS adl.

  1. Insert the TKey into the client
  2. Run tkey-ssh-agent -p --uss
  3. When prompted for a User Supplied Secret, enter adl
  4. Note the public key and call it pubkey-with-uss
  5. Remove the TKey from the client
  6. Insert the TKey into the client again
  7. Run tkey-ssh-agent -p
  8. Note the public key and call it pubkey-without-uss

Expected behavior: pubkey-with-uss and pubkey-without-uss should not be equal.

Observed behavior: pubkey-with-uss and pubkey-without-uss are equal.

Workaround

We recommend everyone using tkeyclient to update to v1.3.0 and release new versions of the client apps using it.

However, end users that are unable to upgrade to a new version of a client app, the recommendation is to change to an unaffected USS. Include specific instructions for your client app.

Details

When loading the device app an optional 32 bytes USS digest is also sent. The intention is to ask the end user to enter a USS of arbitrary length, hash it, and then send a 32 bytes digest to TKey.

However, there was a bug when sending the digest from the client. The index in the outgoing buffer is wrong and overwrites the boolean defining if the USS is used or not.

This means that if the USS digest begins with a 0, the rest of the digest is not used at all. If it begins with something else, setting the boolean to true, the USS is used.

The exported LoadApp() function calls an internal helper function loadApp() which contains this code:

  if len(secretPhrase) == 0 {
    tx[6] = 0
  } else {
    tx[6] = 1 // Note the 6 here
    // Hash user's phrase as USS
    uss := blake2s.Sum256(secretPhrase)
    copy(tx[6:], uss[:]) // Note that 6 is used again
  }

A side effect of this behavior is that only 31 bytes of the USS are used. This is not considered a security issue, but an option has been added to enforce use of the full USS. See the release notes for details. To avoid forcing all users to roll their keys, this option is disabled by default and must be explicitly enabled.

The fix

The fix focuses on solving the vulnerability only by: 1) use correct index, 2) always use the last 31 bytes of the USS:

  if len(secretPhrase) == 0 {
    tx[6] = 0
  } else {
    tx[6] = 1
    // Hash user's phrase as USS
    uss := blake2s.Sum256(secretPhrase)
    copy(tx[7:], uss[1:])
  }

This change means the key material of affected end users will change compared to earlier versions of tkeyclient. They have the choice of:

  1. Not using a USS and keep their keys.
  2. Keep using their USS and use new generated keys.
  3. Use another USS and thus new keys.
