Description

Impact

If successful login attempts are recorded, the raw tokens are stored in the log table. If a malicious person somehow views the data in the log table, he or she can obtain a raw token, which can then be used to send a request with that user's authority.

When you (1) use the following authentiactors,

and you (2) log successful login attempts, the raw tokens are stored.

Patches

Upgrade to Shield v1.0.0-beta.8 or later.

Workarounds

Disable logging for successful login attempts by the configuration files.

  • AccessTokens or HmacSha256
    • Set Config\AuthToken::$recordLoginAttempt to Auth::RECORD_LOGIN_ATTEMPT_FAILURE or Auth::RECORD_LOGIN_ATTEMPT_NONE
  • JWT
    • Set Config\AuthJWT::$recordLoginAttempt to Auth::RECORD_LOGIN_ATTEMPT_FAILURE or Auth::RECORD_LOGIN_ATTEMPT_NONE
