Package

composer codeigniter4/shield (Composer)

Affected versions

< 1.0.0-beta.8

Patched versions

1.0.0-beta.8

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

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
