Summary
yii2-authclient vulnerable to possible timing attack on string comparison in OAuth1, OAuth2 and OpenID Connect implementation
Details

Impact

What kind of vulnerability is it? Who is impacted?

Original Report:

The Oauth1/2 "state" and OpenID Connect "nonce" is vulnerable for a "timing attack" since it's compared via regular string comparison (instead of Yii::$app->getSecurity()->compareString()).

Affected Code:

  1. OAuth 1 "state"

    https://github.com/yiisoft/yii2-authclient/blob/0d1c3880f4d79e20aa1d77c012650b54e69695ff/src/OAuth1.php#L158

  2. OAuth 2 "state"

    https://github.com/yiisoft/yii2-authclient/blob/0d1c3880f4d79e20aa1d77c012650b54e69695ff/src/OAuth2.php#L121

  3. OpenID Connect "nonce"

    https://github.com/yiisoft/yii2-authclient/blob/0d1c3880f4d79e20aa1d77c012650b54e69695ff/src/OpenIdConnect.php#L420

Patches

Has the problem been patched? What versions should users upgrade to?

TBD: Replace strcmp with Yii::$app->getSecurity()->compareString()).

Workarounds

Is there a way for users to fix or remediate the vulnerability without upgrading?

not as far as I see.
