CVE-2023-50708

MEDIUM

yii2-authclient < 2.2.15 - Timing Attack via OAuth State and OpenID Connect Nonce Comparison

Title source: llm
STIX 2.1

Description

yii2-authclient is an extension that adds OpenID, OAuth, OAuth2 and OpenId Connect consumers for the Yii framework 2.0. In yii2-authclient prior to version 2.2.15, the Oauth1/2 `state` and OpenID Connect `nonce` is vulnerable for a `timing attack` since it is compared via regular string comparison (instead of `Yii::$app->getSecurity()->compareString()`). Version 2.2.15 contains a patch for the issue. No known workarounds are available.
