{"id":"GHSA-w8vh-p74j-x9xp","summary":"yii2-authclient vulnerable to possible timing attack on string comparison in OAuth1, OAuth2 and OpenID Connect implementation","details":"### Impact\n_What kind of vulnerability is it? Who is impacted?_\n\nOriginal Report:\n\n\u003e The Oauth1/2 \"state\" and OpenID Connect \"nonce\" is vulnerable for a \"timing attack\" since it's compared via regular string \n\u003e comparison (instead of `Yii::$app-\u003egetSecurity()-\u003ecompareString()`).\n\nAffected Code:\n\n1. OAuth 1 \"state\"\n\n    https://github.com/yiisoft/yii2-authclient/blob/0d1c3880f4d79e20aa1d77c012650b54e69695ff/src/OAuth1.php#L158\n\n3. OAuth 2 \"state\"\n    \n    https://github.com/yiisoft/yii2-authclient/blob/0d1c3880f4d79e20aa1d77c012650b54e69695ff/src/OAuth2.php#L121\n\n4. OpenID Connect \"nonce\"\n    \n    https://github.com/yiisoft/yii2-authclient/blob/0d1c3880f4d79e20aa1d77c012650b54e69695ff/src/OpenIdConnect.php#L420\n\n\n### Patches\n_Has the problem been patched? What versions should users upgrade to?_\n\nTBD: Replace strcmp with  `Yii::$app-\u003egetSecurity()-\u003ecompareString()`).\n\n### Workarounds\n_Is there a way for users to fix or remediate the vulnerability without upgrading?_\n\nnot as far as I see.\n\n### References\n_Are there any links users can visit to find out more?_\n","aliases":["CVE-2023-50708"],"modified":"2024-01-02T05:51:12.575791Z","published":"2023-12-18T20:01:00Z","database_specific":{"github_reviewed_at":"2023-12-18T20:01:00Z","nvd_published_at":"2023-12-22T19:15:08Z","cwe_ids":["CWE-203"],"severity":"LOW","github_reviewed":true},"references":[{"type":"WEB","url":"https://github.com/yiisoft/yii2-authclient/security/advisories/GHSA-w8vh-p74j-x9xp"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-50708"},{"type":"WEB","url":"https://github.com/yiisoft/yii2-authclient/commit/dabddf2154ab7e7703740205a069202554089248"},{"type":"PACKAGE","url":"https://github.com/yiisoft/yii2-authclient"},{"type":"WEB","url":"https://github.com/yiisoft/yii2-authclient/blob/0d1c3880f4d79e20aa1d77c012650b54e69695ff/src/OAuth1.php#L158"},{"type":"WEB","url":"https://github.com/yiisoft/yii2-authclient/blob/0d1c3880f4d79e20aa1d77c012650b54e69695ff/src/OAuth2.php#L121"},{"type":"WEB","url":"https://github.com/yiisoft/yii2-authclient/blob/0d1c3880f4d79e20aa1d77c012650b54e69695ff/src/OpenIdConnect.php#L420"}],"affected":[{"package":{"name":"yiisoft/yii2-authclient","ecosystem":"Packagist","purl":"pkg:composer/yiisoft/yii2-authclient"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.2.15"}]}],"versions":["2.0.0","2.0.0-beta","2.0.0-rc","2.0.1","2.0.2","2.0.3","2.0.4","2.0.5","2.0.6","2.1.0","2.1.1","2.1.2","2.1.3","2.1.4","2.1.5","2.1.6","2.1.7","2.1.8","2.2.0","2.2.1","2.2.10","2.2.11","2.2.12","2.2.13","2.2.14","2.2.2","2.2.3","2.2.4","2.2.5","2.2.6","2.2.7","2.2.8","2.2.9"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2023/12/GHSA-w8vh-p74j-x9xp/GHSA-w8vh-p74j-x9xp.json","last_known_affected_version_range":"\u003c= 2.2.14"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:C/C:N/I:N/A:N"}]}
