Applications using `@fastify/passport` in affected versions for user authentication, in combination with `@fastify/session` as the underlying session management mechanism, are vulnerable to session fixation attacks from network and same-site attackers. fastify applications rely on the `@fastify/passport` library for user authentication. The login and user validation are performed by the `authenticate` function. When executing this function, the `sessionId` is preserved between the pre-login and the authenticated session. Network and same-site attackers can hijack the victim's session by tossing a valid `sessionId` cookie in the victim's browser and waiting for the victim to log in on the website. As a solution, newer versions of `@fastify/passport` regenerate `sessionId` upon login, preventing the attacker-controlled pre-session cookie from being upgraded to an authenticated session. Users are advised to upgrade. There are no known workarounds for this vulnerability.","state":"PUBLIC","assigner":"security-advisories@github.com","published_at":"2023-04-21 23:15:00","updated_at":"2023-05-04 14:43:00"},"problem_types":["CWE-384"],"metrics":[],"references":[{"url":"https://github.com/fastify/fastify-passport/security/advisories/GHSA-4m3m-ppvx-xgw9","name":"https://github.com/fastify/fastify-passport/security/advisories/GHSA-4m3m-ppvx-xgw9","refsource":"MISC","tags":[],"title":"Session fixation in fastify-passport · Advisory · fastify/fastify-passport · GitHub","mime":"text/html","httpstatus":"200","archivestatus":"404"},{"url":"https://github.com/fastify/fastify-passport/commit/43c82c321db58ea3e375dd475de60befbfcf2a11","name":"https://github.com/fastify/fastify-passport/commit/43c82c321db58ea3e375dd475de60befbfcf2a11","refsource":"MISC","tags":[],"title":"Merge pull request from GHSA-4m3m-ppvx-xgw9 · fastify/fastify-passport@43c82c3 · GitHub","mime":"text/html","httpstatus":"200","archivestatus":"404"},{"url":"https://owasp.org/www-community/attacks/Session_fixation","name":"https://owasp.org/www-community/attacks/Session_fixation","refsource":"MISC","tags":[],"title":"Session fixation | OWASP Foundation","mime":"text/html","httpstatus":"200","archivestatus":"200"},{"url":"https://www.cve.org/CVERecord?id=CVE-2023-29019","name":"CVE Program record","refsource":"CVE.ORG","tags":["canonical"]},{"url":"https://nvd.nist.gov/vuln/detail/CVE-2023-29019","name":"NVD vulnerability detail","refsource":"NVD","tags":["canonical","analysis"]}],"affected":[],"timeline":[],"solutions":[],"workarounds":[],"exploits":[],"credits":[],"nvd_cpes":[{"cve_year":"2023","cve_id":"29019","vulnerable":"1","versionEndIncluding":"","cpe1":"cpe","cpe2":"2.3","cpe3":"a","cpe4":"fastify","cpe5":"passport","cpe6":"*","cpe7":"*","cpe8":"*","cpe9":"*","cpe10":"*","cpe11":"node.js","cpe12":"*","cpe13":"*"}],"vendor_comments":[],"enrichments":{"kev":null,"epss":null,"legacy_qids":[]},"source_records":{"cve_program":{"data_version":"4.0","data_type":"CVE","data_format":"MITRE","CVE_data_meta":{"ID":"CVE-2023-29019","ASSIGNER":"security-advisories@github.com","STATE":"PUBLIC"},"description":{"description_data":[{"lang":"eng","value":"@fastify/passport is a port of passport authentication library for the Fastify ecosystem.
