{"id":"GHSA-jfxm-w8g2-4rcv","summary":"Cisco node-jose improper validation of JWT signature","details":"A vulnerability in the Cisco node-jose open source library before 0.11.0 could allow an unauthenticated, remote attacker to re-sign tokens using a key that is embedded within the token. The vulnerability is due to node-jose following the JSON Web Signature (JWS) standard for JSON Web Tokens (JWTs). This standard specifies that a JSON Web Key (JWK) representing a public key can be embedded within the header of a JWS. This public key is then trusted for verification. An attacker could exploit this by forging valid JWS objects by removing the original signature, adding a new public key to the header, and then signing the object using the (attacker-owned) private key associated with the public key embedded in that JWS header.","aliases":["CVE-2018-0114"],"modified":"2023-11-08T03:59:30.230514Z","published":"2022-05-13T01:17:32Z","database_specific":{"cwe_ids":["CWE-347"],"severity":"HIGH","github_reviewed":true,"github_reviewed_at":"2023-07-20T18:45:54Z","nvd_published_at":"2018-01-04T06:29:00Z"},"references":[{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2018-0114"},{"type":"PACKAGE","url":"https://github.com/cisco/node-jose"},{"type":"WEB","url":"https://github.com/cisco/node-jose/blob/master/CHANGELOG.md"},{"type":"WEB","url":"https://github.com/zi0Black/POC-CVE-2018-0114"},{"type":"WEB","url":"https://tools.cisco.com/security/center/viewAlert.x?alertId=56326"},{"type":"WEB","url":"https://web.archive.org/web/20210124130907/http://www.securityfocus.com/bid/102445"},{"type":"WEB","url":"https://www.exploit-db.com/exploits/44324"}],"affected":[{"package":{"name":"node-jose","ecosystem":"npm","purl":"pkg:npm/node-jose"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"0.11.0"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2022/05/GHSA-jfxm-w8g2-4rcv/GHSA-jfxm-w8g2-4rcv.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N"}]}
