{"id":"GHSA-4gpm-r23h-gprw","summary":"generator-jhipster allows a timing attack against validateToken due to a string comparison that stops at the first character","details":"JHipster generator-jhipster before 2.23.0 allows a timing attack against validateToken due to a string comparison that stops at the first character that is different. Attackers can guess tokens by brute forcing one character at a time and observing the timing. This of course drastically reduces the search space to a linear amount of guesses based on the token length times the possible characters.","aliases":["CVE-2015-20110"],"modified":"2023-11-08T18:41:14Z","published":"2023-10-31T03:31:22Z","database_specific":{"nvd_published_at":"2023-10-31T03:15:07Z","cwe_ids":["CWE-208","CWE-307"],"severity":"HIGH","github_reviewed":true,"github_reviewed_at":"2023-10-31T19:30:57Z"},"references":[{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2015-20110"},{"type":"WEB","url":"https://github.com/jhipster/generator-jhipster/issues/2095"},{"type":"WEB","url":"https://github.com/jhipster/generator-jhipster/commit/79fe5626cb1bb80f9ac86cf46980748e65d2bdbc"},{"type":"WEB","url":"https://github.com/jhipster/generator-jhipster/commit/7c49ab3d45dc4921b831a2ca55fb1e2a2db1ee25"},{"type":"PACKAGE","url":"https://github.com/jhipster/generator-jhipster"},{"type":"WEB","url":"https://github.com/jhipster/generator-jhipster/compare/v2.22.0...v2.23.0"}],"affected":[{"package":{"name":"generator-jhipster","ecosystem":"npm","purl":"pkg:npm/generator-jhipster"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"2.23.0"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2023/10/GHSA-4gpm-r23h-gprw/GHSA-4gpm-r23h-gprw.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:H/I:N/A:N"}]}
