{"id":"CVE-2015-20110","aliases":[],"url":"https://o3.security/vulnerability/CVE-2015-20110","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.","published":"2023-10-31T03:31:22Z","modified":"2023-11-08T18:41:14Z","cvss":{"score":7.5,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"generator-jhipster","fixedVersion":"2.23.0"}],"fix":{"url":"https://github.com/jhipster/generator-jhipster/commit/79fe5626cb1bb80f9ac86cf46980748e65d2bdbc","label":"jhipster/generator-jhipster@79fe562"},"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"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2023-11-08T18:41:14Z"}}
