Its RSA PKCS1 v1.5 decryption implementation does not detect ciphertext modification by prepending '\\0' bytes to ciphertexts (it decrypts modified ciphertexts without error). An attacker might prepend these bytes with the goal of triggering memory corruption issues.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":9.8},"cwes":["CWE-119"],"references":["https://github.com/kjur/jsrsasign/issues/439","https://github.com/kjur/jsrsasign/releases/tag/8.0.17","https://github.com/kjur/jsrsasign/releases/tag/8.0.18","https://kjur.github.io/jsrsasign/","https://security.netapp.com/advisory/ntap-20200724-0001/"],"products":["kjur:jsrsasign","netapp:max_data"],"source":"nvd","synced_at":"2026-10-19T21:05:42.039641217+00:00"},"epss":{"cve":"CVE-2020-14967","score":0.0227,"percentile":0.83056,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-xxxq-chmp-67g4","url":"https://osv.dev/vulnerability/GHSA-xxxq-chmp-67g4","summary":"RSA PKCS#1 decryption vulnerability with prepending zeros in jsrsasign","modified":"2023-11-08T04:02:28.135196Z","packages":[{"ecosystem":"npm","name":"jsrsasign","purl":"pkg:npm/jsrsasign","ranges":["<8.0.18"],"fixed":["8.0.18"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
