{"cve":"CVE-2017-7229","nvd":{"published":"2017-05-03T20:59:00.207","modified":"2026-06-17T01:23:54.177","status":"Modified","description":"PGP/MIME encrypted messages injected into a Vaultive O365 (before 4.5.21) frontend via IMAP or SMTP have their Content-Type changed from 'Content-Type: multipart/encrypted; protocol=\"application/pgp-encrypted\"; boundary=\"abc123abc123\"' to 'Content-Type: text/plain' - this results in the encrypted message being structured in such a way that most PGP/MIME-capable mail user agents are unable to decrypt it cleanly. The outcome is that encrypted mail passing through this device does not work (Denial of Service), and a common real-world consequence is a request to resend the mail in the clear (Information Disclosure).","cvss_v4":null,"cvss_v3":{"version":"3.0","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:H","score":9.1},"cwes":["CWE-326"],"references":["https://gist.github.com/dkg/a1998c861bf2430e0d01d586905b11cb","https://gist.github.com/dkg/a1998c861bf2430e0d01d586905b11cb"],"products":["vaultive:office_365_security"],"source":"nvd","synced_at":"2026-10-19T20:42:28.077359912+00:00"},"epss":{"cve":"CVE-2017-7229","score":0.0076,"percentile":0.55303,"date":"2026-10-31"},"kev":null,"osv":[],"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).
