An attacker that obtained access to the administrative web interface of a printer (e.g., by using the default credentials) can download the address book file, which contains the list of users (domain users, FTP users, etc.) stored on the printer, together with their encrypted passwords. The passwords are protected by a weak cipher, such as ROT13, which requires minimal effort to instantly retrieve the original password, giving the attacker a list of valid domain or FTP usernames and passwords.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:N/A:N","score":4.9},"cwes":["CWE-327"],"references":["https://www.foregenix.com/blog","https://www.foregenix.com/blogs-new-2021/dude-its-just-a-printer","https://www.fujifilm.com/fbglobal/eng/company/news/notice/2022/0302_addressbook_announce.html","https://www.foregenix.com/blog","https://www.foregenix.com/blogs-new-2021/dude-its-just-a-printer"],"products":["fujifilm:apeosport-iv_2060_firmware","fujifilm:apeosport-iv_3060_firmware","fujifilm:apeosport-iv_3065_firmware","fujifilm:apeosport-iv_3070_firmware","fujifilm:apeosport-iv_4070_firmware","fujifilm:apeosport-iv_5070_firmware","fujifilm:apeosport-iv_5080_firmware","fujifilm:apeosport-iv_6080_firmware","fujifilm:apeosport-iv_7080_firmware","fujifilm:apeosport-iv_c2270_firmware","fujifilm:apeosport-iv_c2275_firmware","fujifilm:apeosport-iv_c3370_firmware","fujifilm:apeosport-iv_c3375_firmware","fujifilm:apeosport-iv_c4430_firmware","fujifilm:apeosport-iv_c4470_firmware","fujifilm:apeosport-iv_c4475_firmware","fujifilm:apeosport-iv_c5570_firmware","fujifilm:apeosport-iv_c5575_firmware","fujifilm:apeosport-iv_c5580_firmware","fujifilm:apeosport-iv_c6680_firmware","fujifilm:apeosport-iv_c7780_firmware","fujifilm:apeosport-v_4020_firmware","fujifilm:apeosport-v_4070_firmware","fujifilm:apeosport-v_5070_firmware","fujifilm:apeosport-v_c2275_firmware","fujifilm:apeosport-v_c2275_t2_firmware","fujifilm:apeosport-v_c2276_firmware","fujifilm:apeosport-v_c3320_firmware","fujifilm:apeosport-v_c3373_t2_firmware","fujifilm:apeosport-v_c3375_firmware","fujifilm:apeosport-v_c3375_t2_firmware","fujifilm:apeosport-v_c3376_firmware","fujifilm:apeosport-v_c4475_firmware","fujifilm:apeosport-v_c4475_t2_firmware","fujifilm:apeosport-v_c4476_firmware","fujifilm:apeosport-v_c5575_firmware","fujifilm:apeosport-v_c5575_t2_firmware","fujifilm:apeosport-v_c5576_firmware","fujifilm:apeosport-v_c5580_firmware","fujifilm:apeosport-v_c5580_t2_firmware","fujifilm:apeosport-v_c5585_firmware","fujifilm:apeosport-v_c6675_firmware","fujifilm:apeosport-v_c6675_t2_firmware","fujifilm:apeosport-v_c6676_firmware","fujifilm:apeosport-v_c6680_firmware","fujifilm:apeosport-v_c6680_t2_firmware","fujifilm:apeosport-v_c6685_firmware","fujifilm:apeosport-v_c7775_firmware","fujifilm:apeosport-v_c7775_t2_firmware","fujifilm:apeosport-v_c7776_firmware"],"source":"nvd","synced_at":"2026-10-19T21:28:04.509275555+00:00"},"epss":{"cve":"CVE-2021-43774","score":0.00685,"percentile":0.5263,"date":"2026-11-01"},"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).
