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.","published":"2022-03-03T15:15:08.000Z","lastModified":"2026-06-17T04:11:23.000Z","status":"Modified","sourceIdentifier":"cve@mitre.org","cvss":{"version":"3.1","score":4.9,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:N/A:N"},"cwe":["CWE-327"],"affected":["fujifilm/apeosport-iv 7080 firmware","fujifilm/apeosport-iv 6080 firmware","fujifilm/apeosport-iv 5080 firmware","fujifilm/apeosport-iv 3065 firmware","fujifilm/apeosport-iv 3060 firmware","fujifilm/apeosport-iv 2060 firmware","fujifilm/apeosport-iv 5070 firmware","fujifilm/apeosport-iv 4070 firmware","fujifilm/apeosport-iv 3070 firmware","fujifilm/apeosport-iv c4430 firmware","fujifilm/apeosport-iv c5570 firmware","fujifilm/apeosport-iv c4470 firmware","fujifilm/apeosport-iv c3370 firmware","fujifilm/apeosport-iv c2270 firmware","fujifilm/apeosport-iv c5575 firmware","fujifilm/apeosport-iv c4475 firmware","fujifilm/apeosport-iv c3375 firmware","fujifilm/apeosport-iv c2275 firmware","fujifilm/apeosport-iv c7780 firmware","fujifilm/apeosport-iv c6680 firmware","fujifilm/apeosport-iv c5580 firmware","fujifilm/apeosport-v 4020 firmware","fujifilm/apeosport-v 4070 firmware","fujifilm/apeosport-v 5070 firmware","fujifilm/apeosport-v c3320 firmware","fujifilm/apeosport-v c5585 firmware","fujifilm/apeosport-v c6685 firmware","fujifilm/apeosport-v c7785 firmware","fujifilm/apeosport-v c7775 firmware","fujifilm/apeosport-v c6675 firmware","fujifilm/apeosport-v c5575 firmware","fujifilm/apeosport-v c4475 firmware","fujifilm/apeosport-v c3375 firmware","fujifilm/apeosport-v c2275 firmware","fujifilm/apeosport-v c7775 t2 firmware","fujifilm/apeosport-v c6675 t2 firmware","fujifilm/apeosport-v c5575 t2 firmware","fujifilm/apeosport-v c4475 t2 firmware","fujifilm/apeosport-v c3375 t2 firmware","fujifilm/apeosport-v c3373 t2 firmware","fujifilm/apeosport-v c2275 t2 firmware","fujifilm/apeosport-v c7776 firmware","fujifilm/apeosport-v c6676 firmware","fujifilm/apeosport-v c5576 firmware","fujifilm/apeosport-v c4476 firmware","fujifilm/apeosport-v c3376 firmware","fujifilm/apeosport-v c2276 firmware","fujifilm/apeosport-v c7780 firmware","fujifilm/apeosport-v c6680 firmware","fujifilm/apeosport-v c5580 firmware","fujifilm/apeosport-v c7780 t2 firmware","fujifilm/apeosport-v c6680 t2 firmware","fujifilm/apeosport-v c5580 t2 firmware","fujifilm/apeosport-vi c7771 firmware","fujifilm/apeosport-vi c6671 firmware","fujifilm/apeosport-vi c5571 firmware","fujifilm/apeosport-vi c4471 firmware","fujifilm/apeosport-vi c3371 firmware","fujifilm/apeosport-vi c3370 firmware","fujifilm/apeosport-vi c2271 firmware"],"epss":{"score":0.00685,"percentile":0.52353,"date":"2026-10-26","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"low","text":"Lower severity and a low EPSS score (0.69%).
