{"id":"CVE-2016-9124","url":"https://www.cyber-defence.io/tools/cve/CVE-2016-9124","generatedAt":"2026-10-28T20:05:59.685Z","title":"Revive Adserver before 3.2.3 suffers from Improper Restriction of Excessive Authentication Attempts.","description":"Revive Adserver before 3.2.3 suffers from Improper Restriction of Excessive Authentication Attempts. The login page of Revive Adserver is vulnerable to password-guessing attacks. An account lockdown feature was considered, but rejected to avoid introducing service disruptions to regular users during such attacks. A random delay has instead been introduced as a countermeasure in case of password failures, along with a system to discourage parallel brute forcing. These systems will effectively allow the valid users to log in to the adserver, even while an attack is in progress.","published":"2017-03-28T02:59:00.000Z","lastModified":"2026-06-17T00:55:34.000Z","status":"Modified","sourceIdentifier":"support@hackerone.com","cvss":{"version":"3.0","score":9.8,"severity":"CRITICAL","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"},"cwe":["CWE-307","CWE-287"],"affected":["revive-adserver/revive adserver"],"epss":{"score":0.0223,"percentile":0.82662,"date":"2026-10-27","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (2.23%).
