App Suite frontend offers to control whether a user wants to store cookies that exceed the session duration. This functionality is useful when logging in from clients with reduced privileges or shared environments. However the setting was incorrectly recognized and cookies were stored regardless of this setting when the login was performed using a non-interactive login method. In case the setting was enforced by middleware configuration or the user went through the interactive login page, the workflow was correct. Cookies with authentication information may become available to other users on shared environments. In case the user did not properly log out from the session, third parties with access to the same client can access a user's account.","cvss_v4":null,"cvss_v3":{"version":"3.0","vector":"CVSS:3.0/AV:N/AC:L/PR:L/UI:R/S:U/C:L/I:N/A:N","score":3.5},"cwes":["CWE-200"],"references":["http://packetstormsecurity.com/files/137599/Open-Xchange-App-Suite-7.8.1-Information-Disclosure.html","http://www.securityfocus.com/archive/1/538732/100/0/threaded","http://www.securitytracker.com/id/1036157","http://packetstormsecurity.com/files/137599/Open-Xchange-App-Suite-7.8.1-Information-Disclosure.html","http://www.securityfocus.com/archive/1/538732/100/0/threaded"],"products":["open-xchange:open-xchange_appsuite"],"source":"nvd","synced_at":"2026-10-19T20:41:25.729257544+00:00"},"epss":{"cve":"CVE-2016-4027","score":0.0107,"percentile":0.64847,"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).
