Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2016-4027 in the wild and no public exploit code.\n\nAffected product: Open-Xchange Open-Xchange Appsuite. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2016-4027/ (Markdown: https://insights.sbomify.com/CVE-2016-4027/index.md)","id":"CVE-2016-4027","markdown":"https://insights.sbomify.com/CVE-2016-4027/index.md","name":"CVE-2016-4027","record":{"aliases":["GHSA-r9q8-r7xg-vx6c"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["account_takeover","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Open-Xchange App Suite","requires_auth":"low_privilege","summary":"Attackers on shared clients can access user accounts due to improper cookie storage during non-interactive logins, exposing authentication data.","user_interaction":"required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"open-xchange_appsuite","vendor":"open-xchange"}],"cvss":{"score":3.5,"severity":"low","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:L/UI:R/S:U/C:L/I:N/A:N","version":"3.0"},"cwes":[{"id":"CWE-200","name":"Exposure of Sensitive Information to an Unauthorized Actor"}],"description":"An issue was discovered in Open-Xchange OX App Suite before 7.8.1-rev10. 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.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Information disclosure in n/a","id":"CVE-2016-4027","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"open-xchange:open-xchange_appsuite","products":["open-xchange:open-xchange_appsuite"],"type":"information_disclosure","year":"2016"},"n_packages":0,"n_references":3,"next":{"headline":"Weak cryptography in n/a","id":"CVE-2016-4028"},"packages":[],"prev":{"headline":"Cross-site scripting in n/a","id":"CVE-2016-4026"},"products":["n/a"],"published":"2016-12-15","related":[{"cvss_score":9.9,"headline":"Server-side request forgery in n/a","id":"CVE-2017-13667","kev_date_added":null,"published":"2019-05-23"},{"cvss_score":9.8,"headline":"Denial of service in n/a","id":"CVE-2020-12645","kev_date_added":null,"published":"2020-08-31"},{"cvss_score":9.8,"headline":"Missing authorization in n/a","id":"CVE-2019-7158","kev_date_added":null,"published":"2019-06-17"},{"cvss_score":9.8,"headline":"Misconfiguration in n/a","id":"CVE-2017-17060","kev_date_added":null,"published":"2019-05-23"},{"cvss_score":9.8,"headline":"Information disclosure in n/a","id":"CVE-2017-5210","kev_date_added":null,"published":"2019-05-23"},{"cvss_score":9.8,"headline":"Missing authorization in n/a","id":"CVE-2017-5212","kev_date_added":null,"published":"2019-05-23"},{"cvss_score":9.8,"headline":"Missing authorization in n/a","id":"CVE-2017-5863","kev_date_added":null,"published":"2019-05-22"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-06","vendors":["n/a"]},"summary":"Attackers on shared clients can access user accounts due to improper cookie storage during non-interactive logins, exposing authentication data.","url":"https://insights.sbomify.com/CVE-2016-4027/"}
