Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2015-6670 in the wild and no public exploit code.\n\nAffected product: Owncloud Owncloud Server. 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-2015-6670/ (Markdown: https://insights.sbomify.com/CVE-2015-6670/index.md)","id":"CVE-2015-6670","markdown":"https://insights.sbomify.com/CVE-2015-6670/index.md","name":"CVE-2015-6670","record":{"aliases":["GHSA-jm84-v35x-p8jw"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"ownCloud Server","requires_auth":"low_privilege","summary":"Authenticated users can read arbitrary calendars due to missing ownership checks in the export function.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"owncloud_server","vendor":"owncloud"}],"cvss":{"score":4,"severity":"medium","source":"nvd","vector":"AV:N/AC:L/Au:S/C:P/I:N/A:N","version":"2.0"},"cwes":[],"description":"ownCloud Server before 7.0.8, 8.0.x before 8.0.6, and 8.1.x before 8.1.1 does not properly check ownership of calendars, which allows remote authenticated users to read arbitrary calendars via the calid parameter to apps/calendar/export.php.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Missing authorization in n/a","id":"CVE-2015-6670","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"owncloud:owncloud_server","products":["owncloud:owncloud_server"],"type":"missing_authorization","year":"2015"},"n_packages":0,"n_references":2,"next":{"headline":"Information disclosure in n/a","id":"CVE-2015-6671"},"packages":[],"prev":{"headline":"Information disclosure in n/a","id":"CVE-2015-6668"},"products":["n/a"],"published":"2015-10-26","related":[{"cvss_score":9.8,"headline":"ownCloud Improper Authentication","id":"CVE-2023-49105","kev_date_added":"2026-08-27","published":"2023-11-21"},{"cvss_score":9,"headline":"Code injection in n/a","id":"CVE-2015-7699","kev_date_added":null,"published":"2015-10-26"},{"cvss_score":7.5,"headline":"Path traversal in n/a","id":"CVE-2015-6500","kev_date_added":null,"published":"2015-10-26"},{"cvss_score":7.5,"headline":"Code injection in n/a","id":"CVE-2014-2051","kev_date_added":null,"published":"2014-06-05"},{"cvss_score":7.5,"headline":"PHPExcel vulnerable to XXE attacks through libxml","id":"CVE-2014-2054","kev_date_added":null,"published":"2014-06-04"},{"cvss_score":7.5,"headline":"XML external entity in n/a","id":"CVE-2014-2056","kev_date_added":null,"published":"2014-06-04"},{"cvss_score":7.5,"headline":"Auth bypass in n/a","id":"CVE-2012-4392","kev_date_added":null,"published":"2012-09-05"}],"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":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-06","vendors":["n/a"]},"summary":"Authenticated users can read arbitrary calendars due to missing ownership checks in the export function.","url":"https://insights.sbomify.com/CVE-2015-6670/"}
