An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-35946 in the wild and no public exploit code.\n\nAffected product: Owncloud Owncloud. 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-2021-35946/ (Markdown: https://insights.sbomify.com/CVE-2021-35946/index.md)","id":"CVE-2021-35946","markdown":"https://insights.sbomify.com/CVE-2021-35946/index.md","name":"CVE-2021-35946","record":{"aliases":["GHSA-9gjf-xc3f-w2j8"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["privilege_escalation","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"ownCloud server","requires_auth":"none","summary":"Attackers with database access in federated shares can elevate permissions and modify data in ownCloud servers.","user_interaction":"not_required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"owncloud","vendor":"owncloud"}],"cvss":{"score":9.8,"severity":"critical","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-269","name":"Improper Privilege Management"}],"description":"A receiver of a federated share with access to the database with ownCloud version before 10.8 could update the permissions and therefore elevate their own permissions.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"Privilege escalation in n/a","id":"CVE-2021-35946","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"owncloud:owncloud","products":["owncloud:owncloud"],"type":"privilege_escalation","year":"2021"},"n_packages":0,"n_references":2,"next":{"headline":"Information disclosure in n/a","id":"CVE-2021-35947"},"packages":[],"prev":{"headline":"Memory corruption in n/a","id":"CVE-2021-35945"},"products":["n/a"],"published":"2021-09-07","related":[{"cvss_score":9.8,"headline":"XML external entity in n/a","id":"CVE-2014-2052","kev_date_added":null,"published":"2020-02-11"},{"cvss_score":9.8,"headline":"Auth bypass in n/a","id":"CVE-2014-2048","kev_date_added":null,"published":"2018-03-26"},{"cvss_score":9.1,"headline":"Path traversal in n/a","id":"CVE-2020-28645","kev_date_added":null,"published":"2021-02-09"},{"cvss_score":9,"headline":"Command injection in n/a","id":"CVE-2015-4718","kev_date_added":null,"published":"2015-10-21"},{"cvss_score":9,"headline":"Command injection in n/a","id":"CVE-2015-7698","kev_date_added":null,"published":"2015-10-21"},{"cvss_score":8.5,"headline":"Information disclosure in n/a","id":"CVE-2016-1499","kev_date_added":null,"published":"2016-01-08"}],"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":"2024-08-04","vendors":["n/a"]},"summary":"Attackers with database access in federated shares can elevate permissions and modify data in ownCloud servers.","url":"https://insights.sbomify.com/CVE-2021-35946/"}
