It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2011-1831 in the wild and no public exploit code.\n\nAffected product: n/a. 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-2011-1831/ (Markdown: https://insights.sbomify.com/CVE-2011-1831/index.md)","id":"CVE-2011-1831","markdown":"https://insights.sbomify.com/CVE-2011-1831/index.md","name":"CVE-2011-1831","record":{"aliases":["DEBIAN-CVE-2011-1831","GHSA-3699-7c24-vh7q"],"analysis":{"component_type":"operating_system","fix_type":"upgrade","impacts":["privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux ecryptfs utilities","requires_auth":"low_privilege","summary":"Local attackers can gain privileges by replacing directories with new filesystems due to improper mountpoint permission checks in ecryptfs-utils.","user_interaction":"not_required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"canonical","cpe":[{"product":"ecryptfs-utils","vendor":"ecryptfs"},{"product":"ecryptfs_utils","vendor":"ecryptfs"}],"cvss":{"score":4.6,"severity":"medium","source":"nvd","vector":"AV:L/AC:L/Au:N/C:P/I:P/A:P","version":"2.0"},"cwes":[{"id":"CWE-264","name":null}],"description":"utils/mount.ecryptfs_private.c in ecryptfs-utils before 90 does not properly check mountpoint permissions, which allows local users to effectively replace any directory with a new filesystem, and consequently gain privileges, via a mount system call.","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":"Privilege escalation in n/a","id":"CVE-2011-1831","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"privilege_escalation","year":"2011"},"n_packages":0,"n_references":4,"next":{"headline":"Missing authorization in n/a","id":"CVE-2011-1832"},"packages":[],"prev":{"headline":"Ekiga attempts to dlopen /tmp/ekiga_test.so","id":"CVE-2011-1830"},"products":["n/a"],"published":"2014-02-15","related":[{"cvss_score":5,"headline":"Weak cryptography in n/a","id":"CVE-2014-9687","kev_date_added":null,"published":"2015-03-16"},{"cvss_score":4.6,"headline":"Missing authorization in n/a","id":"CVE-2011-1836","kev_date_added":null,"published":"2014-02-15"},{"cvss_score":4.4,"headline":"Race condition in n/a","id":"CVE-2011-1835","kev_date_added":null,"published":"2014-02-15"},{"cvss_score":3.6,"headline":"Privilege escalation in n/a","id":"CVE-2011-1837","kev_date_added":null,"published":"2014-02-15"},{"cvss_score":2.1,"headline":"Missing authorization in n/a","id":"CVE-2011-1832","kev_date_added":null,"published":"2014-02-15"},{"cvss_score":2.1,"headline":"Security feature bypass in n/a","id":"CVE-2011-1834","kev_date_added":null,"published":"2014-02-15"}],"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":"Local attackers can gain privileges by replacing directories with new filesystems due to improper mountpoint permission checks in ecryptfs-utils.","url":"https://insights.sbomify.com/CVE-2011-1831/"}
