An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2021-22912 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- nextcloud (Bitnami): affected all versions; fixed in 3.4.2\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-2021-22912/ (Markdown: https://insights.sbomify.com/CVE-2021-22912/index.md)","id":"CVE-2021-22912","markdown":"https://insights.sbomify.com/CVE-2021-22912/index.md","name":"CVE-2021-22912","record":{"aliases":["BIT-nextcloud-2021-22912","GHSA-m7w4-cvjr-76mh"],"analysis":{"component_type":"mobile_application","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Nextcloud iOS app","requires_auth":"none","summary":"Nextcloud iOS app leaks user data by querying a global lookup server during sharee searches instead of restricting to the local server.","user_interaction":"required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"hackerone","cpe":[{"product":"nextcloud","vendor":"nextcloud"}],"cvss":{"score":6.5,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-200","name":"Exposure of Sensitive Information to an Unauthorized Actor"}],"description":"Nextcloud iOS before 3.4.2 suffers from an information disclosure vulnerability when searches for sharees utilize the lookup server by default instead of only on the local Nextcloud server unless a global search has been explicitly chosen by the user.","ecosystems":["Bitnami"],"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":"Information disclosure in Nextcloud iOS app (it.twsweb.Nextcloud)","id":"CVE-2021-22912","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Bitnami","product":null,"products":[],"type":"information_disclosure","year":"2021"},"n_packages":1,"n_references":2,"next":{"headline":"Information disclosure in Nextcloud Deck","id":"CVE-2021-22913"},"packages":[{"ecosystem":"Bitnami","fixed":["3.4.2"],"introduced":["0"],"last_affected":[],"package":"nextcloud","purl":"pkg:bitnami/nextcloud","source":"BIT-nextcloud-2021-22912"}],"prev":{"headline":"Code injection in Rocket.Chat server","id":"CVE-2021-22911"},"products":["Nextcloud iOS app (it.twsweb.Nextcloud)"],"published":"2021-06-11","related":[{"cvss_score":9.8,"headline":"SQL injection in com.nextcloud.client","id":"CVE-2019-5454","kev_date_added":null,"published":"2019-07-30"},{"cvss_score":7.5,"headline":"SQL Injection in FileContentProvider (GHSL-2021-1007)","id":"CVE-2021-43863","kev_date_added":null,"published":"2022-01-25"},{"cvss_score":6.8,"headline":"Cross-site scripting in com.nextcloud.client","id":"CVE-2019-5450","kev_date_added":null,"published":"2019-07-30"},{"cvss_score":6.8,"headline":"Auth bypass in com.nextcloud.client","id":"CVE-2019-5455","kev_date_added":null,"published":"2019-07-30"},{"cvss_score":6.5,"headline":"Information disclosure in Nextcloud Android App (com.nextcloud.client)","id":"CVE-2021-22905","kev_date_added":null,"published":"2021-06-11"},{"cvss_score":6.1,"headline":"Auth bypass in Nextcloud Android","id":"CVE-2019-15615","kev_date_added":null,"published":"2020-02-04"}],"sources":[{"class":"attribution","licence":"Apache-2.0","name":"Bitnami","prefix":"BIT"},{"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":"2024-08-03","vendors":["n/a"]},"summary":"Nextcloud iOS app leaks user data by querying a global lookup server during sharee searches instead of restricting to the local server.","url":"https://insights.sbomify.com/CVE-2021-22912/"}
