It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2022-41882 in the wild and no public exploit code.\n\nAffected product: nextcloud security-advisories. 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-2022-41882/ (Markdown: https://insights.sbomify.com/CVE-2022-41882/index.md)","id":"CVE-2022-41882","markdown":"https://insights.sbomify.com/CVE-2022-41882/index.md","name":"CVE-2022-41882","record":{"aliases":["DEBIAN-CVE-2022-41882","GHSA-3w86-rm38-8w63","UBUNTU-CVE-2022-41882"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Nextcloud Desktop Client","requires_auth":"low_privilege","summary":"Attackers can execute arbitrary code on Windows systems by tricking users into clicking malicious nc:// links in synced files.","user_interaction":"required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"desktop","vendor":"nextcloud"}],"cvss":{"score":6.6,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:R/S:C/C:L/I:H/A:L","version":"3.1"},"cwes":[{"id":"CWE-94","name":"Improper Control of Generation of Code"}],"description":"The Nextcloud Desktop Client is a tool to synchronize files from Nextcloud Server with your computer. In version 3.6.0, if a user received a malicious file share and has it synced locally or the virtual filesystem enabled and clicked a nc://open/ link it will open the default editor for the file type of the shared file, which on Windows can also sometimes mean that a file depending on the type, e.g. \"vbs\", is being executed. It is recommended that the Nextcloud Desktop client is upgraded to version 3.6.1. As a workaround, users can block the Nextcloud Desktop client 3.6.0 by setting the `minimum.supported.desktop.version` system config to `3.6.1` on the server, so new files designed to use this attack vector are not downloaded anymore. Already existing files can still be used. Another workaround would be to enforce shares to be accepted by setting the `sharing.force_share_accept` system config to `true` on the server, so new files designed to use this attack vector are not downloaded anymore. Already existing shares can still be abused.","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":"Nextcloud Desktop vulnerable to code injection via malicious link","id":"CVE-2022-41882","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"code_injection","year":"2022"},"n_packages":0,"n_references":4,"next":{"headline":"Out of bounds segmentation fault due to unequal op inputs in Tensorflow","id":"CVE-2022-41883"},"packages":[],"prev":{"headline":"HAProxyMessageDecoder Stack Exhaustion DoS","id":"CVE-2022-41881"},"products":["security-advisories"],"published":"2022-11-11","related":[{"cvss_score":9.1,"headline":"Misconfiguration in n/a","id":"CVE-2024-46958","kev_date_added":null,"published":"2024-09-16"},{"cvss_score":7.8,"headline":"Code injection in Desktop Client","id":"CVE-2020-8224","kev_date_added":null,"published":"2020-08-10"},{"cvss_score":7.5,"headline":"Information disclosure in Desktop Client","id":"CVE-2020-8225","kev_date_added":null,"published":"2020-09-18"},{"cvss_score":7.3,"headline":"Untrusted Search Path in Nextcloud Desktop Client","id":"CVE-2021-37617","kev_date_added":null,"published":"2021-08-18"},{"cvss_score":6.9,"headline":"Nextcloud: Lack of authenticity of metadata keys allows a malicious server to gain access to E2EE folders","id":"CVE-2023-28999","kev_date_added":null,"published":"2023-04-04"},{"cvss_score":6.8,"headline":"Path traversal in Desktop Client","id":"CVE-2020-8227","kev_date_added":null,"published":"2020-08-21"},{"cvss_score":6.7,"headline":"Nextcloud Desktop: Initialization vector reuse in E2EE allows malicious server admin to break, manipulate, access files","id":"CVE-2023-28997","kev_date_added":null,"published":"2023-04-04"}],"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":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-04-23","vendors":["nextcloud"]},"summary":"Attackers can execute arbitrary code on Windows systems by tricking users into clicking malicious nc:// links in synced files.","url":"https://insights.sbomify.com/CVE-2022-41882/"}
