Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2022-31014 exists.\n\nAffected product: Nextcloud Nextcloud 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-2022-31014/ (Markdown: https://insights.sbomify.com/CVE-2022-31014/index.md)","id":"CVE-2022-31014","markdown":"https://insights.sbomify.com/CVE-2022-31014/index.md","name":"CVE-2022-31014","record":{"aliases":["GHSA-264h-3v4w-6xh2"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["data_modify","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Nextcloud Server","requires_auth":"low_privilege","summary":"Attackers can inject SMTP commands via newlines in iCalendar attachments, hijacking email sessions to send unauthorized emails or modify sender details.","user_interaction":"required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"nextcloud_server","vendor":"nextcloud"}],"cvss":{"score":5.4,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-93","name":"Improper Neutralization of CRLF Sequences"},{"id":"CWE-74","name":"Improper Neutralization of Special Elements in Output Used by a Downstream Component"}],"description":"Nextcloud server is an open source personal cloud server. Affected versions were found to be vulnerable to SMTP command injection. The impact varies based on which commands are supported by the backend SMTP server. However, the main risk here is that the attacker can then hijack an already-authenticated SMTP session and run arbitrary SMTP commands as the email user, such as sending emails to other users, changing the FROM user, and so on. As before, this depends on the configuration of the server itself, but newlines should be sanitized to mitigate such arbitrary SMTP command injection. It is recommended that the Nextcloud Server is upgraded to 22.2.8 , 23.0.5 or 24.0.1. There are no known workarounds for this issue.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":false,"headline":"SMTP Command Injection in iCalendar Attachments to emails via newlines in Nextcloud Server","id":"CVE-2022-31014","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"nextcloud:nextcloud_server","products":["nextcloud:nextcloud_server"],"type":"command_injection","year":"2022"},"n_packages":0,"n_references":3,"next":{"headline":"Uncaught Exception (due to a data race) leads to process termination in Waitress","id":"CVE-2022-31015"},"packages":[],"prev":{"headline":"Authentication bypass in Vartalap chat-server","id":"CVE-2022-31013"},"products":["security-advisories"],"published":"2022-07-05","related":[{"cvss_score":9.3,"headline":"Preview generation used third-party library not suited for user-generated content in Nextcloud server","id":"CVE-2021-32802","kev_date_added":null,"published":"2021-09-07"},{"cvss_score":9.1,"headline":"Scope of workflow operations is not validated in nextcloud server","id":"CVE-2023-26482","kev_date_added":null,"published":"2023-03-30"},{"cvss_score":8.8,"headline":"Auth bypass in Nextcloud Server","id":"CVE-2018-3775","kev_date_added":null,"published":"2018-08-12"},{"cvss_score":8.7,"headline":"Nextcloud Server password reset endpoint is not brute force protected","id":"CVE-2023-35172","kev_date_added":null,"published":"2023-06-23"},{"cvss_score":8.7,"headline":"Nextcloud Server's brute force protection allows someone to send more requests than intended","id":"CVE-2023-32320","kev_date_added":null,"published":"2023-06-22"},{"cvss_score":8.6,"headline":"Trusted servers exchange can be triggered by attacker","id":"CVE-2021-32656","kev_date_added":null,"published":"2021-06-01"},{"cvss_score":8.5,"headline":"Nextcloud Server users can make external storage mount points inaccessible for other users","id":"CVE-2023-48239","kev_date_added":null,"published":"2023-11-21"}],"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":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-04-22","vendors":["nextcloud"]},"summary":"Attackers can inject SMTP commands via newlines in iCalendar attachments, hijacking email sessions to send unauthorized emails or modify sender details.","url":"https://insights.sbomify.com/CVE-2022-31014/"}
