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-2023-3961 in the wild and no public exploit code.\n\nAffected product: Fedoraproject Fedora. 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-2023-3961/ (Markdown: https://insights.sbomify.com/CVE-2023-3961/index.md)","id":"CVE-2023-3961","markdown":"https://insights.sbomify.com/CVE-2023-3961/index.md","name":"CVE-2023-3961","record":{"aliases":["ALPINE-CVE-2023-3961","AZL-31899","AZL-37024","CLSA-2023-1700833977","CLSA-2023-1700834265","CLSA-2023-1700834882","CLSA-2023-1700835091","CLSA-2023-1700835779","CLSA-2023-1700852317","CLSA-2025-1737023462","DEBIAN-CVE-2023-3961","ECHO-d21d-5352-a8a8","GHSA-8m6h-6qw7-f6cg"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["privilege_escalation","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Samba file server","requires_auth":"none","summary":"Samba allows path traversal in pipe names, enabling clients to connect as root to external Unix domain sockets, leading to unauthorized access or crashes.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"fedora","vendor":"fedoraproject"},{"product":"enterprise_linux","vendor":"redhat"},{"product":"enterprise_linux_eus","vendor":"redhat"},{"product":"storage","vendor":"redhat"},{"product":"samba","vendor":"samba"}],"cvss":{"score":9.1,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-22","name":"Improper Limitation of a Pathname to a Restricted Directory"}],"description":"A path traversal vulnerability was identified in Samba when processing client pipe names connecting to Unix domain sockets within a private directory. Samba typically uses this mechanism to connect SMB clients to remote procedure call (RPC) services like SAMR LSA or SPOOLSS, which Samba initiates on demand. However, due to inadequate sanitization of incoming client pipe names, allowing a client to send a pipe name containing Unix directory traversal characters (../). This could result in SMB clients connecting as root to Unix domain sockets outside the private directory. If an attacker or client managed to send a pipe name resolving to an external service using an existing Unix domain socket, it could potentially lead to unauthorized access to the service and consequential adverse events, including compromise or service crashes.","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":"Samba: smbd allows client access to unix domain sockets on the file system as root","id":"CVE-2023-3961","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"fedoraproject:fedora","products":["fedoraproject:fedora","redhat:enterprise_linux","redhat:enterprise_linux_eus","samba:samba"],"type":"path_traversal","year":"2023"},"n_packages":0,"n_references":10,"next":{"headline":"Winters \u003c= 1.4.3 - Prototype Pollution to Reflected Cross-Site Scripting","id":"CVE-2023-3962"},"packages":[],"prev":{"headline":"Zavio IP Camera Stack-Based Buffer Overflow","id":"CVE-2023-3959"},"products":["Red Hat Enterprise Linux 6","Red Hat Enterprise Linux 7","Red Hat Enterprise Linux 8","Red Hat Enterprise Linux 8.6 Extended Update Support","Red Hat Enterprise Linux 8.8 Extended Update Support","Red Hat Enterprise Linux 9","Red Hat Enterprise Linux 9.0 Extended Update Support","Red Hat Enterprise Linux 9.2 Extended Update Support","Red Hat Storage 3","Red Hat Virtualization 4 for Red Hat Enterprise Linux 8"],"published":"2023-11-03","related":[{"cvss_score":9.8,"headline":"PHP-CGI OS Command Injection","id":"CVE-2024-4577","kev_date_added":"2024-06-12","published":"2024-06-09"},{"cvss_score":9.8,"headline":"Grafana Authentication Bypass","id":"CVE-2021-39226","kev_date_added":"2022-08-25","published":"2021-10-05"},{"cvss_score":9.8,"headline":"VMware ESXi and Horizon DaaS OpenSLP Heap-Based Buffer Overflow","id":"CVE-2019-5544","kev_date_added":"2021-11-03","published":"2019-12-06"},{"cvss_score":9.6,"headline":"Google Chromium V8 Type Confusion","id":"CVE-2024-4947","kev_date_added":"2024-05-20","published":"2024-05-15"},{"cvss_score":9.6,"headline":"Google Chromium Visuals Use-After-Free","id":"CVE-2024-4671","kev_date_added":"2024-05-13","published":"2024-05-09"},{"cvss_score":9.6,"headline":"Google Chromium Mojo Insufficient Data Validation","id":"CVE-2022-3075","kev_date_added":"2022-09-08","published":"2022-09-26"},{"cvss_score":9.6,"headline":"Google Chromium Indexed DB API Use-After-Free","id":"CVE-2021-30633","kev_date_added":"2021-11-03","published":"2021-10-08"}],"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":"2025-11-20","vendors":["Red Hat"]},"summary":"Samba allows path traversal in pipe names, enabling clients to connect as root to external Unix domain sockets, leading to unauthorized access or crashes.","url":"https://insights.sbomify.com/CVE-2023-3961/"}
