It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2018-13405 exists.\n\nAffected product: Canonical Ubuntu Linux. 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-2018-13405/ (Markdown: https://insights.sbomify.com/CVE-2018-13405/index.md)","id":"CVE-2018-13405","markdown":"https://insights.sbomify.com/CVE-2018-13405/index.md","name":"CVE-2018-13405","record":{"aliases":["DEBIAN-CVE-2018-13405","GHSA-5p56-pcgw-42mf","RHSA-2019:0717","RHSA-2019:2566","UBUNTU-CVE-2018-13405"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"Linux kernel","requires_auth":"low_privilege","summary":"Local attackers can escalate privileges by creating SGID executable files in writable SGID directories due to incorrect group ownership assignment.","user_interaction":"not_required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"ubuntu_linux","vendor":"canonical"},{"product":"debian_linux","vendor":"debian"},{"product":"big-ip_access_policy_manager","vendor":"f5"},{"product":"big-ip_advanced_firewall_manager","vendor":"f5"},{"product":"big-ip_analytics","vendor":"f5"},{"product":"big-ip_application_acceleration_manager","vendor":"f5"},{"product":"big-ip_application_security_manager","vendor":"f5"},{"product":"big-ip_domain_name_system","vendor":"f5"},{"product":"big-ip_edge_gateway","vendor":"f5"},{"product":"big-ip_fraud_protection_service","vendor":"f5"},{"product":"big-ip_global_traffic_manager","vendor":"f5"},{"product":"big-ip_link_controller","vendor":"f5"},{"product":"big-ip_local_traffic_manager","vendor":"f5"},{"product":"big-ip_policy_enforcement_manager","vendor":"f5"},{"product":"big-ip_webaccelerator","vendor":"f5"},{"product":"fedora","vendor":"fedoraproject"},{"product":"linux_kernel","vendor":"linux"},{"product":"enterprise_linux_aus","vendor":"redhat"},{"product":"enterprise_linux_desktop","vendor":"redhat"},{"product":"enterprise_linux_eus","vendor":"redhat"},{"product":"enterprise_linux_for_real_time","vendor":"redhat"},{"product":"enterprise_linux_server","vendor":"redhat"},{"product":"enterprise_linux_server_aus","vendor":"redhat"},{"product":"enterprise_linux_server_tus","vendor":"redhat"},{"product":"enterprise_linux_workstation","vendor":"redhat"},{"product":"mrg_realtime","vendor":"redhat"},{"product":"virtualization","vendor":"redhat"}],"cvss":{"score":7.8,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-269","name":"Improper Privilege Management"}],"description":"The inode_init_owner function in fs/inode.c in the Linux kernel through 3.16 allows local users to create files with an unintended group ownership, in a scenario where a directory is SGID to a certain group and is writable by a user who is not a member of that group.
