LXD, published on 5 Dec 2024. 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-2024-6156 exists.\n\nAffected packages and fixed versions:\n- github.com/canonical/lxd (Go): affected all versions; fixed in 0.0.0-20240708073652-5a492a3f0036\n- github.com/canonical/lxd (Go): affected all versions; fixed in 0.0.0-20240708073652-5a492a3f0036\n- github.com/canonical/lxd (Go): affected all versions; fixed in 0.0.0-20240708073652-5a492a3f0036\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-2024-6156/ (Markdown: https://insights.sbomify.com/CVE-2024-6156/index.md)","id":"CVE-2024-6156","markdown":"https://insights.sbomify.com/CVE-2024-6156/index.md","name":"CVE-2024-6156","record":{"aliases":["DEBIAN-CVE-2024-6156","GHSA-4c49-9fpc-hc3v","GO-2024-3312","UBUNTU-CVE-2024-6156"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["security_bypass"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"LXD container manager","requires_auth":"low_privilege","summary":"Attackers can bypass LXD PKI authentication if their certificate is in the trust store, allowing unauthorized access to the container management service.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"canonical","cpe":[{"product":"lxd","vendor":"canonical"}],"cvss":{"score":3.8,"severity":"low","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:L/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-295","name":"Improper Certificate Validation"}],"description":"Mark Laing discovered that LXD's PKI mode, until version 5.21.2, could be bypassed if the client's certificate was present in the trust store.","ecosystems":["Go"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":true,"headline":"lxd CA certificate sign check bypass","id":"CVE-2024-6156","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Go","product":null,"products":[],"type":"auth_bypass","year":"2024"},"n_packages":3,"n_references":2,"next":{"headline":"Null dereference in RobotWare 6","id":"CVE-2024-6157"},"packages":[{"ecosystem":"Go","fixed":["0.0.0-20240708073652-5a492a3f0036"],"introduced":["0"],"last_affected":[],"package":"github.com/canonical/lxd","purl":null,"source":"GHSA-4c49-9fpc-hc3v"},{"ecosystem":"Go","fixed":["0.0.0-20240708073652-5a492a3f0036"],"introduced":["0"],"last_affected":[],"package":"github.com/canonical/lxd","purl":"pkg:golang/github.com/canonical/lxd","source":"GHSA-4c49-9fpc-hc3v"},{"ecosystem":"Go","fixed":["0.0.0-20240708073652-5a492a3f0036"],"introduced":["0"],"last_affected":[],"package":"github.com/canonical/lxd","purl":"pkg:golang/github.com/canonical/lxd","source":"GO-2024-3312"}],"prev":{"headline":"Server-side request forgery in Greenshift – animation and page builder blocks","id":"CVE-2024-6155"},"products":["LXD"],"published":"2024-12-05","related":[{"cvss_score":9.9,"headline":"Instance template path traversal allows arbitrary host file write as root","id":"CVE-2026-66897","kev_date_added":null,"published":"2026-08-24"},{"cvss_score":9.9,"headline":"Cross-project cluster migration bypasses project restrictions via cluster notification flag","id":"CVE-2026-62420","kev_date_added":null,"published":"2026-08-12"},{"cvss_score":9.9,"headline":"Arbitrary File Read/Write: metadata.yaml symlink in image allows host filesystem access as root","id":"CVE-2026-63293","kev_date_added":null,"published":"2026-08-12"},{"cvss_score":9.9,"headline":"Root RCE via image backup.yaml symlink","id":"CVE-2026-63294","kev_date_added":null,"published":"2026-08-12"},{"cvss_score":9.9,"headline":"Project restriction bypass via instance migration config override","id":"CVE-2026-63296","kev_date_added":null,"published":"2026-08-12"},{"cvss_score":9.9,"headline":"Cross-project instance copy bypasses target project restrictions via TOCTOU in config merge","id":"CVE-2026-63297","kev_date_added":null,"published":"2026-08-12"},{"cvss_score":9.9,"headline":"Cross-project instance move bypasses all project restrictions allowing host command execution","id":"CVE-2026-63300","kev_date_added":null,"published":"2026-08-12"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"attribution","licence":"CC BY 4.0","name":"Go Vulnerability Database","prefix":"GO"},{"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":"2025-03-18","vendors":["Canonical Ltd."]},"summary":"Attackers can bypass LXD PKI authentication if their certificate is in the trust store, allowing unauthorized access to the container management service.","url":"https://insights.sbomify.com/CVE-2024-6156/"}
