Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2024-12838 in the wild and no public exploit code.\n\nAffected product: Changing Information Technology CGFIDO. 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-2024-12838/ (Markdown: https://insights.sbomify.com/CVE-2024-12838/index.md)","id":"CVE-2024-12838","markdown":"https://insights.sbomify.com/CVE-2024-12838/index.md","name":"CVE-2024-12838","record":{"aliases":["GHSA-hcj7-gr87-5x37"],"analysis":{"component_type":"server_software","fix_type":"no_fix_stated","impacts":["privilege_escalation","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"CGFIDO authentication system","requires_auth":"low_privilege","summary":"Remote attackers with regular privileges can bypass authentication to impersonate any user, including administrators, in CGFIDO.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"twcert","cpe":[],"cvss":{"score":8.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-302","name":"Authentication Bypass by Assumed-Immutable Data"}],"description":"The passwordless login mechanism in CGFIDO from Changing Information Technology has an Authentication Bypass vulnerability, allowing remote attackers with regular privileges to send a crafted request to switch to the identity of any user, including administrators.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Changing Information Technology CGFIDO - Authentication Bypass","id":"CVE-2024-12838","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"auth_bypass","year":"2024"},"n_packages":0,"n_references":2,"next":{"headline":"Changing Information Technology CGFIDO - Authentication Bypass","id":"CVE-2024-12839"},"packages":[],"prev":{"headline":"GPU DDK - Exploitable kernel double free on apsFenceSyncCheckpoints allocated with arbitrary size","id":"CVE-2024-12837"},"products":["CGFIDO"],"published":"2024-12-31","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"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":"total"},"state":"PUBLISHED","updated":"2024-12-31","vendors":["Changing Information Technology"]},"summary":"Remote attackers with regular privileges can bypass authentication to impersonate any user, including administrators, in CGFIDO.","url":"https://insights.sbomify.com/CVE-2024-12838/"}
