It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2024-21397 in the wild and no public exploit code.\n\nAffected product: Microsoft Azure File Sync. 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-2024-21397/ (Markdown: https://insights.sbomify.com/CVE-2024-21397/index.md)","id":"CVE-2024-21397","markdown":"https://insights.sbomify.com/CVE-2024-21397/index.md","name":"CVE-2024-21397","record":{"aliases":["GHSA-77qj-g9f7-xqj9"],"analysis":{"component_type":"cloud_service","fix_type":"patch","impacts":["privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Azure File Sync","requires_auth":"low_privilege","summary":"An attacker can exploit a path traversal flaw in Azure File Sync to elevate privileges within the system.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":"azure_file_sync","vendor":"microsoft"}],"cvss":{"score":5.3,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:N/I:H/A:L/E:P/RL:O/RC:C","version":"3.1"},"cwes":[{"id":"CWE-59","name":"Improper Link Resolution Before File Access"}],"description":"Microsoft Azure File Sync Elevation of Privilege Vulnerability","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":"Microsoft Azure File Sync Elevation of Privilege Vulnerability","id":"CVE-2024-21397","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"path_traversal","year":"2024"},"n_packages":0,"n_references":1,"next":{"headline":"SQL Server Native Client OLE DB Provider Remote Code Execution Vulnerability","id":"CVE-2024-21398"},"packages":[],"prev":{"headline":"Dynamics 365 Sales Spoofing Vulnerability","id":"CVE-2024-21396"},"products":["Azure File Sync"],"published":"2024-02-13","related":[{"cvss_score":7.8,"headline":"Microsoft Azure File Sync Elevation of Privilege Vulnerability","id":"CVE-2025-53729","kev_date_added":null,"published":"2025-08-12"},{"cvss_score":7,"headline":"Microsoft Azure File Sync Elevation of Privilege Vulnerability","id":"CVE-2025-29973","kev_date_added":null,"published":"2025-05-13"},{"cvss_score":4.4,"headline":"Microsoft Azure File Sync Elevation of Privilege Vulnerability","id":"CVE-2024-35253","kev_date_added":null,"published":"2024-06-11"}],"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":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-08-10","vendors":["Microsoft"]},"summary":"An attacker can exploit a path traversal flaw in Azure File Sync to elevate privileges within the system.","url":"https://insights.sbomify.com/CVE-2024-21397/"}
