An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: Yes. Attackers have exploited CVE-2024-21413 in the wild since at least 6 Feb 2025.\n\nAffected product: Microsoft 365 Apps. 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-2024-21413/ (Markdown: https://insights.sbomify.com/CVE-2024-21413/index.md)","id":"CVE-2024-21413","markdown":"https://insights.sbomify.com/CVE-2024-21413/index.md","name":"CVE-2024-21413","record":{"aliases":["GHSA-9mp4-h7q5-2rgq"],"analysis":{"component_type":"desktop_application","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Microsoft Office Outlook","requires_auth":"none","summary":"Attackers can execute arbitrary code via malicious emails in Microsoft Outlook, requiring users to apply vendor patches.","user_interaction":"not_required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":"365_apps","vendor":"microsoft"},{"product":"office_2016","vendor":"microsoft"},{"product":"office_2019","vendor":"microsoft"},{"product":"office_long_term_servicing_channel","vendor":"microsoft"}],"cvss":{"score":9.8,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C","version":"3.1"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"Microsoft Outlook Remote Code Execution Vulnerability","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2024-02-15","github_poc":42,"max_poc_stars":778,"metasploit":0,"nuclei":0,"refs":[{"date":"2024-02-16T15:17:59Z","kind":"github_poc","ref":"https://github.com/xaitax/CVE-2024-21413-Microsoft-Outlook-Remote-Code-Execution-Vulnerability","stars":778,"title":"Microsoft-Outlook-Remote-Code-Execution-Vulnerability"},{"date":"2024-02-17T14:52:52Z","kind":"github_poc","ref":"https://github.com/CMNatic/CVE-2024-21413","stars":294,"title":"CVE-2024-21413 PoC for THM Lab"},{"date":"2024-02-15T19:57:38Z","kind":"github_poc","ref":"https://github.com/duy-31/CVE-2024-21413","stars":156,"title":"Microsoft Outlook Information Disclosure Vulnerability (leak password hash) - Expect Script POC"},{"date":"2024-08-31T13:18:43Z","kind":"github_poc","ref":"https://github.com/ThemeHackers/CVE-2024-21413","stars":25,"title":"CVE-2024-21413 | Microsoft Outlook Remote Code Execution Vulnerability PoC"},{"date":"2024-02-16T21:10:31Z","kind":"github_poc","ref":"https://github.com/r00tb1t/CVE-2024-21413-POC","stars":17,"title":"Microsoft Outlook Information Disclosure Vulnerability (leak password hash) - CVE-2024-21413 POC"},{"date":"2025-11-30T08:22:06Z","kind":"github_poc","ref":"https://github.com/mmathivanan17/CVE-2024-21413","stars":11,"title":"Outlook exploitation"},{"date":"2024-02-20T12:41:15Z","kind":"github_poc","ref":"https://github.com/Mdusmandasthaheer/CVE-2024-21413-Microsoft-Outlook-Remote-Code-Execution-Vulnerability","stars":5,"title":null},{"date":"2024-02-23T12:13:11Z","kind":"github_poc","ref":"https://github.com/ahmetkarakayaoffical/CVE-2024-21413-Microsoft-Outlook-Remote-Code-Execution-Vulnerability","stars":4,"title":"Bu betik, Microsoft Outlook'ta keşfedilen ve CVSS değeri 9.8 olan önemli bir güvenlik açığı olan CVE-2024-21413 için bir kavram kanıtı (PoC) sunmaktadır.
