Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link."},"fix_prompt":"Check this codebase for CVE-2023-21778 and fix it if it is affected.\n\nWhat it is: CVE-2023-21778 is a high-severity command injection vulnerability in Microsoft Dynamics 365, published on 14 Feb 2023. Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2023-21778 in the wild and no public exploit code.\n\nAffected product: Microsoft Dynamics 365. 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-2023-21778/ (Markdown: https://insights.sbomify.com/CVE-2023-21778/index.md)","id":"CVE-2023-21778","markdown":"https://insights.sbomify.com/CVE-2023-21778/index.md","name":"CVE-2023-21778","record":{"aliases":["GHSA-9f7p-38pj-28rv"],"analysis":{"component_type":"desktop_application","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Dynamics 365 USD","requires_auth":"low_privilege","summary":"Attackers can execute arbitrary code on systems running Microsoft Dynamics Unified Service Desk via command injection.","user_interaction":"required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":"dynamics_365","vendor":"microsoft"}],"cvss":{"score":8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:R/S:C/C:H/I:H/A:H/E:U/RL:O/RC:C","version":"3.1"},"cwes":[{"id":"CWE-77","name":"Improper Neutralization of Special Elements used in a Command"}],"description":"Microsoft Dynamics Unified Service Desk Remote Code Execution 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 Dynamics Unified Service Desk Remote Code Execution Vulnerability","id":"CVE-2023-21778","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"microsoft:dynamics_365","products":["microsoft:dynamics_365"],"type":"command_injection","year":"2023"},"n_packages":0,"n_references":1,"next":{"headline":"Visual Studio Code Remote Code Execution Vulnerability","id":"CVE-2023-21779"},"packages":[],"prev":{"headline":"Azure App Service on Azure Stack Hub Elevation of Privilege Vulnerability","id":"CVE-2023-21777"},"products":["Microsoft Dynamics 365 Unified Service Desk"],"published":"2023-02-14","related":[{"cvss_score":9.9,"headline":"Dynamics 365 Elevation of Privilege Vulnerability","id":"CVE-2026-47647","kev_date_added":null,"published":"2026-06-18"},{"cvss_score":9.9,"headline":"Microsoft Dynamics 365 On-Premises Remote Code Execution Vulnerability","id":"CVE-2026-42898","kev_date_added":null,"published":"2026-05-12"},{"cvss_score":9.3,"headline":"Microsoft Dynamics 365 (online) Spoofing Vulnerability","id":"CVE-2026-32210","kev_date_added":null,"published":"2026-04-23"},{"cvss_score":9.1,"headline":"Microsoft Dynamics 365 On-Premises Remote Code Execution Vulnerability","id":"CVE-2026-42833","kev_date_added":null,"published":"2026-05-12"},{"cvss_score":9,"headline":"Microsoft Dynamics 365 Elevation of Privilege Vulnerability","id":"CVE-2024-38182","kev_date_added":null,"published":"2024-07-31"},{"cvss_score":8.8,"headline":"Microsoft Dynamics 365 On-Premises Remote Code Execution Vulnerability","id":"CVE-2026-65772","kev_date_added":null,"published":"2026-09-08"},{"cvss_score":8.8,"headline":"Microsoft Dynamics 365 On-Premises Remote Code Execution Vulnerability","id":"CVE-2026-77908","kev_date_added":null,"published":"2026-09-08"}],"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":"total"},"state":"PUBLISHED","updated":"2026-08-19","vendors":["Microsoft"]},"summary":"Attackers can execute arbitrary code on systems running Microsoft Dynamics Unified Service Desk via command injection.","url":"https://insights.sbomify.com/CVE-2023-21778/"}
