It can only be exploited from the same machine or local network, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2021-27064 and fix it if it is affected.\n\nWhat it is: CVE-2021-27064 is a high-severity vulnerability in Microsoft Visual Studio 2017, published on 13 Apr 2021. 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-2021-27064 in the wild and no public exploit code.\n\nAffected product: Microsoft Visual Studio 2017. 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-2021-27064/ (Markdown: https://insights.sbomify.com/CVE-2021-27064/index.md)","id":"CVE-2021-27064","markdown":"https://insights.sbomify.com/CVE-2021-27064/index.md","name":"CVE-2021-27064","record":{"aliases":["GHSA-x544-2j43-9gqx"],"analysis":{"component_type":"desktop_application","fix_type":"patch","impacts":["privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Visual Studio Installer","requires_auth":"low_privilege","summary":"An attacker can exploit the Visual Studio Installer to gain elevated privileges on the local system.","user_interaction":"not_required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":"visual_studio_2017","vendor":"microsoft"},{"product":"visual_studio_2019","vendor":"microsoft"}],"cvss":{"score":7.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H/E:P/RL:O/RC:C","version":"3.1"},"cwes":[],"description":"Visual Studio Installer 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":"Visual Studio Installer Elevation of Privilege Vulnerability","id":"CVE-2021-27064","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"microsoft:visual_studio_2017","products":["microsoft:visual_studio_2017","microsoft:visual_studio_2019"],"type":"privilege_escalation","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Microsoft Exchange Server Remote Code Execution","id":"CVE-2021-27065"},"packages":[],"prev":{"headline":"Windows DNS Server Denial of Service Vulnerability","id":"CVE-2021-27063"},"products":["Microsoft Visual Studio 2017 version 15.9 (includes 15.0 - 15.8)","Microsoft Visual Studio 2019 version 16.4 (includes 16.0 - 16.3)","Microsoft Visual Studio 2019 version 16.7 (includes 16.0 – 16.6)","Microsoft Visual Studio 2019 version 16.9 (includes 16.0 - 16.8)"],"published":"2021-04-13","related":[{"cvss_score":8.8,"headline":"Visual Studio Remote Code Execution Vulnerability","id":"CVE-2025-21178","kev_date_added":null,"published":"2025-01-14"},{"cvss_score":8.8,"headline":"Code injection in Microsoft Visual Studio 2017","id":"CVE-2019-1349","kev_date_added":null,"published":"2020-01-24"},{"cvss_score":8.8,"headline":"Code injection in Microsoft Visual Studio 2017","id":"CVE-2019-1350","kev_date_added":null,"published":"2020-01-24"},{"cvss_score":8.8,"headline":"Code injection in Microsoft Visual Studio 2017","id":"CVE-2019-1352","kev_date_added":null,"published":"2020-01-24"},{"cvss_score":8.8,"headline":"Code injection in Microsoft Visual Studio 2017","id":"CVE-2019-1354","kev_date_added":null,"published":"2020-01-24"},{"cvss_score":7.8,"headline":"Visual Studio Remote Code Execution Vulnerability","id":"CVE-2023-28296","kev_date_added":null,"published":"2023-04-11"},{"cvss_score":7.8,"headline":"Visual Studio Elevation of Privilege Vulnerability","id":"CVE-2023-21566","kev_date_added":null,"published":"2023-02-14"}],"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":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2025-08-15","vendors":["Microsoft"]},"summary":"An attacker can exploit the Visual Studio Installer to gain elevated privileges on the local system.","url":"https://insights.sbomify.com/CVE-2021-27064/"}
