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-2020-0789 and fix it if it is affected.\n\nWhat it is: CVE-2020-0789 is a high-severity denial of service vulnerability in Microsoft Visual Studio 2019, published on 12 Mar 2020. 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-2020-0789 in the wild and no public exploit code.\n\nAffected product: Microsoft Visual Studio 2019. 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-2020-0789/ (Markdown: https://insights.sbomify.com/CVE-2020-0789/index.md)","id":"CVE-2020-0789","markdown":"https://insights.sbomify.com/CVE-2020-0789/index.md","name":"CVE-2020-0789","record":{"aliases":["GHSA-9p8g-4m8r-qpv5"],"analysis":{"component_type":"desktop_application","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Visual Studio Extension Installer","requires_auth":"low_privilege","summary":"An attacker can cause a denial of service in the Visual Studio Extension Installer Service by exploiting improper hard link handling.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":"visual_studio_2019","vendor":"microsoft"}],"cvss":{"score":7.1,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-59","name":"Improper Link Resolution Before File Access"}],"description":"A denial of service vulnerability exists when the Visual Studio Extension Installer Service improperly handles hard links, aka 'Visual Studio Extension Installer Service Denial of Service 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":"Denial of service in Microsoft Visual Studio 2019","id":"CVE-2020-0789","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"microsoft:visual_studio_2019","products":["microsoft:visual_studio_2019"],"type":"denial_of_service","year":"2020"},"n_packages":0,"n_references":1,"next":{"headline":"Microsoft splwow64 Elevation of Privilege Vulnerability","id":"CVE-2020-0790"},"packages":[],"prev":{"headline":"Privilege escalation in Windows","id":"CVE-2020-0788"},"products":["Microsoft Visual Studio 2019","Microsoft Visual Studio 2019 version 16.4 (includes 16.0 - 16.3)"],"published":"2020-03-12","related":[{"cvss_score":8.8,"headline":"Visual Studio Remote Code Execution Vulnerability","id":"CVE-2021-27068","kev_date_added":null,"published":"2021-05-11"},{"cvss_score":7.8,"headline":"Visual Studio Remote Code Execution Vulnerability","id":"CVE-2025-32702","kev_date_added":null,"published":"2025-05-13"},{"cvss_score":7.8,"headline":"Visual Studio Elevation of Privilege Vulnerability","id":"CVE-2023-28262","kev_date_added":null,"published":"2023-04-11"},{"cvss_score":7.3,"headline":"Visual Studio Elevation of Privilege Vulnerability","id":"CVE-2025-25003","kev_date_added":null,"published":"2025-03-11"},{"cvss_score":6.7,"headline":"Visual Studio Elevation of Privilege Vulnerability","id":"CVE-2023-36759","kev_date_added":null,"published":"2023-09-12"},{"cvss_score":6.2,"headline":"Visual Studio Denial of Service Vulnerability","id":"CVE-2023-36042","kev_date_added":null,"published":"2023-11-14"}],"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":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-04","vendors":["Microsoft"]},"summary":"An attacker can cause a denial of service in the Visual Studio Extension Installer Service by exploiting improper hard link handling.","url":"https://insights.sbomify.com/CVE-2020-0789/"}
