An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2023-36038 and fix it if it is affected.\n\nWhat it is: CVE-2023-36038 is a high-severity denial of service vulnerability in Microsoft Visual Studio 2022, published on 14 Nov 2023. An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2023-36038 exists.\n\nAffected packages and fixed versions:\n- aspnet-core (Bitnami): affected from 8.0.0; fixed in 8.0.1\n- dotnet (Bitnami): affected all versions up to 8.0.0-rc1; fixed in 8.0.0\n- dotnet-sdk (Bitnami): affected all versions up to 8.0.0-rc1; fixed in 8.0.0\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-2023-36038/ (Markdown: https://insights.sbomify.com/CVE-2023-36038/index.md)","id":"CVE-2023-36038","markdown":"https://insights.sbomify.com/CVE-2023-36038/index.md","name":"CVE-2023-36038","record":{"aliases":["BIT-aspnet-core-2023-36038","BIT-dotnet-2023-36038","BIT-dotnet-sdk-2023-36038"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"ASP.NET Core","requires_auth":"none","summary":"Attackers can cause a denial of service in ASP.NET Core applications, requiring developers to apply security patches.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":"asp.net_core","vendor":"microsoft"},{"product":"visual_studio_2022","vendor":"microsoft"}],"cvss":{"score":8.2,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:H/E:U/RL:O/RC:C","version":"3.1"},"cwes":[{"id":"CWE-400","name":"Uncontrolled Resource Consumption"}],"description":"ASP.NET Core Denial of Service Vulnerability","ecosystems":["Bitnami"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":true,"headline":"ASP.NET Core Denial of Service Vulnerability","id":"CVE-2023-36038","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Bitnami","product":"microsoft:visual_studio_2022","products":["microsoft:visual_studio_2022"],"type":"denial_of_service","year":"2023"},"n_packages":3,"n_references":1,"next":{"headline":"Microsoft Exchange Server Spoofing Vulnerability","id":"CVE-2023-36039"},"packages":[{"ecosystem":"Bitnami","fixed":["8.0.1"],"introduced":["8.0.0"],"last_affected":[],"package":"aspnet-core","purl":"pkg:bitnami/aspnet-core","source":"BIT-aspnet-core-2023-36038"},{"ecosystem":"Bitnami","fixed":["8.0.0"],"introduced":["0","8.0.0-rc1","8.0.0-rc2"],"last_affected":["8.0.0-rc1","8.0.0-rc2"],"package":"dotnet","purl":"pkg:bitnami/dotnet","source":"BIT-dotnet-2023-36038"},{"ecosystem":"Bitnami","fixed":["8.0.0"],"introduced":["0","8.0.0-rc1","8.0.0-rc2"],"last_affected":["8.0.0-rc1","8.0.0-rc2"],"package":"dotnet-sdk","purl":"pkg:bitnami/dotnet-sdk","source":"BIT-dotnet-sdk-2023-36038"}],"prev":{"headline":"Microsoft Excel Security Feature Bypass Vulnerability","id":"CVE-2023-36037"},"products":[".NET 8.0","ASP.NET Core 8.0","Microsoft Visual Studio 2022 version 17.2","Microsoft Visual Studio 2022 version 17.4","Microsoft Visual Studio 2022 version 17.6","Microsoft Visual Studio 2022 version 17.7"],"published":"2023-11-14","related":[{"cvss_score":9.9,"headline":"ASP.NET Security Feature Bypass Vulnerability","id":"CVE-2025-55315","kev_date_added":null,"published":"2025-10-14"},{"cvss_score":9.4,"headline":"ASP.NET Core Tampering Vulnerability","id":"CVE-2026-88092","kev_date_added":null,"published":"2026-10-13"},{"cvss_score":9.1,"headline":"ASP.NET Core Elevation of Privilege Vulnerability","id":"CVE-2026-40372","kev_date_added":null,"published":"2026-04-21"},{"cvss_score":8.8,"headline":"ASP.NET Core and Visual Studio Elevation of Privilege Vulnerability","id":"CVE-2021-43877","kev_date_added":null,"published":"2021-12-15"},{"cvss_score":8.8,"headline":"Remote code execution in ASP.NET Core","id":"CVE-2020-0603","kev_date_added":null,"published":"2020-01-14"},{"cvss_score":8.8,"headline":"Elevation of privilege in ASP.NET Core","id":"CVE-2019-1302","kev_date_added":null,"published":"2019-09-11"},{"cvss_score":8.8,"headline":"ASP.NET Core allow an elevation of privilege","id":"CVE-2018-0787","kev_date_added":null,"published":"2018-03-14"}],"sources":[{"class":"attribution","licence":"Apache-2.0","name":"Bitnami","prefix":"BIT"},{"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":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-10-09","vendors":["Microsoft"]},"summary":"Attackers can cause a denial of service in ASP.NET Core applications, requiring developers to apply security patches.","url":"https://insights.sbomify.com/CVE-2023-36038/"}
