Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2023-36899 in the wild and no public exploit code.\n\nAffected product: Microsoft .Net Framework. 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-2023-36899/ (Markdown: https://insights.sbomify.com/CVE-2023-36899/index.md)","id":"CVE-2023-36899","markdown":"https://insights.sbomify.com/CVE-2023-36899/index.md","name":"CVE-2023-36899","record":{"aliases":["GHSA-fvh3-94pw-fvcc"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"Microsoft .NET Framework","requires_auth":"low_privilege","summary":"An attacker can exploit this vulnerability in Microsoft .NET Framework to elevate privileges on the affected system.","user_interaction":"not_required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":".net_framework","vendor":"microsoft"}],"cvss":{"score":8.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H/E:P/RL:O/RC:C","version":"3.1"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"ASP.NET Elevation of Privilege Vulnerability","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2023-08-11","github_poc":2,"max_poc_stars":33,"metasploit":0,"nuclei":0,"refs":[{"date":"2023-08-15T23:36:17Z","kind":"github_poc","ref":"https://github.com/midisec/CVE-2023-36899","stars":33,"title":"CVE-2023-36899漏洞的复现环境和工具，针对ASP.NET框架中的无cookie会话身份验证绕过。"},{"date":"2023-08-11T14:33:19Z","kind":"github_poc","ref":"https://github.com/d0rb/CVE-2023-36899","stars":5,"title":"CVE-2023-36899 PoC"}],"tier":"poc_unverified"},"has_fix":null,"headline":"ASP.NET Elevation of Privilege Vulnerability","id":"CVE-2023-36899","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"microsoft:.net_framework","products":["microsoft:.net_framework"],"type":"privilege_escalation","year":"2023"},"n_packages":0,"n_references":1,"next":{"headline":"Windows Common Log File System Driver Elevation of Privilege Vulnerability","id":"CVE-2023-36900"},"packages":[],"prev":{"headline":"Tablet Windows User Interface Application Core Remote Code Execution Vulnerability","id":"CVE-2023-36898"},"products":["Microsoft .NET Framework 2.0 Service Pack 2","Microsoft .NET Framework 3.5 AND 4.6.2/4.7/4.7.1/4.7.2","Microsoft .NET Framework 3.5 AND 4.7.2","Microsoft .NET Framework 3.5 AND 4.8","Microsoft .NET Framework 3.5 AND 4.8.1","Microsoft .NET Framework 3.5 and 4.6.2","Microsoft .NET Framework 4.6.2","Microsoft .NET Framework 4.6.2/4.7/4.7.1/4.7.2","Microsoft .NET Framework 4.8"],"published":"2023-08-08","related":[{"cvss_score":9.8,"headline":"Microsoft .NET Framework Remote Code Execution","id":"CVE-2020-0646","kev_date_added":"2021-11-03","published":"2020-01-14"},{"cvss_score":7.8,"headline":"Microsoft .NET Framework Remote Code Execution","id":"CVE-2017-8759","kev_date_added":"2021-11-03","published":"2017-09-13"},{"cvss_score":7.8,"headline":"Microsoft Windows Remote Code Execution","id":"CVE-2015-1671","kev_date_added":"2022-05-25","published":"2015-05-13"},{"cvss_score":7.5,"headline":"Microsoft .NET Framework Information Disclosure","id":"CVE-2024-29059","kev_date_added":"2025-02-04","published":"2024-03-22"},{"cvss_score":10,"headline":"Privilege escalation in n/a","id":"CVE-2014-4073","kev_date_added":null,"published":"2014-10-15"},{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2014-4121","kev_date_added":null,"published":"2014-10-15"},{"cvss_score":10,"headline":"Code injection in n/a","id":"CVE-2014-1806","kev_date_added":null,"published":"2014-05-14"}],"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)"},{"class":"open","licence":"CC0","name":"PoC-in-GitHub"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-08-10","vendors":["Microsoft"]},"summary":"An attacker can exploit this vulnerability in Microsoft .NET Framework to elevate privileges on the affected system.","url":"https://insights.sbomify.com/CVE-2023-36899/"}
