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-2021-36949 and fix it if it is affected.\n\nWhat it is: CVE-2021-36949 is a high-severity authentication bypass vulnerability in Microsoft Azure Active Directory Connect Provisioning Agent, published on 12 Aug 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-2021-36949 in the wild and no public exploit code.\n\nAffected product: Microsoft Azure Active Directory Connect Provisioning Agent. 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-2021-36949/ (Markdown: https://insights.sbomify.com/CVE-2021-36949/index.md)","id":"CVE-2021-36949","markdown":"https://insights.sbomify.com/CVE-2021-36949/index.md","name":"CVE-2021-36949","record":{"aliases":["GHSA-55wf-38cw-5f72"],"analysis":{"component_type":"cloud_service","fix_type":"patch","impacts":["security_bypass"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Azure AD Connect","requires_auth":"low_privilege","summary":"Attackers can bypass authentication in Azure AD Connect, potentially gaining unauthorized access to identity synchronization services.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":"azure_active_directory_connect","vendor":"microsoft"},{"product":"azure_active_directory_connect_provisioning_agent","vendor":"microsoft"}],"cvss":{"score":7.1,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:A/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H/E:P/RL:O/RC:C","version":"3.1"},"cwes":[{"id":"CWE-287","name":"Improper Authentication"}],"description":"Microsoft Azure Active Directory Connect Authentication Bypass Vulnerability","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2021-08-14","github_poc":1,"max_poc_stars":3,"metasploit":0,"nuclei":0,"refs":[{"date":"2021-08-14T21:05:30Z","kind":"github_poc","ref":"https://github.com/Maxwitat/Check-AAD-Connect-for-CVE-2021-36949-vulnerability","stars":3,"title":"check if Azure AD Connect is affected by the vulnerability described in CVE-2021-36949"}],"tier":"poc_unverified"},"has_fix":null,"headline":"Microsoft Azure Active Directory Connect Authentication Bypass Vulnerability","id":"CVE-2021-36949","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"auth_bypass","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Microsoft Dynamics 365 (on-premises) Cross-site Scripting Vulnerability","id":"CVE-2021-36950"},"packages":[],"prev":{"headline":"Microsoft Windows Update Medic Service Privilege Escalation","id":"CVE-2021-36948"},"products":["Azure Active Directory Connect Provisioning Agent","Microsoft Azure Active Directory Connect 1.X.Y.Z","Microsoft Azure Active Directory Connect 2.0.X.Y"],"published":"2021-08-12","related":[{"cvss_score":8.1,"headline":"Privilege escalation in Azure AD Connect","id":"CVE-2017-8613","kev_date_added":null,"published":"2017-06-29"},{"cvss_score":5.3,"headline":"Privilege escalation in Microsoft Azure Active Directory Connect","id":"CVE-2019-1000","kev_date_added":null,"published":"2019-05-16"}],"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":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-08-10","vendors":["Microsoft"]},"summary":"Attackers can bypass authentication in Azure AD Connect, potentially gaining unauthorized access to identity synchronization services.","url":"https://insights.sbomify.com/CVE-2021-36949/"}
