An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: Yes. Attackers have exploited CVE-2024-21410 in the wild since at least 15 Feb 2024.\n\nAffected product: Microsoft Exchange Server. 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-2024-21410/ (Markdown: https://insights.sbomify.com/CVE-2024-21410/index.md)","id":"CVE-2024-21410","markdown":"https://insights.sbomify.com/CVE-2024-21410/index.md","name":"CVE-2024-21410","record":{"aliases":["GHSA-mv5v-r4x4-qmxw"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"Microsoft Exchange Server","requires_auth":"none","summary":"Attackers can exploit an authentication bypass in Microsoft Exchange Server to gain elevated privileges on the mail server.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":"exchange_server","vendor":"microsoft"}],"cvss":{"score":9.8,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H/E:F/RL:O/RC:C","version":"3.1"},"cwes":[{"id":"CWE-287","name":"Improper Authentication"}],"description":"Microsoft Exchange Server Elevation of Privilege Vulnerability","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2026-03-27","github_poc":1,"max_poc_stars":0,"metasploit":0,"nuclei":0,"refs":[{"date":"2026-03-27T12:38:19Z","kind":"github_poc","ref":"https://github.com/Piyush20004/SentinelStream-AI","stars":0,"title":"SentinelStream AI: A professional SIEM and SOAR platform featuring real-time threat correlation for CVE-2024-21410 and automated incident response logic."}],"tier":"exploited"},"has_fix":null,"headline":"Microsoft Exchange Server Privilege Escalation","id":"CVE-2024-21410","indexable":true,"kev":{"dateAdded":"2024-02-15","dueDate":"2024-03-07","knownRansomwareCampaignUse":"Unknown","product":"Exchange Server","requiredAction":"Apply mitigations per vendor instructions or discontinue use of the product if mitigations are unavailable.","vendorProject":"Microsoft","vulnerabilityName":"Microsoft Exchange Server Privilege Escalation Vulnerability"},"kind":"cve","links":{"ecosystem":null,"product":"microsoft:exchange_server","products":["microsoft:exchange_server"],"type":"auth_bypass","year":"2024"},"n_packages":0,"n_references":1,"next":{"headline":"Skype for Consumer Remote Code Execution Vulnerability","id":"CVE-2024-21411"},"packages":[],"prev":{"headline":".NET, .NET Framework, and Visual Studio Remote Code Execution Vulnerability","id":"CVE-2024-21409"},"products":["Microsoft Exchange Server 2016 Cumulative Update 23","Microsoft Exchange Server 2019 Cumulative Update 13","Microsoft Exchange Server 2019 Cumulative Update 14"],"published":"2024-02-13","related":[{"cvss_score":9.1,"headline":"Microsoft Exchange Server Remote Code Execution","id":"CVE-2021-34473","kev_date_added":"2021-11-03","published":"2021-07-14"},{"cvss_score":9.1,"headline":"Microsoft Exchange Server Remote Code Execution","id":"CVE-2021-26855","kev_date_added":"2021-11-03","published":"2021-03-02"},{"cvss_score":9,"headline":"Microsoft Exchange Server Privilege Escalation","id":"CVE-2021-34523","kev_date_added":"2021-11-03","published":"2021-07-14"},{"cvss_score":8.8,"headline":"Microsoft Exchange Server Deserialization of Untrusted Data","id":"CVE-2023-21529","kev_date_added":"2026-04-13","published":"2023-02-14"},{"cvss_score":8.8,"headline":"Microsoft Exchange Server Privilege Escalation","id":"CVE-2022-41080","kev_date_added":"2023-01-10","published":"2022-11-09"},{"cvss_score":8.8,"headline":"Microsoft Exchange Server Server-Side Request Forgery","id":"CVE-2022-41040","kev_date_added":"2022-09-30","published":"2022-10-03"}],"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":"open","licence":"CC0 1.0","name":"CISA KEV"},{"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":"yes","exploitation":"active","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-08-10","vendors":["Microsoft"]},"summary":"Attackers can exploit an authentication bypass in Microsoft Exchange Server to gain elevated privileges on the mail server.","url":"https://insights.sbomify.com/CVE-2024-21410/"}
