An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: Yes. Attackers have exploited CVE-2018-8581 in the wild since at least 3 Mar 2022, including in ransomware campaigns.\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-2018-8581/ (Markdown: https://insights.sbomify.com/CVE-2018-8581/index.md)","id":"CVE-2018-8581","markdown":"https://insights.sbomify.com/CVE-2018-8581/index.md","name":"CVE-2018-8581","record":{"aliases":["GHSA-h9jh-6fmr-vvc6"],"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":"An attacker can elevate privileges on Microsoft Exchange Server, potentially gaining unauthorized administrative control over the email system.","user_interaction":"not_required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":"exchange_server","vendor":"microsoft"}],"cvss":{"score":7.4,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N","version":"3.1"},"cwes":[],"description":"An elevation of privilege vulnerability exists in Microsoft Exchange Server, aka \"Microsoft Exchange Server Elevation of Privilege Vulnerability.\" This affects Microsoft Exchange Server.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2018-12-27","github_poc":3,"max_poc_stars":367,"metasploit":0,"nuclei":0,"refs":[{"date":"2019-01-24T06:08:23Z","kind":"github_poc","ref":"https://github.com/Ridter/Exchange2domain","stars":367,"title":"CVE-2018-8581"},{"date":"2018-12-27T06:30:32Z","kind":"github_poc","ref":"https://github.com/WyAtu/CVE-2018-8581","stars":331,"title":"CVE-2018-8581 | Microsoft Exchange Server Elevation of Privilege Vulnerability"},{"date":"2018-12-28T15:47:32Z","kind":"github_poc","ref":"https://github.com/qiantu88/CVE-2018-8581","stars":5,"title":"CVE-2018-8581"}],"tier":"exploited"},"has_fix":null,"headline":"Microsoft Exchange Server Privilege Escalation","id":"CVE-2018-8581","indexable":true,"kev":{"dateAdded":"2022-03-03","dueDate":"2022-03-17","knownRansomwareCampaignUse":"Known","product":"Exchange Server","requiredAction":"Apply updates per vendor instructions.","vendorProject":"Microsoft","vulnerabilityName":"Microsoft Exchange Server Privilege Escalation Vulnerability"},"kind":"cve","links":{"ecosystem":null,"product":"microsoft:exchange_server","products":["microsoft:exchange_server"],"type":"privilege_escalation","year":"2018"},"n_packages":0,"n_references":3,"next":{"headline":"Code injection in Microsoft Office","id":"CVE-2018-8582"},"packages":[],"prev":{"headline":"Information disclosure in Microsoft SharePoint","id":"CVE-2018-8580"},"products":["Microsoft Exchange Server"],"published":"2018-11-14","related":[{"cvss_score":9.8,"headline":"Microsoft Exchange Server Privilege Escalation","id":"CVE-2024-21410","kev_date_added":"2024-02-15","published":"2024-02-13"},{"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":"FIRST CVSS licence","name":"CVSS (FIRST)"},{"class":"open","licence":"CC0","name":"PoC-in-GitHub"}],"ssvc":{"automatable":"no","exploitation":"active","technical_impact":"total"},"state":"PUBLISHED","updated":"2025-10-21","vendors":["Microsoft"]},"summary":"An attacker can elevate privileges on Microsoft Exchange Server, potentially gaining unauthorized administrative control over the email system.","url":"https://insights.sbomify.com/CVE-2018-8581/"}
