An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2018-0940 in the wild and no public exploit code.\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-2018-0940/ (Markdown: https://insights.sbomify.com/CVE-2018-0940/index.md)","id":"CVE-2018-0940","markdown":"https://insights.sbomify.com/CVE-2018-0940/index.md","name":"CVE-2018-0940","record":{"aliases":["GHSA-272p-x79f-r2pc"],"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 exploit link rewriting in Outlook Web Access to elevate privileges within Microsoft Exchange Server.","user_interaction":"required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":"exchange_server","vendor":"microsoft"}],"cvss":{"score":6.5,"severity":"medium","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N","version":"3.0"},"cwes":[],"description":"Microsoft Exchange Outlook Web Access (OWA) in Microsoft Exchange Server 2010 Service Pack 3 Update Rollup 20, Microsoft Exchange Server 2013 Cumulative Update 18, Microsoft Exchange Server 2013 Cumulative Update 19, Microsoft Exchange Server 2013 Service Pack 1, Microsoft Exchange Server 2016 Cumulative Update 7, and Microsoft Exchange Server 2016 Cumulative Update 8 allows an elevation of privilege vulnerability due to how links in the body of an email message are rewritten, aka \"Microsoft Exchange Elevation of Privilege Vulnerability\".","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Privilege escalation in Microsoft Exchange Outlook Web Access (OWA)","id":"CVE-2018-0940","indexable":true,"kev":null,"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":"Information disclosure in Exchange Server","id":"CVE-2018-0941"},"packages":[],"prev":{"headline":"ChakraCore information disclosure vulnerability","id":"CVE-2018-0939"},"products":["Microsoft Exchange Outlook Web Access (OWA)"],"published":"2018-03-14","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":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-09-17","vendors":["Microsoft Corporation"]},"summary":"An attacker can exploit link rewriting in Outlook Web Access to elevate privileges within Microsoft Exchange Server.","url":"https://insights.sbomify.com/CVE-2018-0940/"}
