An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2018-0986 exists.\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-2018-0986/ (Markdown: https://insights.sbomify.com/CVE-2018-0986/index.md)","id":"CVE-2018-0986","markdown":"https://insights.sbomify.com/CVE-2018-0986/index.md","name":"CVE-2018-0986","record":{"aliases":["GHSA-v2gp-f824-rv7r"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Microsoft Malware Protection Engine","requires_auth":"none","summary":"Remote attackers can execute arbitrary code by sending a specially crafted file to systems using the Microsoft Malware Protection Engine.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":"exchange_server","vendor":"microsoft"},{"product":"forefront_endpoint_protection_2010","vendor":"microsoft"},{"product":"intune_endpoint_protection","vendor":"microsoft"},{"product":"security_essentials","vendor":"microsoft"},{"product":"system_center_endpoint_protection","vendor":"microsoft"},{"product":"windows_defender","vendor":"microsoft"}],"cvss":{"score":8.8,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"}],"description":"A remote code execution vulnerability exists when the Microsoft Malware Protection Engine does not properly scan a specially crafted file, leading to memory corruption, aka \"Microsoft Malware Protection Engine Remote Code Execution Vulnerability.\" This affects Windows Defender, Windows Intune Endpoint Protection, Microsoft Security Essentials, Microsoft System Center Endpoint Protection, Microsoft Exchange Server, Microsoft System Center, Microsoft Forefront Endpoint Protection.","ecosystems":[],"exploits":{"exploitdb":1,"first_seen":"2018-04-05","github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[{"date":"2018-04-05","kind":"exploitdb","ref":"44402","stars":null,"title":"Microsoft Windows Defender - 'mpengine.dll' Memory Corruption"}],"tier":"weaponised"},"has_fix":null,"headline":"Memory corruption in Microsoft Exchange Server","id":"CVE-2018-0986","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"microsoft:exchange_server","products":["microsoft:exchange_server"],"type":"memory_corruption","year":"2018"},"n_packages":0,"n_references":4,"next":{"headline":"Information disclosure in Internet Explorer 10","id":"CVE-2018-0987"},"packages":[],"prev":{"headline":"Memory corruption in Windows Storage Services","id":"CVE-2018-0983"},"products":["Microsoft Exchange Server","Microsoft Forefront Endpoint Protection","Microsoft Security Essentials","Microsoft System Center","Microsoft System Center Endpoint Protection","Windows Defender","Windows Intune Endpoint Protection"],"published":"2018-04-04","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":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"},{"class":"attribution","licence":"GPL-2.0-or-later","name":"Exploit-DB"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-05","vendors":["Microsoft"]},"summary":"Remote attackers can execute arbitrary code by sending a specially crafted file to systems using the Microsoft Malware Protection Engine.","url":"https://insights.sbomify.com/CVE-2018-0986/"}
