It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2017-8558 exists.\n\nAffected product: Microsoft Malware Protection Engine. 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-2017-8558/ (Markdown: https://insights.sbomify.com/CVE-2017-8558/index.md)","id":"CVE-2017-8558","markdown":"https://insights.sbomify.com/CVE-2017-8558/index.md","name":"CVE-2017-8558","record":{"aliases":["GHSA-ghvf-8cx5-ch3h"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Windows Defender","requires_auth":"low_privilege","summary":"Remote attackers can execute arbitrary code by sending a specially crafted file to the Microsoft Malware Protection Engine.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":"endpoint_protection","vendor":"microsoft"},{"product":"forefront_endpoint_protection","vendor":"microsoft"},{"product":"security_essentials","vendor":"microsoft"},{"product":"windows_defender","vendor":"microsoft"},{"product":"windows_intune_endpoint_protection","vendor":"microsoft"}],"cvss":{"score":7.8,"severity":"high","source":"nvd","vector":"CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-119","name":"Improper Restriction of Operations within the Bounds of a Memory Buffer"}],"description":"The Microsoft Malware Protection Engine running on Microsoft Forefront and Microsoft Defender on 32-bit versions of Microsoft Windows Server 2008 SP2 and R2 SP1, Windows 7 SP1, Windows 8.1, Windows Server 2012 Gold and R2, Windows RT 8.1, Windows 10 Gold, 1511, 1607, and 1703 does not properly scan a specially crafted file leading to memory corruption. aka \"Microsoft Malware Protection Engine Remote Code Execution Vulnerability\".","ecosystems":[],"exploits":{"exploitdb":1,"first_seen":"2017-06-27","github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[{"date":"2017-06-27","kind":"exploitdb","ref":"42264","stars":null,"title":"Microsoft MsMpEng - mpengine x86 Emulator Heap Corruption in VFS API"}],"tier":"weaponised"},"has_fix":null,"headline":"Memory corruption in Microsoft Malware Protection Engine","id":"CVE-2017-8558","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2017"},"n_packages":0,"n_references":5,"next":{"headline":"Cross-site scripting in Microsoft Exchange Server 2010 SP3, Exchange Server 2013 SP3, Exchange Server 2013 CU16, and Exchange Server 2016 CU5.","id":"CVE-2017-8559"},"packages":[],"prev":{"headline":"XML external entity in Windows Server 2008 SP2 and R2 SP1, Windows 7 SP1, Windows 8.1, Windows Server 2012 Gold and R2, Windows RT 8.1, Windows 10 Gold, 1511, 1607, 1703, and Windows Server 2016","id":"CVE-2017-8557"},"products":["Microsoft Malware Protection Engine"],"published":"2017-06-29","related":[{"cvss_score":7.8,"headline":"Microsoft Malware Protection Engine Improper Restriction of Operations","id":"CVE-2017-8540","kev_date_added":"2022-03-03","published":"2017-05-26"},{"cvss_score":7.8,"headline":"Microsoft Defender Elevation of Privilege Vulnerability","id":"CVE-2021-24092","kev_date_added":null,"published":"2021-02-25"},{"cvss_score":5.5,"headline":"Denial of service in Malware Protection Engine","id":"CVE-2017-8535","kev_date_added":null,"published":"2017-05-26"},{"cvss_score":5.5,"headline":"Denial of service in Malware Protection Engine","id":"CVE-2017-8536","kev_date_added":null,"published":"2017-05-26"},{"cvss_score":5.5,"headline":"Denial of service in Malware Protection Engine","id":"CVE-2017-8537","kev_date_added":null,"published":"2017-05-26"}],"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 Corporation"]},"summary":"Remote attackers can execute arbitrary code by sending a specially crafted file to the Microsoft Malware Protection Engine.","url":"https://insights.sbomify.com/CVE-2017-8558/"}
