It can only be exploited from the same machine or local network, 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-2017-8537 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-2017-8537/ (Markdown: https://insights.sbomify.com/CVE-2017-8537/index.md)","id":"CVE-2017-8537","markdown":"https://insights.sbomify.com/CVE-2017-8537/index.md","name":"CVE-2017-8537","record":{"aliases":["GHSA-gc65-2679-m9fc"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Windows Malware Protection Engine","requires_auth":"none","summary":"Attackers can cause a denial of service in Microsoft Malware Protection Engine by submitting specially crafted files, affecting Windows and Exchange servers.","user_interaction":"required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":"endpoint_protection","vendor":"microsoft"},{"product":"exchange_server","vendor":"microsoft"},{"product":"forefront_endpoint_protection","vendor":"microsoft"},{"product":"security_essentials","vendor":"microsoft"},{"product":"system_center_endpoint_protection","vendor":"microsoft"},{"product":"windows_defender","vendor":"microsoft"},{"product":"windows_intune_endpoint_protection","vendor":"microsoft"}],"cvss":{"score":5.5,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-674","name":"Uncontrolled Recursion"},{"id":"CWE-476","name":"NULL Pointer Dereference"},{"id":"CWE-369","name":"Divide By Zero"},{"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 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, and Windows Server 2016, Microsoft Exchange Server 2013 and 2016, does not properly scan a specially crafted file leading to denial of service. aka \"Microsoft Malware Protection Engine Denial of Service Vulnerability\", a different vulnerability than CVE-2017-8535, CVE-2017-8536, CVE-2017-8539, and CVE-2017-8542.","ecosystems":[],"exploits":{"exploitdb":1,"first_seen":"2017-05-29","github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[{"date":"2017-05-29","kind":"exploitdb","ref":"42081","stars":null,"title":"Microsoft MsMpEng - Multiple Crashes While Scanning Malformed Files"}],"tier":"weaponised"},"has_fix":null,"headline":"Denial of service in Malware Protection Engine","id":"CVE-2017-8537","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"microsoft:exchange_server","products":["microsoft:exchange_server"],"type":"denial_of_service","year":"2017"},"n_packages":0,"n_references":4,"next":{"headline":"Memory corruption in Malware Protection Engine","id":"CVE-2017-8538"},"packages":[],"prev":{"headline":"Denial of service in Malware Protection Engine","id":"CVE-2017-8536"},"products":["Malware Protection Engine"],"published":"2017-05-26","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":7.8,"headline":"Memory corruption in Microsoft Malware Protection Engine","id":"CVE-2017-8558","kev_date_added":null,"published":"2017-06-29"},{"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"}],"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":"Attackers can cause a denial of service in Microsoft Malware Protection Engine by submitting specially crafted files, affecting Windows and Exchange servers.","url":"https://insights.sbomify.com/CVE-2017-8537/"}
