An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: Yes. Attackers have exploited CVE-2020-0796 in the wild since at least 10 Feb 2022, including in ransomware campaigns.\n\nAffected product: Microsoft Windows 10 Version 1903 for 32-bit Systems. 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-2020-0796/ (Markdown: https://insights.sbomify.com/CVE-2020-0796/index.md)","id":"CVE-2020-0796","markdown":"https://insights.sbomify.com/CVE-2020-0796/index.md","name":"CVE-2020-0796","record":{"aliases":["GHSA-vh23-87v3-h8c6"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Windows SMBv3","requires_auth":"none","summary":"Remote attackers can execute arbitrary code via crafted SMBv3 requests, affecting Windows 10 and Server systems.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":"windows_10_1903","vendor":"microsoft"},{"product":"windows_10_1909","vendor":"microsoft"},{"product":"windows_server_1903","vendor":"microsoft"},{"product":"windows_server_1909","vendor":"microsoft"}],"cvss":{"score":10,"severity":"critical","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-119","name":"Improper Restriction of Operations within the Bounds of a Memory Buffer"}],"description":"A remote code execution vulnerability exists in the way that the Microsoft Server Message Block 3.1.1 (SMBv3) protocol handles certain requests, aka 'Windows SMBv3 Client/Server Remote Code Execution Vulnerability'.","ecosystems":[],"exploits":{"exploitdb":3,"first_seen":"2019-11-19","github_poc":86,"max_poc_stars":1358,"metasploit":2,"nuclei":1,"refs":[{"date":"2020-03-30T11:42:56Z","kind":"github_poc","ref":"https://github.com/danigargu/CVE-2020-0796","stars":1358,"title":"CVE-2020-0796 - Windows SMBv3 LPE exploit #SMBGhost"},{"date":"2020-03-11T15:21:27Z","kind":"github_poc","ref":"https://github.com/ly4k/SMBGhost","stars":723,"title":"Scanner for CVE-2020-0796 - SMBv3 RCE"},{"date":"2020-04-20T14:35:48Z","kind":"github_poc","ref":"https://github.com/jamf/CVE-2020-0796-RCE-POC","stars":569,"title":"CVE-2020-0796 Remote Code Execution POC"},{"date":"2020-06-10T16:44:39Z","kind":"github_poc","ref":"https://github.com/Barriuso/SMBGhost_AutomateExploitation","stars":360,"title":"SMBGhost (CVE-2020-0796) Automate Exploitation and Detection"},{"date":"2020-03-12T18:34:40Z","kind":"github_poc","ref":"https://github.com/eerykitty/CVE-2020-0796-PoC","stars":332,"title":"PoC for triggering buffer overflow via CVE-2020-0796"},{"date":"2020-03-30T16:06:50Z","kind":"github_poc","ref":"https://github.com/jamf/CVE-2020-0796-LPE-POC","stars":244,"title":"CVE-2020-0796 Local Privilege Escalation POC"},{"date":"2020-04-06T15:16:10Z","kind":"github_poc","ref":"https://github.com/Rvn0xsy/CVE_2020_0796_CNA","stars":74,"title":"Cobalt Strike AggressorScripts CVE-2020-0796"},{"date":"2020-09-17T01:48:37Z","kind":"github_poc","ref":"https://github.com/rsmudge/CVE-2020-0796-BOF","stars":70,"title":null}],"tier":"exploited"},"has_fix":null,"headline":"Microsoft SMBv3 Remote Code Execution","id":"CVE-2020-0796","indexable":true,"kev":{"dateAdded":"2022-02-10","dueDate":"2022-08-10","knownRansomwareCampaignUse":"Known","product":"SMBv3","requiredAction":"Apply updates per vendor instructions.","vendorProject":"Microsoft","vulnerabilityName":"Microsoft SMBv3 Remote Code Execution Vulnerability"},"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2020"},"n_packages":0,"n_references":7,"next":{"headline":"Privilege escalation in Windows","id":"CVE-2020-0797"},"packages":[],"prev":{"headline":"Cross-site scripting in Microsoft Business Productivity Servers","id":"CVE-2020-0795"},"products":["Windows 10 Version 1903 for 32-bit Systems","Windows 10 Version 1903 for ARM64-based Systems","Windows 10 Version 1903 for x64-based Systems","Windows 10 Version 1909 for 32-bit Systems","Windows 10 Version 1909 for ARM64-based Systems","Windows 10 Version 1909 for x64-based Systems","Windows Server, version 1903 (Server Core installation)","Windows Server, version 1909 (Server Core installation)"],"published":"2020-03-12","related":[],"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":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"},{"class":"open","licence":"CC0","name":"PoC-in-GitHub"}],"ssvc":{"automatable":"yes","exploitation":"active","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-10-01","vendors":["Microsoft"]},"summary":"Remote attackers can execute arbitrary code via crafted SMBv3 requests, affecting Windows 10 and Server systems.","url":"https://insights.sbomify.com/CVE-2020-0796/"}
