Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2019-18931 in the wild and no public exploit code.\n\nAffected product: n/a. 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-2019-18931/ (Markdown: https://insights.sbomify.com/CVE-2019-18931/index.md)","id":"CVE-2019-18931","markdown":"https://insights.sbomify.com/CVE-2019-18931/index.md","name":"CVE-2019-18931","record":{"aliases":["GHSA-3f5p-w7xp-rch2"],"analysis":{"component_type":"iot_embedded","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Western Digital NAS","requires_auth":"low_privilege","summary":"Attackers can execute arbitrary code on Western Digital My Cloud EX2 Ultra devices by exploiting a buffer overflow in firmware via crafted web requests.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"my_cloud_ex2_ultra_firmware","vendor":"western_digital"}],"cvss":{"score":8.8,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-120","name":"Buffer Copy without Checking Size of Input"}],"description":"Western Digital My Cloud EX2 Ultra firmware 2.31.195 allows a Buffer Overflow with Extended Instruction Pointer (EIP) control via crafted GET/POST parameters.","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":"Memory corruption in n/a","id":"CVE-2019-18931","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2019"},"n_packages":0,"n_references":2,"next":{"headline":"Race condition in n/a","id":"CVE-2019-18932"},"packages":[],"prev":{"headline":"Memory corruption in n/a","id":"CVE-2019-18930"},"products":["n/a"],"published":"2019-11-13","related":[{"cvss_score":8.8,"headline":"Memory corruption in n/a","id":"CVE-2019-18929","kev_date_added":null,"published":"2019-11-13"},{"cvss_score":8.8,"headline":"Memory corruption in n/a","id":"CVE-2019-18930","kev_date_added":null,"published":"2019-11-13"}],"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)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-05","vendors":["n/a"]},"summary":"Attackers can execute arbitrary code on Western Digital My Cloud EX2 Ultra devices by exploiting a buffer overflow in firmware via crafted web requests.","url":"https://insights.sbomify.com/CVE-2019-18931/"}
