An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2018-8531 in the wild and no public exploit code.\n\nAffected product: Microsoft Azure IoT Edge. 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-2018-8531/ (Markdown: https://insights.sbomify.com/CVE-2018-8531/index.md)","id":"CVE-2018-8531","markdown":"https://insights.sbomify.com/CVE-2018-8531/index.md","name":"CVE-2018-8531","record":{"aliases":["GHSA-x6h5-845f-rv5f"],"analysis":{"component_type":"iot_embedded","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Azure IoT Edge","requires_auth":"none","summary":"Remote attackers can execute arbitrary code via memory corruption in the Azure IoT Hub Device Client SDK using MQTT.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":"azure_internet_of_things_edge","vendor":"microsoft"},{"product":"csharp_software_development_kit","vendor":"microsoft"}],"cvss":{"score":8.8,"severity":"high","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"}],"description":"A remote code execution vulnerability exists in the way that Azure IoT Hub Device Client SDK using MQTT protocol accesses objects in memory, aka \"Azure IoT Device Client SDK Memory Corruption Vulnerability.\" This affects Hub Device Client SDK, Azure IoT Edge.","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 Azure IoT Edge","id":"CVE-2018-8531","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2018"},"n_packages":0,"n_references":2,"next":{"headline":"XML external entity in SQL Server Management Studio 17.9","id":"CVE-2018-8532"},"packages":[],"prev":{"headline":"Security feature bypass in Microsoft Edge","id":"CVE-2018-8530"},"products":["Azure IoT Edge","Hub Device Client SDK"],"published":"2018-10-10","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":"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":["Microsoft"]},"summary":"Remote attackers can execute arbitrary code via memory corruption in the Azure IoT Hub Device Client SDK using MQTT.","url":"https://insights.sbomify.com/CVE-2018-8531/"}
