Any signed-in user can exploit it over the network, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2018-3875 and fix it if it is affected.\n\nWhat it is: CVE-2018-3875 is a critical memory corruption vulnerability in Samsung SmartThings Hub STH-ETH-250, published on 10 Sep 2018. Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2018-3875 in the wild and no public exploit code.\n\nAffected product: Samsung SmartThings Hub STH-ETH-250. 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-2018-3875/ (Markdown: https://insights.sbomify.com/CVE-2018-3875/index.md)","id":"CVE-2018-3875","markdown":"https://insights.sbomify.com/CVE-2018-3875/index.md","name":"CVE-2018-3875","record":{"aliases":["GHSA-98wj-w9r7-fcxv"],"analysis":{"component_type":"iot_embedded","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"SmartThings Hub","requires_auth":"low_privilege","summary":"An attacker can execute arbitrary code on Samsung SmartThings Hub devices by sending a maliciously crafted JSON payload with an overly long session token.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"talos","cpe":[{"product":"sth-eth-250_firmware","vendor":"samsung"}],"cvss":{"score":9.9,"severity":"critical","source":"cna","vector":"CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:C/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":"An exploitable buffer overflow vulnerability exists in the credentials handler of video-core's HTTP server of Samsung SmartThings Hub STH-ETH-250-Firmware version 0.20.17.
