Any signed-in user can exploit it over the network, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2025-4731 and fix it if it is affected.\n\nWhat it is: CVE-2025-4731 is a high-severity memory corruption vulnerability in Totolink A3002r Firmware, published on 16 May 2025. Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2025-4731 in the wild and no public exploit code.\n\nAffected product: Totolink A3002r Firmware. 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-2025-4731/ (Markdown: https://insights.sbomify.com/CVE-2025-4731/index.md)","id":"CVE-2025-4731","markdown":"https://insights.sbomify.com/CVE-2025-4731/index.md","name":"CVE-2025-4731","record":{"aliases":["GHSA-7pjr-pgpp-7jxm"],"analysis":{"component_type":"network_device","fix_type":"no_fix_stated","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"TOTOLINK router","requires_auth":"low_privilege","summary":"Remote attackers can trigger a buffer overflow in TOTOLINK routers via crafted HTTP POST requests, potentially leading to code execution or service disruption.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulDB","cpe":[{"product":"a3002r_firmware","vendor":"totolink"},{"product":"a3002ru_firmware","vendor":"totolink"}],"cvss":{"score":8.7,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-120","name":"Buffer Copy without Checking Size of Input"},{"id":"CWE-119","name":"Improper Restriction of Operations within the Bounds of a Memory Buffer"}],"description":"A vulnerability classified as critical has been found in TOTOLINK A3002R and A3002RU 3.0.0-B20230809.1615.
