It can only be exploited from the same machine or local network, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2021-3707 and fix it if it is affected.\n\nWhat it is: CVE-2021-3707 is a medium-severity missing authorization vulnerability in D-Link DSL-2750U, published on 16 Aug 2021. It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-3707 in the wild and no public exploit code.\n\nAffected product: D-Link DSL-2750U. 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-2021-3707/ (Markdown: https://insights.sbomify.com/CVE-2021-3707/index.md)","id":"CVE-2021-3707","markdown":"https://insights.sbomify.com/CVE-2021-3707/index.md","name":"CVE-2021-3707","record":{"aliases":["GHSA-q2w4-9m66-g5ff"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"D-Link router","requires_auth":"low_privilege","summary":"Unauthenticated local attackers can modify router configuration and execute OS commands on D-Link DSL-2750U devices.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jpcert","cpe":[{"product":"dsl-2750u_firmware","vendor":"dlink"}],"cvss":{"score":5.5,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-15","name":"External Control of System or Configuration Setting"}],"description":"D-Link router DSL-2750U with firmware vME1.16 or prior versions is vulnerable to unauthorized configuration modification.
