An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-29294 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-2021-29294/ (Markdown: https://insights.sbomify.com/CVE-2021-29294/index.md)","id":"CVE-2021-29294","markdown":"https://insights.sbomify.com/CVE-2021-29294/index.md","name":"CVE-2021-29294","record":{"aliases":["GHSA-4gpq-jpqc-j6v2"],"analysis":{"component_type":"network_device","fix_type":"end_of_life","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"D-Link DSL-2740R","requires_auth":"none","summary":"A remote attacker can cause a denial of service on the D-Link DSL-2740R router via a crafted POST request, but the device is end-of-life and will not be patched.","user_interaction":"not_required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"dsl-2740r_firmware","vendor":"dlink"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-476","name":"NULL Pointer Dereference"}],"description":"Null Pointer Dereference vulnerability exists in D-Link DSL-2740R UK_1.01, which could let a remove malicious user cause a denial of service via the send_hnap_unauthorized function.
