An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2025-5621 exists.\n\nAffected product: Dlink Dir-816 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-2025-5621/ (Markdown: https://insights.sbomify.com/CVE-2025-5621/index.md)","id":"CVE-2025-5621","markdown":"https://insights.sbomify.com/CVE-2025-5621/index.md","name":"CVE-2025-5621","record":{"aliases":["GHSA-j6wp-hqmg-gx4g"],"analysis":{"component_type":"network_device","fix_type":"end_of_life","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"D-Link router","requires_auth":"none","summary":"Remote attackers can execute arbitrary OS commands on unsupported D-Link DIR-816 routers via the qosClassifier interface.","user_interaction":"not_required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulDB","cpe":[{"product":"dir-816_firmware","vendor":"dlink"}],"cvss":{"score":6.9,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-78","name":"Improper Neutralization of Special Elements used in an OS Command"},{"id":"CWE-77","name":"Improper Neutralization of Special Elements used in a Command"}],"description":"A vulnerability has been found in D-Link DIR-816 1.10CNB05 and classified as critical.
