An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: Yes. Attackers have exploited CVE-2019-16920 in the wild since at least 25 Mar 2022.\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-2019-16920/ (Markdown: https://insights.sbomify.com/CVE-2019-16920/index.md)","id":"CVE-2019-16920","markdown":"https://insights.sbomify.com/CVE-2019-16920/index.md","name":"CVE-2019-16920","record":{"aliases":["GHSA-5p5j-jvxx-68mp"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"D-Link router","requires_auth":"none","summary":"Unauthenticated attackers can execute arbitrary commands via the PingTest interface, leading to full system compromise on affected D-Link routers.","user_interaction":"not_required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"dap-1533_firmware","vendor":"dlink"},{"product":"dhp-1565_firmware","vendor":"dlink"},{"product":"dir-615_firmware","vendor":"dlink"},{"product":"dir-652_firmware","vendor":"dlink"},{"product":"dir-655_firmware","vendor":"dlink"},{"product":"dir-825_firmware","vendor":"dlink"},{"product":"dir-835_firmware","vendor":"dlink"},{"product":"dir-855l_firmware","vendor":"dlink"},{"product":"dir-862l_firmware","vendor":"dlink"},{"product":"dir-866l_firmware","vendor":"dlink"}],"cvss":{"score":9.8,"severity":"critical","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-78","name":"Improper Neutralization of Special Elements used in an OS Command"}],"description":"Unauthenticated remote code execution occurs in D-Link products such as DIR-655C, DIR-866L, DIR-652, and DHP-1565.
