An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: Yes. Attackers have exploited CVE-2019-17621 in the wild since at least 29 Jun 2023.\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-2019-17621/ (Markdown: https://insights.sbomify.com/CVE-2019-17621/index.md)","id":"CVE-2019-17621","markdown":"https://insights.sbomify.com/CVE-2019-17621/index.md","name":"CVE-2019-17621","record":{"aliases":["GHSA-4cjx-47hq-7hc2"],"analysis":{"component_type":"network_device","fix_type":"no_fix_stated","impacts":["code_execution","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"Wi-Fi router","requires_auth":"none","summary":"Unauthenticated remote attackers can execute system commands as root on D-Link DIR-859 routers via the UPnP service.","user_interaction":"not_required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"dir-818lx_firmware","vendor":"dlink"},{"product":"dir-822_firmware","vendor":"dlink"},{"product":"dir-823_firmware","vendor":"dlink"},{"product":"dir-859_firmware","vendor":"dlink"},{"product":"dir-865l_firmware","vendor":"dlink"},{"product":"dir-868l_firmware","vendor":"dlink"},{"product":"dir-869_firmware","vendor":"dlink"},{"product":"dir-880l_firmware","vendor":"dlink"},{"product":"dir-885l_firmware","vendor":"dlink"},{"product":"dir-885r_firmware","vendor":"dlink"},{"product":"dir-890l_firmware","vendor":"dlink"},{"product":"dir-890r_firmware","vendor":"dlink"},{"product":"dir-895l_firmware","vendor":"dlink"},{"product":"dir-895r_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":"The UPnP endpoint URL /gena.cgi in the D-Link DIR-859 Wi-Fi router 1.05 and 1.06B01 Beta01 allows an Unauthenticated remote attacker to execute system commands as root, by sending a specially crafted HTTP SUBSCRIBE request to the UPnP service when connecting to the local network.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2019-12-24","github_poc":1,"max_poc_stars":3,"metasploit":1,"nuclei":0,"refs":[{"date":"2022-07-20T09:39:36Z","kind":"github_poc","ref":"https://github.com/Squirre17/CVE-2019-17621","stars":3,"title":"CVE-2019-17621 DLink_RCE"},{"date":"2019-12-24","kind":"metasploit","ref":"exploit/linux/upnp/dlink_dir859_subscribe_exec","stars":null,"title":"D-Link DIR-859 Unauthenticated Remote Command Execution"}],"tier":"exploited"},"has_fix":null,"headline":"D-Link DIR-859 Router Command Execution","id":"CVE-2019-17621","indexable":true,"kev":{"dateAdded":"2023-06-29","dueDate":"2023-07-20","knownRansomwareCampaignUse":"Unknown","product":"DIR-859 Router","requiredAction":"Apply updates per vendor instructions or discontinue use of the product if updates are unavailable.","vendorProject":"D-Link","vulnerabilityName":"D-Link DIR-859 Router Command Execution Vulnerability"},"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"command_injection","year":"2019"},"n_packages":0,"n_references":7,"next":{"headline":"Memory corruption in n/a","id":"CVE-2019-17624"},"packages":[],"prev":{"headline":"Code injection in n/a","id":"CVE-2019-17613"},"products":["n/a"],"published":"2019-12-30","related":[{"cvss_score":7.5,"headline":"Auth bypass in n/a","id":"CVE-2019-20213","kev_date_added":null,"published":"2020-01-02"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"open","licence":"CC0 1.0","name":"CISA KEV"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"},{"class":"attribution","licence":"BSD-3-Clause","name":"Metasploit"},{"class":"open","licence":"CC0","name":"PoC-in-GitHub"}],"ssvc":{"automatable":"yes","exploitation":"active","technical_impact":"total"},"state":"PUBLISHED","updated":"2025-10-21","vendors":["n/a"]},"summary":"Unauthenticated remote attackers can execute system commands as root on D-Link DIR-859 routers via the UPnP service.","url":"https://insights.sbomify.com/CVE-2019-17621/"}
