An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2021-42784 and fix it if it is affected.\n\nWhat it is: CVE-2021-42784 is a critical command injection vulnerability in D-Link DWR-932C E1, published on 23 Nov 2021. 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-2021-42784 in the wild and no public exploit code.\n\nAffected product: D-Link DWR-932C E1. 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-2021-42784/ (Markdown: https://insights.sbomify.com/CVE-2021-42784/index.md)","id":"CVE-2021-42784","markdown":"https://insights.sbomify.com/CVE-2021-42784/index.md","name":"CVE-2021-42784","record":{"aliases":["GHSA-23jf-wqc3-q3jr"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"D-Link router firmware","requires_auth":"none","summary":"Remote attackers can execute arbitrary OS commands on D-Link DWR-932C E1 routers via crafted HTTP requests to the debug_fcgi component.","user_interaction":"not_required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GovTech CSG","cpe":[{"product":"dwr-932c_e1_firmware","vendor":"dlink"}],"cvss":{"score":9.8,"severity":"critical","source":"nvd","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":"OS Command Injection vulnerability in debug_fcgi of D-Link DWR-932C E1 firmware allows a remote attacker to perform command injection via a crafted HTTP request.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"OS Command Injection in debug_fcgi in D-Link DWR-932C E1 Firmware 1.0.0.4","id":"CVE-2021-42784","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"command_injection","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Buffer Overflow in tvnviewer.exe via Crafted Packet in TightVNC Viewer 2.8.59","id":"CVE-2021-42785"},"packages":[],"prev":{"headline":"Missing Authentication in debug_post_set.cgi in D-Link DWR-932C E1 Firmware 1.0.0.4","id":"CVE-2021-42783"},"products":["DWR-932C E1"],"published":"2021-11-23","related":[{"cvss_score":9.8,"headline":"Missing Authentication in debug_post_set.cgi in D-Link DWR-932C E1 Firmware 1.0.0.4","id":"CVE-2021-42783","kev_date_added":null,"published":"2021-11-23"}],"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":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-04","vendors":["D-Link"]},"summary":"Remote attackers can execute arbitrary OS commands on D-Link DWR-932C E1 routers via crafted HTTP requests to the debug_fcgi component.","url":"https://insights.sbomify.com/CVE-2021-42784/"}
