An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2021-42783 and fix it if it is affected.\n\nWhat it is: CVE-2021-42783 is a critical missing authorization 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-2021-42783 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-2021-42783/ (Markdown: https://insights.sbomify.com/CVE-2021-42783/index.md)","id":"CVE-2021-42783","markdown":"https://insights.sbomify.com/CVE-2021-42783/index.md","name":"CVE-2021-42783","record":{"aliases":["GHSA-crhj-frp3-x49w"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["privilege_escalation","code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"D-Link router firmware","requires_auth":"none","summary":"Unauthenticated attackers can execute administrative actions on D-Link DWR-932C E1 routers via the debug_post_set.cgi endpoint.","user_interaction":"not_required","vuln_class":"missing_authorization"},"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-306","name":"Missing Authentication for Critical Functionality"}],"description":"Missing Authentication for Critical Function vulnerability in debug_post_set.cgi of D-Link DWR-932C E1 firmware allows an unauthenticated attacker to execute administrative actions.","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":"Missing Authentication in debug_post_set.cgi in D-Link DWR-932C E1 Firmware 1.0.0.4","id":"CVE-2021-42783","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"missing_authorization","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"OS Command Injection in debug_fcgi in D-Link DWR-932C E1 Firmware 1.0.0.4","id":"CVE-2021-42784"},"packages":[],"prev":{"headline":"Stack buffer overflow issues were found in Opensc before version 0.22.0 in various places that could potentially crash programs using the library.","id":"CVE-2021-42782"},"products":["DWR-932C E1"],"published":"2021-11-23","related":[{"cvss_score":9.8,"headline":"OS Command Injection in debug_fcgi in D-Link DWR-932C E1 Firmware 1.0.0.4","id":"CVE-2021-42784","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":"Unauthenticated attackers can execute administrative actions on D-Link DWR-932C E1 routers via the debug_post_set.cgi endpoint.","url":"https://insights.sbomify.com/CVE-2021-42783/"}
