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-2024-21876 in the wild and no public exploit code.\n\nAffected product: Enphase IQ Gateway. 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-2024-21876/ (Markdown: https://insights.sbomify.com/CVE-2024-21876/index.md)","id":"CVE-2024-21876","markdown":"https://insights.sbomify.com/CVE-2024-21876/index.md","name":"CVE-2024-21876","record":{"aliases":["GHSA-wwmm-864r-f54x"],"analysis":{"component_type":"iot_embedded","fix_type":"upgrade","impacts":["data_read","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"Enphase IQ Gateway","requires_auth":"none","summary":"Unauthenticated attackers can access or create arbitrary files via path traversal in Enphase IQ Gateway, requiring an upgrade to secure the device.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"DIVD","cpe":[{"product":"iq_gateway_firmware","vendor":"enphase"}],"cvss":{"score":9.3,"severity":"critical","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N/S:N/AU:Y/V:D/RE:H","version":"4.0"},"cwes":[{"id":"CWE-22","name":"Improper Limitation of a Pathname to a Restricted Directory"}],"description":"Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') vulnerability via a URL parameter in Enphase IQ Gateway (formerly known as Envoy) allows an unautheticated attacker to access or create arbitratry files.This issue affects Envoy: from 4.x to 8.x and \u003c 8.2.4225.","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":"Unauthenticated Path Traversal via URL Parameter in Enphase IQ Gateway version \u003c 8.2.4225","id":"CVE-2024-21876","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"path_traversal","year":"2024"},"n_packages":0,"n_references":3,"next":{"headline":"Insecure File Generation Based on User Input in Enphase IQ Gateway version 4.x to 8.x and \u003c 8.2.4225","id":"CVE-2024-21877"},"packages":[],"prev":{"headline":"DoS attack when broadcasting billboard messages","id":"CVE-2024-21875"},"products":["IQ Gateway"],"published":"2024-08-10","related":[{"cvss_score":8.7,"headline":"Command injection in Envoy","id":"CVE-2024-21879","kev_date_added":null,"published":"2024-08-10"},{"cvss_score":8.6,"headline":"Insecure File Generation Based on User Input in Enphase IQ Gateway version 4.x to 8.x and \u003c 8.2.4225","id":"CVE-2024-21877","kev_date_added":null,"published":"2024-08-10"},{"cvss_score":8.6,"headline":"Command injection in Envoy","id":"CVE-2024-21880","kev_date_added":null,"published":"2024-08-10"},{"cvss_score":7.1,"headline":"Command injection in Envoy","id":"CVE-2024-21878","kev_date_added":null,"published":"2024-08-10"}],"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":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2025-03-11","vendors":["Enphase"]},"summary":"Unauthenticated attackers can access or create arbitrary files via path traversal in Enphase IQ Gateway, requiring an upgrade to secure the device.","url":"https://insights.sbomify.com/CVE-2024-21876/"}
