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-2017-9478 in the wild and no public exploit code.\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-2017-9478/ (Markdown: https://insights.sbomify.com/CVE-2017-9478/index.md)","id":"CVE-2017-9478","markdown":"https://insights.sbomify.com/CVE-2017-9478/index.md","name":"CVE-2017-9478","record":{"aliases":["GHSA-wcmp-jh6v-8592"],"analysis":{"component_type":"network_device","fix_type":"no_fix_stated","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Cisco Cable Modem","requires_auth":"none","summary":"Remote attackers can discover hidden Home Security Wi-Fi networks by exploiting MAC address offsets in Cisco DPC3939 firmware.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"dpc3939_firmware","vendor":"cisco"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","version":"3.0"},"cwes":[{"id":"CWE-200","name":"Exposure of Sensitive Information to an Unauthorized Actor"}],"description":"The Comcast firmware on Cisco DPC3939 (firmware version dpc3939-P20-18-v303r20421733-160420a-CMCST) and DPC3939 (firmware version dpc3939-P20-18-v303r20421746-170221a-CMCST) devices sets the CM MAC address to a value with a two-byte offset from the MTA/VoIP MAC address, which indirectly allows remote attackers to discover hidden Home Security Wi-Fi networks by leveraging the embedding of the MTA/VoIP MAC address into the DNS hostname.","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":"Information disclosure in n/a","id":"CVE-2017-9478","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"information_disclosure","year":"2017"},"n_packages":0,"n_references":1,"next":{"headline":"Command injection in n/a","id":"CVE-2017-9479"},"packages":[],"prev":{"headline":"Information disclosure in n/a","id":"CVE-2017-9477"},"products":["n/a"],"published":"2017-07-31","related":[{"cvss_score":9.8,"headline":"Command injection in n/a","id":"CVE-2017-9479","kev_date_added":null,"published":"2017-07-31"},{"cvss_score":9.8,"headline":"Auth bypass in n/a","id":"CVE-2017-9482","kev_date_added":null,"published":"2017-07-31"},{"cvss_score":9.8,"headline":"Command injection in n/a","id":"CVE-2017-9483","kev_date_added":null,"published":"2017-07-31"},{"cvss_score":9.8,"headline":"Other in n/a","id":"CVE-2017-9521","kev_date_added":null,"published":"2017-07-31"},{"cvss_score":8.8,"headline":"Hardcoded credentials in n/a","id":"CVE-2017-9488","kev_date_added":null,"published":"2017-07-31"},{"cvss_score":7.5,"headline":"Missing authorization in n/a","id":"CVE-2017-9481","kev_date_added":null,"published":"2017-07-31"}],"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":"2024-08-05","vendors":["n/a"]},"summary":"Remote attackers can discover hidden Home Security Wi-Fi networks by exploiting MAC address offsets in Cisco DPC3939 firmware.","url":"https://insights.sbomify.com/CVE-2017-9478/"}
