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-2017-7964 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-2017-7964/ (Markdown: https://insights.sbomify.com/CVE-2017-7964/index.md)","id":"CVE-2017-7964","markdown":"https://insights.sbomify.com/CVE-2017-7964/index.md","name":"CVE-2017-7964","record":{"aliases":["GHSA-2wc3-9w3j-8phw"],"analysis":{"component_type":"network_device","fix_type":"configuration_change","impacts":["privilege_escalation","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"Zyxel wireless extender","requires_auth":"none","summary":"Remote attackers can exploit default TELNET credentials to gain root access and modify DNS settings, enabling hijacking attacks on Zyxel WRE6505 devices.","user_interaction":"not_required","vuln_class":"hardcoded_credentials"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"wre6505_firmware","vendor":"zyxel"}],"cvss":{"score":10,"severity":"critical","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-1188","name":"Initialization of a Resource with an Insecure Default"}],"description":"Zyxel WRE6505 devices have a default TELNET password of 1234 for the root and admin accounts, which makes it easier for remote attackers to conduct DNS hijacking attacks by reconfiguring the built-in dnshijacker process.","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":"Hardcoded credentials in n/a","id":"CVE-2017-7964","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"hardcoded_credentials","year":"2017"},"n_packages":0,"n_references":1,"next":{"headline":"Memory corruption in SoMachine HVAC Programming Software","id":"CVE-2017-7965"},"packages":[],"prev":{"headline":"Denial of service in n/a","id":"CVE-2017-7963"},"products":["n/a"],"published":"2017-04-19","related":[{"cvss_score":8.8,"headline":"Command injection in WRE6505 v2 firmware","id":"CVE-2026-7256","kev_date_added":null,"published":"2026-05-12"},{"cvss_score":6.5,"headline":"Auth bypass in WRE6505 v2 firmware","id":"CVE-2026-7255","kev_date_added":null,"published":"2026-05-12"},{"cvss_score":4.5,"headline":"Cross-site scripting in WRE6505 v2 firmware","id":"CVE-2026-6058","kev_date_added":null,"published":"2026-04-21"},{"cvss_score":4.4,"headline":"Information disclosure in WRE6505 v2 firmware","id":"CVE-2026-7257","kev_date_added":null,"published":"2026-05-12"}],"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":"2024-09-16","vendors":["n/a"]},"summary":"Remote attackers can exploit default TELNET credentials to gain root access and modify DNS settings, enabling hijacking attacks on Zyxel WRE6505 devices.","url":"https://insights.sbomify.com/CVE-2017-7964/"}
