An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2017-16953 exists.\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-2017-16953/ (Markdown: https://insights.sbomify.com/CVE-2017-16953/index.md)","id":"CVE-2017-16953","markdown":"https://insights.sbomify.com/CVE-2017-16953/index.md","name":"CVE-2017-16953","record":{"aliases":["GHSA-96hm-5phv-9888"],"analysis":{"component_type":"network_device","fix_type":"no_fix_stated","impacts":["data_modify","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"ZTE DSL modem","requires_auth":"none","summary":"Remote attackers can modify PPPoE configurations on ZTE ZXDSL 831CII devices without authentication via unauthenticated GET requests.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"zxdsl_831cii_firmware","vendor":"zte"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N","version":"3.0"},"cwes":[{"id":"CWE-287","name":"Improper Authentication"}],"description":"connoppp.cgi on ZTE ZXDSL 831CII devices does not require HTTP Basic Authentication, which allows remote attackers to modify the PPPoE configuration or set up a malicious configuration via a GET request.","ecosystems":[],"exploits":{"exploitdb":1,"first_seen":"2017-11-27","github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[{"date":"2017-11-27","kind":"exploitdb","ref":"43188","stars":null,"title":"ZTE ZXDSL 831CII - Improper Access Restrictions"}],"tier":"weaponised"},"has_fix":null,"headline":"Missing authorization in n/a","id":"CVE-2017-16953","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"missing_authorization","year":"2017"},"n_packages":0,"n_references":3,"next":{"headline":"SQL injection in n/a","id":"CVE-2017-16955"},"packages":[],"prev":{"headline":"Denial of service in n/a","id":"CVE-2017-16952"},"products":["n/a"],"published":"2017-12-01","related":[],"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)"},{"class":"attribution","licence":"GPL-2.0-or-later","name":"Exploit-DB"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-05","vendors":["n/a"]},"summary":"Remote attackers can modify PPPoE configurations on ZTE ZXDSL 831CII devices without authentication via unauthenticated GET requests.","url":"https://insights.sbomify.com/CVE-2017-16953/"}
