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-2020-18331 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-2020-18331/ (Markdown: https://insights.sbomify.com/CVE-2020-18331/index.md)","id":"CVE-2020-18331","markdown":"https://insights.sbomify.com/CVE-2020-18331/index.md","name":"CVE-2020-18331","record":{"aliases":["GHSA-w48q-2q3f-h2f8"],"analysis":{"component_type":"network_device","fix_type":"no_fix_stated","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"ChinaMobile PLC Router","requires_auth":"none","summary":"Attackers can exploit a directory traversal flaw in the ChinaMobile PLC Wireless Router to read arbitrary files via the getpage parameter.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"gpn2.4p21-c-cn_firmware","vendor":"chinamobileltd"}],"cvss":{"score":9.1,"severity":"critical","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-22","name":"Improper Limitation of a Pathname to a Restricted Directory"}],"description":"Directory traversal vulnerability in ChinaMobile PLC Wireless Router model GPN2.4P21-C-CN running the firmware version W2000EN-01(hardware platform Gpn2.4P21-C_WIFI-V0.05), via the getpage parameter to /cgi-bin/webproc.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":null,"headline":"Path traversal in n/a","id":"CVE-2020-18331","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"path_traversal","year":"2020"},"n_packages":0,"n_references":2,"next":{"headline":"Cross-site scripting in n/a","id":"CVE-2020-18336"},"packages":[],"prev":{"headline":"Path traversal in n/a","id":"CVE-2020-18330"},"products":["n/a"],"published":"2023-01-25","related":[{"cvss_score":9.1,"headline":"Path traversal in n/a","id":"CVE-2020-18330","kev_date_added":null,"published":"2023-01-25"},{"cvss_score":8.8,"headline":"Missing authorization in n/a","id":"CVE-2019-6279","kev_date_added":null,"published":"2019-03-19"},{"cvss_score":8.8,"headline":"Cross-site request forgery in n/a","id":"CVE-2019-6282","kev_date_added":null,"published":"2019-03-19"},{"cvss_score":7.5,"headline":"Missing authorization in GPN2.4P21-C-CN","id":"CVE-2019-1010136","kev_date_added":null,"published":"2019-07-19"}],"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":"yes","exploitation":"poc","technical_impact":"total"},"state":"PUBLISHED","updated":"2025-04-01","vendors":["n/a"]},"summary":"Attackers can exploit a directory traversal flaw in the ChinaMobile PLC Wireless Router to read arbitrary files via the getpage parameter.","url":"https://insights.sbomify.com/CVE-2020-18331/"}
