EasyBlocks IPv6, published on 8 Apr 2020. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2020-5550 in the wild and no public exploit code.\n\nAffected product: Plat'Home Co.,Ltd. EasyBlocks IPv6. 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-2020-5550/ (Markdown: https://insights.sbomify.com/CVE-2020-5550/index.md)","id":"CVE-2020-5550","markdown":"https://insights.sbomify.com/CVE-2020-5550/index.md","name":"CVE-2020-5550","record":{"aliases":["GHSA-cg22-wvf3-j78q"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["account_takeover","data_read","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"IPv6 network device","requires_auth":"none","summary":"Remote attackers can hijack sessions to impersonate users and access the management console, leading to data disclosure or alteration.","user_interaction":"required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jpcert","cpe":[{"product":"easyblocks_ipv6_enterprise_firmware","vendor":"plathome"},{"product":"easyblocks_ipv6_firmware","vendor":"plathome"}],"cvss":{"score":8.1,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-384","name":"Session Fixation"}],"description":"Session fixation vulnerability in EasyBlocks IPv6 Ver. 2.0.1 and earlier, and Enterprise Ver. 2.0.1 and earlier allows remote attackers to impersonate a registered user and log in the management console, that may result in information alteration/disclosure via unspecified vectors.","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":"Auth bypass in EasyBlocks IPv6","id":"CVE-2020-5550","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"auth_bypass","year":"2020"},"n_packages":0,"n_references":3,"next":{"headline":"Command injection in DCU (Display Control Unit)","id":"CVE-2020-5551"},"packages":[],"prev":{"headline":"Cross-site request forgery in EasyBlocks IPv6","id":"CVE-2020-5549"},"products":["EasyBlocks IPv6"],"published":"2020-04-08","related":[{"cvss_score":8.8,"headline":"Cross-site request forgery in EasyBlocks IPv6","id":"CVE-2020-5549","kev_date_added":null,"published":"2020-04-08"}],"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":"2024-08-04","vendors":["Plat'Home Co.,Ltd."]},"summary":"Remote attackers can hijack sessions to impersonate users and access the management console, leading to data disclosure or alteration.","url":"https://insights.sbomify.com/CVE-2020-5550/"}
