An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2023-49262 and fix it if it is affected.\n\nWhat it is: CVE-2023-49262 is a critical authentication bypass vulnerability in Hongdian H8951-4G-ESP, published on 12 Jan 2024. 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-2023-49262 in the wild and no public exploit code.\n\nAffected product: Hongdian H8951-4G-ESP. 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-2023-49262/ (Markdown: https://insights.sbomify.com/CVE-2023-49262/index.md)","id":"CVE-2023-49262","markdown":"https://insights.sbomify.com/CVE-2023-49262/index.md","name":"CVE-2023-49262","record":{"aliases":["GHSA-8p4h-69c2-3352"],"analysis":{"component_type":"iot_embedded","fix_type":"no_fix_stated","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Hongdian H8951-4G-ESP","requires_auth":"none","summary":"Attackers can bypass authentication by overflowing the Cookie authentication field in Hongdian H8951-4G-ESP devices with an active session.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"CERT-PL","cpe":[{"product":"h8951-4g-esp_firmware","vendor":"hongdian"}],"cvss":{"score":9.8,"severity":"critical","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-287","name":"Improper Authentication"},{"id":"CWE-190","name":"Integer Overflow or Wraparound"}],"description":"The authentication mechanism can be bypassed by overflowing the value of the Cookie \"authentication\" field, provided there is an active user session.","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":"Buffer overflow vulnerability in Cookie authentication field","id":"CVE-2023-49262","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"auth_bypass","year":"2023"},"n_packages":0,"n_references":2,"next":{"headline":"Hotel Management v1.0 - Multiple Reflected Cross-Site Scripting (XSS)","id":"CVE-2023-49269"},"packages":[],"prev":{"headline":"Sensitive authentication-related value accessible publicly","id":"CVE-2023-49261"},"products":["H8951-4G-ESP"],"published":"2024-01-12","related":[{"cvss_score":9.8,"headline":"Predefined root password","id":"CVE-2023-49253","kev_date_added":null,"published":"2024-01-12"},{"cvss_score":9.8,"headline":"Router console accessible without authentication","id":"CVE-2023-49255","kev_date_added":null,"published":"2024-01-12"},{"cvss_score":8.8,"headline":"Command injection in the network test tools","id":"CVE-2023-49254","kev_date_added":null,"published":"2024-01-12"},{"cvss_score":8.8,"headline":"Command execution using the certificate upload utility","id":"CVE-2023-49257","kev_date_added":null,"published":"2024-01-12"},{"cvss_score":7.5,"headline":"Predictable encryption passphrase used in publicly accessible configuration file","id":"CVE-2023-49256","kev_date_added":null,"published":"2024-01-12"},{"cvss_score":7.5,"headline":"Bruteforcing authentication cookie for a given user","id":"CVE-2023-49259","kev_date_added":null,"published":"2024-01-12"}],"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":"yes","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2025-06-03","vendors":["Hongdian"]},"summary":"Attackers can bypass authentication by overflowing the Cookie authentication field in Hongdian H8951-4G-ESP devices with an active session.","url":"https://insights.sbomify.com/CVE-2023-49262/"}
