An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2022-43389 and fix it if it is affected.\n\nWhat it is: CVE-2022-43389 is a high-severity memory corruption vulnerability in Zyxel NR7101 firmware, published on 11 Jan 2023. 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-2022-43389 in the wild and no public exploit code.\n\nAffected product: Zyxel NR7101 firmware. 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-2022-43389/ (Markdown: https://insights.sbomify.com/CVE-2022-43389/index.md)","id":"CVE-2022-43389","markdown":"https://insights.sbomify.com/CVE-2022-43389/index.md","name":"CVE-2022-43389","record":{"aliases":["GHSA-356g-gwg5-3vmc"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Zyxel NR7101 firmware","requires_auth":"none","summary":"An unauthenticated attacker can execute OS commands or cause denial-of-service on Zyxel NR7101 devices via a buffer overflow in the web server library.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Zyxel","cpe":[{"product":"ep240p_firmware","vendor":"zyxel"},{"product":"lte3202-m437_firmware","vendor":"zyxel"},{"product":"lte3316-m604_firmware","vendor":"zyxel"},{"product":"lte7480-m804_firmware","vendor":"zyxel"},{"product":"lte7490-m904_firmware","vendor":"zyxel"},{"product":"nebula_fwa510_firmware","vendor":"zyxel"},{"product":"nebula_fwa710_firmware","vendor":"zyxel"},{"product":"nebula_nr7101_firmware","vendor":"zyxel"},{"product":"nr5103_firmware","vendor":"zyxel"},{"product":"nr5103e_firmware","vendor":"zyxel"},{"product":"nr7101_firmware","vendor":"zyxel"},{"product":"nr7102_firmware","vendor":"zyxel"},{"product":"nr7103_firmware","vendor":"zyxel"},{"product":"pm7320-b0_firmware","vendor":"zyxel"},{"product":"pmg5317-t20b_firmware","vendor":"zyxel"},{"product":"pmg5617ga_firmware","vendor":"zyxel"},{"product":"pmg5622ga_firmware","vendor":"zyxel"}],"cvss":{"score":8.6,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:H","version":"3.1"},"cwes":[{"id":"CWE-120","name":"Buffer Copy without Checking Size of Input"}],"description":"A buffer overflow vulnerability in the library of the web server in Zyxel NR7101 firmware prior to V1.15(ACCC.3)C0, which could allow an unauthenticated attacker to execute some OS commands or to cause denial-of-service (DoS) conditions on a vulnerable device.","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":"Memory corruption in NR7101 firmware","id":"CVE-2022-43389","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2022"},"n_packages":0,"n_references":1,"next":{"headline":"Command injection in NR7101 firmware","id":"CVE-2022-43390"},"packages":[],"prev":{"headline":"IBM Aspera Console cross-site scripting","id":"CVE-2022-43384"},"products":["NR7101 firmware"],"published":"2023-01-11","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)"}],"ssvc":{"automatable":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-04-09","vendors":["Zyxel"]},"summary":"An unauthenticated attacker can execute OS commands or cause denial-of-service on Zyxel NR7101 devices via a buffer overflow in the web server library.","url":"https://insights.sbomify.com/CVE-2022-43389/"}
