An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2021-32974 and fix it if it is affected.\n\nWhat it is: CVE-2021-32974 is a critical command injection vulnerability in Moxa NPort IAW5000A-I/O series firmware, published on 1 Apr 2022. 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-2021-32974 in the wild and no public exploit code.\n\nAffected product: Moxa NPort IAW5000A-I/O series 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-2021-32974/ (Markdown: https://insights.sbomify.com/CVE-2021-32974/index.md)","id":"CVE-2021-32974","markdown":"https://insights.sbomify.com/CVE-2021-32974/index.md","name":"CVE-2021-32974","record":{"aliases":["GHSA-w2p9-865g-3w64"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Serial Device Server","requires_auth":"none","summary":"Remote attackers can execute arbitrary commands on Moxa NPort IAW5000A-I/O devices due to improper input validation in the web server.","user_interaction":"not_required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"icscert","cpe":[{"product":"nport_iaw5150a-12i\\/o_firmware","vendor":"moxa"},{"product":"nport_iaw5150a-6i\\/o_firmware","vendor":"moxa"},{"product":"nport_iaw5250a-12i\\/o_firmware","vendor":"moxa"},{"product":"nport_iaw5250a-6i\\/o_firmware","vendor":"moxa"}],"cvss":{"score":9.8,"severity":"critical","source":"cna","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-78","name":"Improper Neutralization of Special Elements used in an OS Command"},{"id":"CWE-20","name":"Improper Input Validation"}],"description":"Improper input validation in the built-in web server in Moxa NPort IAW5000A-I/O series firmware version 2.2 or earlier may allow a remote attacker to execute commands.","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":"Moxa NPort IAW5000A-I/O Series Serial Device Server Improper Input Validation","id":"CVE-2021-32974","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"command_injection","year":"2021"},"n_packages":0,"n_references":2,"next":{"headline":"Memory corruption in Cscape","id":"CVE-2021-32975"},"packages":[],"prev":{"headline":"XML external entity in Panasonic FPWIN Pro","id":"CVE-2021-32972"},"products":["NPort IAW5000A-I/O series firmware"],"published":"2022-04-01","related":[{"cvss_score":9.8,"headline":"Moxa NPort IAW5000A-I/O Series Serial Device Server Stack-based Buffer Overflow","id":"CVE-2021-32976","kev_date_added":null,"published":"2022-04-01"},{"cvss_score":7.5,"headline":"Moxa NPort IAW5000A-I/O Series Serial Device Server Classic Buffer Overflow","id":"CVE-2021-32968","kev_date_added":null,"published":"2022-04-01"},{"cvss_score":7.5,"headline":"Moxa NPort IAW5000A-I/O Series Serial Device Server Improper Input Validation","id":"CVE-2021-32970","kev_date_added":null,"published":"2022-04-01"}],"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":"2025-04-16","vendors":["Moxa"]},"summary":"Remote attackers can execute arbitrary commands on Moxa NPort IAW5000A-I/O devices due to improper input validation in the web server.","url":"https://insights.sbomify.com/CVE-2021-32974/"}
