An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2023-3939 and fix it if it is affected.\n\nWhat it is: CVE-2023-3939 is a critical command injection vulnerability in ZkTeco-based OEM devices with firmware ZAM170-NF-1.8.25-7354-Ver1.0.0, published on 21 May 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-2023-3939 in the wild and no public exploit code.\n\nAffected product: ZkTeco-based OEM devices with firmware ZAM170-NF-1.8.25-7354-Ver1.0.0. 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-2023-3939/ (Markdown: https://insights.sbomify.com/CVE-2023-3939/index.md)","id":"CVE-2023-3939","markdown":"https://insights.sbomify.com/CVE-2023-3939/index.md","name":"CVE-2023-3939","record":{"aliases":["GHSA-mvc4-fr9f-g4j8"],"analysis":{"component_type":"iot_embedded","fix_type":"no_fix_stated","impacts":["code_execution","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"ZkTeco OEM devices","requires_auth":"none","summary":"Attackers can execute arbitrary OS commands with superuser privileges on ZkTeco-based OEM devices, leading to full system compromise.","user_interaction":"not_required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Kaspersky","cpe":[],"cvss":{"score":10,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-78","name":"Improper Neutralization of Special Elements used in an OS Command"}],"description":"Improper Neutralization of Special Elements used in an OS Command ('OS \nCommand Injection') vulnerability in ZkTeco-based OEM devices allows OS \nCommand Injection. \nSince all the found command implementations are executed from the \nsuperuser, their impact is the maximum possible.\nThis issue affects \nZkTeco-based OEM devices (ZkTeco ProFace X, Smartec ST-FR043, Smartec \nST-FR041ME and possibly others) with the ZAM170-NF-1.8.25-7354-Ver1.0.0 \nand possibly other.","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":"Multiple command injection in ZkTeco-based OEM devices","id":"CVE-2023-3939","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"command_injection","year":"2023"},"n_packages":0,"n_references":1,"next":{"headline":"Multiple arbitrary file reads in ZkTeco-based OEM devices","id":"CVE-2023-3940"},"packages":[],"prev":{"headline":"Bypassing ZkTeco-based OEM devices/ZKTeco biometric authentication system via SQLi in QR code","id":"CVE-2023-3938"},"products":["ZkTeco-based OEM devices with firmware ZAM170-NF-1.8.25-7354-Ver1.0.0"],"published":"2024-05-21","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"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":"2024-08-02","vendors":["ZkTeco"]},"summary":"Attackers can execute arbitrary OS commands with superuser privileges on ZkTeco-based OEM devices, leading to full system compromise.","url":"https://insights.sbomify.com/CVE-2023-3939/"}
