It can only be exploited from the same machine or local network, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2021-35032 and fix it if it is affected.\n\nWhat it is: CVE-2021-35032 is a medium-severity command injection vulnerability in Zyxel GS1900 series firmware, published on 28 Dec 2021. It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-35032 in the wild and no public exploit code.\n\nAffected product: Zyxel GS1900 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-2021-35032/ (Markdown: https://insights.sbomify.com/CVE-2021-35032/index.md)","id":"CVE-2021-35032","markdown":"https://insights.sbomify.com/CVE-2021-35032/index.md","name":"CVE-2021-35032","record":{"aliases":["GHSA-r9f4-jwv9-qjg8"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Zyxel GS1900 firmware","requires_auth":"high_privilege","summary":"An authenticated local user can execute arbitrary OS commands on Zyxel GS1900 series devices via a crafted function call in libsal.so.","user_interaction":"not_required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Zyxel","cpe":[{"product":"gs1900-10hp_firmware","vendor":"zyxel"},{"product":"gs1900-16_firmware","vendor":"zyxel"},{"product":"gs1900-24_firmware","vendor":"zyxel"},{"product":"gs1900-24e_firmware","vendor":"zyxel"},{"product":"gs1900-24ep_firmware","vendor":"zyxel"},{"product":"gs1900-24hp_firmware","vendor":"zyxel"},{"product":"gs1900-24hpv2_firmware","vendor":"zyxel"},{"product":"gs1900-48_firmware","vendor":"zyxel"},{"product":"gs1900-48hp_firmware","vendor":"zyxel"},{"product":"gs1900-48hpv2_firmware","vendor":"zyxel"},{"product":"gs1900-8_firmware","vendor":"zyxel"},{"product":"gs1900-8hp_firmware","vendor":"zyxel"}],"cvss":{"score":6.4,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:L/AC:H/PR:H/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"}],"description":"A vulnerability in the 'libsal.so' of the Zyxel GS1900 series firmware version 2.60 could allow an authenticated local user to execute arbitrary OS commands via a crafted function call.","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":"Command injection in GS1900 series firmware","id":"CVE-2021-35032","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"command_injection","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Hardcoded credentials in NBG6818 series firmware","id":"CVE-2021-35033"},"packages":[],"prev":{"headline":"Command injection in GS1900 series firmware","id":"CVE-2021-35031"},"products":["GS1900 series firmware"],"published":"2021-12-28","related":[{"cvss_score":8.8,"headline":"Zyxel GS1900 Series Switches Stack-Based Buffer Overflow","id":"CVE-2026-7273","kev_date_added":"2026-09-21","published":"2026-06-16"},{"cvss_score":9.8,"headline":"Command injection in n/a","id":"CVE-2019-15800","kev_date_added":null,"published":"2019-11-14"},{"cvss_score":9.8,"headline":"Hardcoded credentials in n/a","id":"CVE-2015-5988","kev_date_added":null,"published":"2015-12-31"},{"cvss_score":9.8,"headline":"Auth bypass in n/a","id":"CVE-2015-5989","kev_date_added":null,"published":"2015-12-31"},{"cvss_score":9.1,"headline":"Auth bypass in n/a","id":"CVE-2019-15803","kev_date_added":null,"published":"2019-11-14"},{"cvss_score":8.8,"headline":"Privilege escalation in n/a","id":"CVE-2019-15799","kev_date_added":null,"published":"2019-11-14"},{"cvss_score":8.8,"headline":"Cross-site request forgery in n/a","id":"CVE-2015-5990","kev_date_added":null,"published":"2015-12-31"}],"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":["Zyxel"]},"summary":"An authenticated local user can execute arbitrary OS commands on Zyxel GS1900 series devices via a crafted function call in libsal.so.","url":"https://insights.sbomify.com/CVE-2021-35032/"}
