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-2023-35140 and fix it if it is affected.\n\nWhat it is: CVE-2023-35140 is a medium-severity vulnerability in Zyxel GS1900-24EP firmware, published on 7 Nov 2023. 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-2023-35140 in the wild and no public exploit code.\n\nAffected product: Zyxel GS1900-24EP 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-2023-35140/ (Markdown: https://insights.sbomify.com/CVE-2023-35140/index.md)","id":"CVE-2023-35140","markdown":"https://insights.sbomify.com/CVE-2023-35140/index.md","name":"CVE-2023-35140","record":{"aliases":["GHSA-wcc8-wmx2-r8gp"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["privilege_escalation","data_modify"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Zyxel network switch","requires_auth":"low_privilege","summary":"An authenticated local user with read-only access can modify system settings on Zyxel GS1900-24EP switches due to improper privilege management.","user_interaction":"not_required","vuln_class":"privilege_escalation"},"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":"gs1900-24hpv2_firmware","vendor":"zyxel"},{"product":"gs1900-48_firmware","vendor":"zyxel"},{"product":"gs1900-48hpv2_firmware","vendor":"zyxel"},{"product":"gs1900-8_firmware","vendor":"zyxel"},{"product":"gs1900-8hp_firmware","vendor":"zyxel"}],"cvss":{"score":5.5,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-269","name":"Improper Privilege Management"}],"description":"The improper privilege management vulnerability in the Zyxel GS1900-24EP switch firmware version V2.70(ABTO.5) could allow an authenticated local user with read-only access to modify system settings 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":"Privilege escalation in GS1900-24EP firmware","id":"CVE-2023-35140","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"privilege_escalation","year":"2023"},"n_packages":0,"n_references":1,"next":{"headline":"Jenkins CSRF protection bypass vulnerability","id":"CVE-2023-35141"},"packages":[],"prev":{"headline":"Cross-site scripting in USG FLEX 50(W) series firmware","id":"CVE-2023-35139"},"products":["GS1900-24EP firmware"],"published":"2023-11-07","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":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2024-09-04","vendors":["Zyxel"]},"summary":"An authenticated local user with read-only access can modify system settings on Zyxel GS1900-24EP switches due to improper privilege management.","url":"https://insights.sbomify.com/CVE-2023-35140/"}
