It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: Yes. Attackers have exploited CVE-2026-7273 in the wild since at least 21 Sep 2026.\n\nAffected product: Zyxel GS1900-10HP 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-2026-7273/ (Markdown: https://insights.sbomify.com/CVE-2026-7273/index.md)","id":"CVE-2026-7273","markdown":"https://insights.sbomify.com/CVE-2026-7273/index.md","name":"CVE-2026-7273","record":{"aliases":["GHSA-rrv4-8jq5-8j78"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Zyxel managed switch","requires_auth":"none","summary":"A stack-based buffer overflow in the CGI program allows unauthenticated LAN attackers to execute OS commands via crafted HTTP requests.","user_interaction":"not_required","vuln_class":"memory_corruption"},"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":8.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-121","name":"Stack-based Buffer Overflow"}],"description":"A stack-based buffer overflow vulnerability in the CGI program of Zyxel GS1900-48HPv2 firmware versions through 2.90(ABTQ.1)C0 could allow a LAN-based, unauthenticated attacker to exploit the flaw and potentially execute OS commands via a crafted HTTP request.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"exploited"},"has_fix":null,"headline":"Zyxel GS1900 Series Switches Stack-Based Buffer Overflow","id":"CVE-2026-7273","indexable":true,"kev":{"dateAdded":"2026-09-21","dueDate":"2026-09-24","knownRansomwareCampaignUse":"Unknown","product":"GS1900 Series Switches","requiredAction":"Apply mitigations in accordance with vendor instructions, ensuring compliance with CISA’s BOD 26-04 Prioritizing Security Updates Based on Risk (see URL in Notes) guidance and CISA’s “Forensics Triage Requirements” (see URL in Notes).
