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-2026-20797 in the wild and no public exploit code.\n\nAffected product: Copeland XWEB 300D PRO. 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-2026-20797/ (Markdown: https://insights.sbomify.com/CVE-2026-20797/index.md)","id":"CVE-2026-20797","markdown":"https://insights.sbomify.com/CVE-2026-20797/index.md","name":"CVE-2026-20797","record":{"aliases":["GHSA-rgf4-44r9-4r27"],"analysis":{"component_type":"ics_ot","fix_type":"no_fix_stated","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Copeland XWEB controller","requires_auth":"none","summary":"Unauthenticated attackers can cause a stack-based buffer overflow in Copeland XWEB Pro, leading to program termination and denial of service.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"icscert","cpe":[{"product":"xweb_300d_pro_firmware","vendor":"copeland"},{"product":"xweb_500b_pro_firmware","vendor":"copeland"},{"product":"xweb_500d_pro_firmware","vendor":"copeland"}],"cvss":{"score":4.3,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L","version":"3.1"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"},{"id":"CWE-121","name":"Stack-based Buffer Overflow"}],"description":"A stack based buffer overflow exists in an API route of XWEB Pro version\n 1.12.1 and prior, enabling unauthenticated attackers to cause stack \ncorruption and a termination of the program.","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":"Copeland XWEB and XWEB Pro Stack-based Buffer Overflow","id":"CVE-2026-20797","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2026"},"n_packages":0,"n_references":3,"next":{"headline":"Privilege escalation in Battery Life Diagnostic Tool software","id":"CVE-2026-20799"},"packages":[],"prev":{"headline":"Time-of-check time-of-use vulnerability in common teams API","id":"CVE-2026-20796"},"products":["Copeland XWEB 300D PRO","Copeland XWEB 500B PRO","Copeland XWEB 500D PRO"],"published":"2026-02-27","related":[{"cvss_score":10,"headline":"Copeland XWEB and XWEB Pro Use of a Broken or Risky Cryptographic Algorithm","id":"CVE-2026-21718","kev_date_added":null,"published":"2026-02-27"},{"cvss_score":9,"headline":"Copeland XWEB and XWEB Pro OS Command Injection","id":"CVE-2026-24663","kev_date_added":null,"published":"2026-02-27"},{"cvss_score":8.6,"headline":"Copeland XWEB and XWEB Pro Unexpected Status Code or Return Value","id":"CVE-2026-25085","kev_date_added":null,"published":"2026-02-27"},{"cvss_score":8,"headline":"Copeland XWEB and XWEB Pro OS Command Injection","id":"CVE-2026-20742","kev_date_added":null,"published":"2026-02-27"},{"cvss_score":8,"headline":"Copeland XWEB and XWEB Pro OS Command Injection","id":"CVE-2026-20764","kev_date_added":null,"published":"2026-02-27"},{"cvss_score":8,"headline":"Copeland XWEB and XWEB Pro OS Command Injection","id":"CVE-2026-20902","kev_date_added":null,"published":"2026-02-27"},{"cvss_score":8,"headline":"Copeland XWEB and XWEB Pro OS Command Injection","id":"CVE-2026-20910","kev_date_added":null,"published":"2026-02-27"}],"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":"2026-05-10","vendors":["Copeland"]},"summary":"Unauthenticated attackers can cause a stack-based buffer overflow in Copeland XWEB Pro, leading to program termination and denial of service.","url":"https://insights.sbomify.com/CVE-2026-20797/"}
