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-2026-21718 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-2026-21718/ (Markdown: https://insights.sbomify.com/CVE-2026-21718/index.md)","id":"CVE-2026-21718","markdown":"https://insights.sbomify.com/CVE-2026-21718/index.md","name":"CVE-2026-21718","record":{"aliases":["GHSA-7r34-g88h-g49f"],"analysis":{"component_type":"ics_ot","fix_type":"patch","impacts":["code_execution","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Copeland XWEB controller","requires_auth":"none","summary":"Attackers can bypass authentication via weak cryptography to execute code on Copeland XWEB systems, requiring immediate patching for industrial control security.","user_interaction":"not_required","vuln_class":"weak_cryptography"},"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":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-327","name":"Use of a Broken or Risky Cryptographic Algorithm"}],"description":"An authentication bypass vulnerability exists in Copeland XWEB Pro \nversion 1.12.1 and prior, enabling any attackers to bypass the \nauthentication requirement and achieve pre-authenticated code execution \non the system.","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 Use of a Broken or Risky Cryptographic Algorithm","id":"CVE-2026-21718","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"weak_cryptography","year":"2026"},"n_packages":0,"n_references":3,"next":{"headline":"Command injection in CubeCart","id":"CVE-2026-21719"},"packages":[],"prev":{"headline":"Denial of service in node","id":"CVE-2026-21717"},"products":["Copeland XWEB 300D PRO","Copeland XWEB 500B PRO","Copeland XWEB 500D PRO"],"published":"2026-02-27","related":[{"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":"yes","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-03-02","vendors":["Copeland"]},"summary":"Attackers can bypass authentication via weak cryptography to execute code on Copeland XWEB systems, requiring immediate patching for industrial control security.","url":"https://insights.sbomify.com/CVE-2026-21718/"}
