An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2021-20717 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- ec-cube/ec-cube (Packagist): affected from 4.0.0 up to 4.0.5; no fix listed\n- ec-cube/ec-cube (Packagist): affected from 4.0.0 up to 4.0.5; no fix listed\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-2021-20717/ (Markdown: https://insights.sbomify.com/CVE-2021-20717/index.md)","id":"CVE-2021-20717","markdown":"https://insights.sbomify.com/CVE-2021-20717/index.md","name":"CVE-2021-20717","record":{"aliases":["GHSA-c8mx-43cq-993w"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"EC-CUBE e-commerce platform","requires_auth":"none","summary":"Remote attackers can inject scripts into EC-CUBE input fields, leading to arbitrary script execution in administrators' browsers.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jpcert","cpe":[{"product":"ec-cube","vendor":"ec-cube"}],"cvss":{"score":6.1,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"Cross-site scripting vulnerability in EC-CUBE 4.0.0 to 4.0.5 allows a remote attacker to inject a specially crafted script in the specific input field of the EC web site which is created using EC-CUBE.
