Q’center, published on 3 Jun 2021. Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-28807 in the wild and no public exploit code.\n\nAffected product: QNAP Systems Inc. Q’center. 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-2021-28807/ (Markdown: https://insights.sbomify.com/CVE-2021-28807/index.md)","id":"CVE-2021-28807","markdown":"https://insights.sbomify.com/CVE-2021-28807/index.md","name":"CVE-2021-28807","record":{"aliases":["GHSA-4g4m-4574-88xm"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"QNAP NAS Q'center","requires_auth":"low_privilege","summary":"Remote attackers can inject malicious scripts into QNAP NAS Q'center via reflected XSS, potentially leading to code execution or account takeover.","user_interaction":"not_required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"qnap","cpe":[{"product":"q\\'center","vendor":"qnap"}],"cvss":{"score":7.7,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"A post-authentication reflected XSS vulnerability has been reported to affect QNAP NAS running Q’center.
