Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: Yes. Attackers have exploited CVE-2018-19943 in the wild since at least 24 May 2022, including in ransomware campaigns.\n\nAffected product: Qnap Qts. 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-2018-19943/ (Markdown: https://insights.sbomify.com/CVE-2018-19943/index.md)","id":"CVE-2018-19943","markdown":"https://insights.sbomify.com/CVE-2018-19943/index.md","name":"CVE-2018-19943","record":{"aliases":["GHSA-wh89-fj9h-4gr8"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"QNAP NAS firmware","requires_auth":"low_privilege","summary":"Remote attackers can inject malicious scripts into QNAP NAS web interfaces, potentially leading to code execution or account takeover.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"qnap","cpe":[{"product":"qts","vendor":"qnap"}],"cvss":{"score":8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:R/S:C/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-80","name":"Improper Neutralization of Script-Related HTML Tags in a Web Page"},{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"If exploited, this cross-site scripting vulnerability could allow remote attackers to inject malicious code.
