QES, published on 24 Dec 2020. Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2020-2503 in the wild and no public exploit code.\n\nAffected product: QNAP Systems Inc. QES. 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-2020-2503/ (Markdown: https://insights.sbomify.com/CVE-2020-2503/index.md)","id":"CVE-2020-2503","markdown":"https://insights.sbomify.com/CVE-2020-2503/index.md","name":"CVE-2020-2503","record":{"aliases":["GHSA-v96c-c8j8-qhm7"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"QNAP QES","requires_auth":"low_privilege","summary":"Remote attackers can inject malicious scripts into QNAP QES File Station, 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":"qes","vendor":"qnap"}],"cvss":{"score":9,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/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"},{"id":"CWE-749","name":"Exposed Dangerous Method or Function"}],"description":"If exploited, this stored cross-site scripting vulnerability could allow remote attackers to inject malicious code in File Station.
