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-2021-1253 in the wild and no public exploit code.\n\nAffected product: Cisco Data Center Network Manager. 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-2021-1253/ (Markdown: https://insights.sbomify.com/CVE-2021-1253/index.md)","id":"CVE-2021-1253","markdown":"https://insights.sbomify.com/CVE-2021-1253/index.md","name":"CVE-2021-1253","record":{"aliases":["GHSA-qp95-2hv6-rp65"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["code_execution","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Cisco DCNM","requires_auth":"low_privilege","summary":"Remote attackers with network-operator privileges can execute cross-site scripting or reflected file download attacks against users of the Cisco DCNM web interface.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"data_center_network_manager","vendor":"cisco"}],"cvss":{"score":6.5,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:L","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"},{"id":"CWE-20","name":"Improper Input Validation"}],"description":"Multiple vulnerabilities in the web-based management interface of Cisco Data Center Network Manager (DCNM) could allow a remote attacker with network-operator privileges to conduct a cross-site scripting (XSS) attack or a reflected file download (RFD) attack against a user of the interface.
