An attacker needs administrator access to exploit it, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2021-21434 in the wild and no public exploit code.\n\nAffected product: OTRS AG Survey. 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-2021-21434/ (Markdown: https://insights.sbomify.com/CVE-2021-21434/index.md)","id":"CVE-2021-21434","markdown":"https://insights.sbomify.com/CVE-2021-21434/index.md","name":"CVE-2021-21434","record":{"aliases":["GHSA-2rff-cr3q-94jm","UBUNTU-CVE-2021-21434"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"OTRS Survey Module","requires_auth":"high_privilege","summary":"A survey administrator can inject malicious code into surveys, leading to script execution in the agent interface for other users.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"OTRS","cpe":[{"product":"survey","vendor":"otrs"}],"cvss":{"score":3.5,"severity":"low","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:R/S:U/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"Survey administrator can craft a survey in such way that malicious code can be executed in the agent interface (i.e. another agent who wants to make changes in the survey).
