CVE-2021-35061Network attack vector

Browser script execution via unsanitized form parameters

Published Aug 30, 2021 · Updated Aug 4, 2024

Cross-site scripting in DRK Odenwaldkreis Testerfassung March-2021 allows remote attackers to inject script through HTML form fields. The public record identifies every form parameter across all components as an injection locus but does not disclose the exact server-side encoding failure. Exploitation requires a user to load the affected response, after which the script executes in that user's web context and can manipulate page content or access data available to the page.
