CVE-2021-35229Network attack vector

Data disclosure via complex SQL query XSS

Published Apr 21, 2022 · Updated Sep 16, 2024

Cross-site scripting in SolarWinds Database Performance Monitor 2022.1.7779 and earlier allows remote attackers to read data via a complex SQL query. The vendor identifies complex SQL-query processing as the trigger but has not disclosed the affected interface or the output-encoding operation that mishandles query content. No account or user interaction is required to reach the condition, and the documented consequence is limited to data exposure.
