Service disruption via unbounded survey responses
Published Aug 2, 2023 · Updated Oct 17, 2024
Denial of service in Data Illusion ngSurvey 2.4.28 and earlier allows remote attackers to disrupt survey access via oversized responses. Text Field, Comment Field, and Contact Details responses lack server-side length enforcement, so the application accepts attacker-supplied values containing enormous character counts. Access to a survey containing one of these fields is sufficient; submission can crash the containerized application, and later viewing or export can exhaust browser memory or return HTTP 500 errors that block web access to respondent data.
