CVE-2020-29029Network attack vector

Unauthenticated JavaScript execution via Web GUI input

Published Mar 5, 2021 · Updated Sep 16, 2024

Cross-site scripting in Secomea GateManager before 9.4 allows remote attackers to execute arbitrary JavaScript through the Web GUI. Secomea identifies improper input validation but has not named the affected field or disclosed how its value reaches generated page content. Unauthenticated network access is sufficient; the published material does not define the JavaScript execution context or concrete downstream effects.
