CVE-2025-3837

Unauthenticated code execution via crafted request parameter

Published Apr 21, 2025 · Updated Apr 21, 2025

Improper input validation in Saviynt OVA based Connect allows remote attackers on the local network to execute code through a crafted request. The published advisory states that a specific request parameter accepts a code-execution payload, but it does not identify the parameter or the faulty validation operation. Access requires adjacency to the customer network and no authentication or user interaction; successful exploitation compromises the hosting infrastructure.
