Stored XSS in Ivanti Endpoint Manager incomingdata API
CVE-2025-10573 is a critical stored cross-site scripting vulnerability in Ivanti Endpoint Manager (EPM) affecting versions prior to 2024 SU4 SR1. The flaw is in the incomingdata web API and associated CGI handler, postcgi.exe, which processes device scan data submitted in key=value format. An unauthenticated attacker can submit crafted fake managed-endpoint scan data containing malicious JavaScript. That data is subsequently embedded in the EPM administrative web dashboard without proper sanitization or output encoding. When an administrator views the poisoned dashboard, the attacker-controlled script executes in the context of the administrator’s browser session. This enables session hijacking and can turn a client-side XSS condition into effective administrative compromise of the EPM environment.
