Summary

Viewsonic vCast in ViewSonic ViewBoard, from v0.0.0 through v3.2.715, has an input injection flaw in its exposed network services (CWE-74). Special characters in input are not neutralized before a downstream component uses it, so a remote attacker can inject arbitrary input into service endpoints. The attacker needs no authentication, only network HTTP requests to unauthenticated endpoints.
