When executed with elevated privileges via UAC, the installer attempts to load version.dll from its execution directory, allowing DLL preloading. An attacker can supply a malicious version.dll alongside the legitimate installer so that, when a victim runs the installer and approves the UAC prompt, attacker-controlled code executes with administrator privileges. This can lead to full system compromise."}, {"lang": "es", "value": "Versiones 2.0.1.107 y anteriores de D-Link D-View 8 contienen una vulnerabilidad de ruta de búsqueda no controlada en el instalador. Cuando se ejecuta con privilegios elevados a través de UAC, el instalador intenta cargar version.dll desde su directorio de ejecución, permitiendo la precarga de DLL. Un atacante puede suministrar un version.dll malicioso junto con el instalador legítimo de modo que, cuando una víctima ejecuta el instalador y aprueba la solicitud de UAC, el código controlado por el atacante se ejecuta con privilegios de administrador.
