Unisys WebPerfect Image Suite versions 3.0.3960.22810 and 3.0.3960.22604 expose a deprecated .NET Remoting TCP channel that allows remote unauthenticated attackers to leak NTLMv2 machine-account hashes by supplying a Windows UNC path as a target file argument through object-unmarshalling techniques. Attackers can capture the leaked NTLMv2 hash and relay it to other hosts to achieve privilege escalation or lateral movement depending on network configuration and patch level.
Unisys WebPerfect Image Suite versions 3.0.3960.22810 and 3.0.3960.22604 expose a deprecated .NET Remoting TCP channel that allows remote unauthenticated attackers to leak NTLMv2 machine-account hashes by supplying a Windows UNC path as a target file argument through object-unmarshalling techniques. Attackers can capture the leaked NTLMv2 hash and relay it to other hosts to achieve privilege escalation or lateral movement depending on network configuration and patch level.
Las versiones 3.0.3960.22810 y 3.0.3960.22604 de Unisys WebPerfect Image Suite exponen un canal TCP de .NET Remoting obsoleto que permite a atacantes remotos no autenticados filtrar hashes de cuentas de máquina NTLMv2 al proporcionar una ruta UNC de Windows como argumento de archivo de destino mediante técnicas de desmarshalling de objetos. Los atacantes pueden capturar el hash NTLMv2 filtrado y retransmitirlo a otros hosts para lograr escalada de privilegios o movimiento lateral dependiendo de la configuración de red y el nivel de parche.
