Descriptions

A vulnerability has been identified in APOGEE PXC Compact (BACnet) (All versions < V3.5.5), APOGEE PXC Compact (P2 Ethernet) (All versions < V2.8.20), APOGEE PXC Modular (BACnet) (All versions < V3.5.5), APOGEE PXC Modular (P2 Ethernet) (All versions < V2.8.20), Nucleus NET (All versions < V5.2), Nucleus ReadyStart V3 (All versions < V2012.12), Nucleus Source Code (All versions), PLUSCONTROL 1st Gen (All versions), TALON TC Compact (BACnet) (All versions < V3.5.5), TALON TC Modular (BACnet) (All versions < V3.5.5). Initial Sequence Numbers (ISNs) for TCP connections are derived from an insufficiently random source. As a result, the ISN of current and future TCP connections could be predictable. An attacker could hijack existing sessions or spoof future ones.

Se ha identificado una vulnerabilidad en Capital VSTAR (Todas las versiones), Nucleus NET (Todas las versiones anteriores a V5.2), Nucleus ReadyStart V3 (Todas las versiones anteriores a V2012.12), Nucleus Source Code (Todas las versiones), PLUSCONTROL 1st Gen (Todas las versiones). Los números de secuencia iniciales (ISN) para las conexiones TCP se derivan de una fuente insuficientemente aleatoria. Como resultado, el ISN de las conexiones TCP actuales y futuras podría ser predecible. Un atacante podría secuestrar las sesiones existentes o falsificar las futuras
