The vSphere Client (HTML5) contains a remote code execution vulnerability in a vCenter Server plugin. A malicious actor with network access to port 443 may exploit this issue to execute commands with unrestricted privileges on the underlying operating system that hosts vCenter Server. This affects VMware vCenter Server (7.x before 7.0 U1c, 6.7 before 6.7 U3l and 6.5 before 6.5 U3n) and VMware Cloud Foundation (4.x before 4.2 and 3.x before 3.10.1.2).

El VSphere Client (HTML5) contiene una vulnerabilidad de ejecución de código remota en un plugin de vCenter Server. Un actor malicioso con acceso de red al puerto 443 puede explotar este problema para ejecutar comandos con privilegios no restringidos en el sistema operativo subyacente que aloja vCenter Server. Esto afecta a VMware vCenter Server (versiones 7.x anteriores a 7.0 U1c, versiones 6.7 anteriores a 6.7 U3l y versiones 6.5 anteriores a 6.5 U3n) y VMware Cloud Foundation (versiones 4.x anteriores a 4.2 y versiones 3.x anteriores a 3.10.1.2)
