EMC AlphaStor Library Manager Arbitrary Command Execution Vulnerability



AlphaStor is a suite of applications used for disk management. For more information, please see the vendor's website found at the following link.


Remote exploitation of an arbitrary command execution vulnerability in EMC Corp.'s AlphaStor could allow an attacker to execute arbitrary code with SYSTEM privileges.

AlphaStor consists of multiple applications, one of which is the Library Manager. The Library Manager is used to manage the replacement of disk drives in distributed locations. The Manager consists of a single process, the "robotd" process, that listens on TCP port 3500 for incoming connections.

The Library Manager is prone to an arbitrary command execution vulnerability. When sent a specific request, "robotd" will use a string from the packet as a command to execute on the system via the CreateProcess() function. This allows an attacker to run arbitrary programs on the host with SYSTEM privileges.


Exploitation of this vulnerability results in the execution of arbitrary code with the privileges of the affected service, usually SYSTEM. The vulnerability occurs before any authentication, so it can be exploited by anonymous attackers with the ability to create a TCP connection to port 3500 on the server.

Since the vulnerability allows an attacker to run arbitrary programs with arbitrary arguments, little skill is required for exploitation.


iDefense has confirmed the existence of this vulnerability in AlphaStor version 3.1 SP1 for Windows. Previous versions, as well as versions for other platforms, may also be affected.


iDefense is currently unaware of any workarounds for this issue.
