AlphaStor is a suite of applications used for disk management. For more information, please see the vendor's website at the following URL.
Remote exploitation of multiple stack based buffer overflow vulnerabilities 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 Server Agent. The Server Agent is one of the core components of AlphaStor, and is used to initiate disk management requests. The Agent consists of several processes, one of which is the AlphaStor Command Line Interface process. This process listens on TCP port 41025, and is prone to multiple stack based buffer overflow vulnerabilities.
Exploitation of these vulnerabilities results in the execution of arbitrary code with the privileges of the affected service, usually SYSTEM. The vulnerabilities occur before any authentication, so they can be exploited by anonymous attackers with the ability to create a TCP connection to port 41025 on the server.
iDefense has confirmed the existence of these vulnerabilities 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 these issues.
