===================================================================== CERT-Renater Note d'Information No. 2008/VULN191 _____________________________________________________________________ DATE : 29/05/2008 HARDWARE PLATFORM(S) : / OPERATING SYSTEM(S) : Systems running EMC AlphaStor. ====================================================================== http://labs.idefense.com/intelligence/vulnerabilities/display.php?id=702 http://labs.idefense.com/intelligence/vulnerabilities/display.php?id=703 ______________________________________________________________________ iDefense Security Advisory 05.27.08 http://labs.idefense.com/intelligence/vulnerabilities/ May 27, 2008 I. BACKGROUND AlphaStor is a suite of applications used for disk management. For more information, please see the vendor's website at the following URL. http://www.emc.com/products/detail/software/alphastor.htm II. DESCRIPTION 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. III. ANALYSIS 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. IV. DETECTION 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. V. WORKAROUND iDefense is currently unaware of any workarounds for these issues. VI. VENDOR RESPONSE "EMC has issued updates to correct this issue. More details can be found in knowledgebase article emc186391 available from powerlink.emc.com. EMC customers can further contact EMC Software Technical Support at 1-877-534-2867." VII. CVE INFORMATION The Common Vulnerabilities and Exposures (CVE) project has assigned the name CVE-2008-2158 to this issue. This is a candidate for inclusion in the CVE list (http://cve.mitre.org/), which standardizes names for security problems. VIII. DISCLOSURE TIMELINE 04/16/2008 Initial vendor notification 04/16/2008 Initial vendor response 05/27/2008 Coordinated public disclosure IX. CREDIT Three of these vulnerabilities were reported to iDefense by Stephen Fewer of Harmony Security (www.harmonysecurity.com). Two were discovered by Sean Larsson, iDefense Labs.

BACKGROUND AlphaStor is a suite of applications used for disk management. For more information, please see the vendor's website found at the following link. http://www.emc.com/products/detail/software/alphastor.htm II. DESCRIPTION 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. III. ANALYSIS 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. IV. DETECTION 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. V. WORKAROUND iDefense is currently unaware of any workarounds for this issue. VI. VENDOR RESPONSE "EMC has issued updates to correct this issue.
