ZDI-12-144 : EMC AutoStart ftAgent Opcode 0x4B Subcode 0x1D4C Parsing Remote Code Execution Vulnerability http://www.zerodayinitiative.com/advisories/ZDI-12-144 August 17, 2012 - -- CVE ID: CVE-2012-0409 - -- CVSS: 10, AV:N/AC:L/Au:N/C:C/I:C/A:C - -- Affected Vendors: EMC - -- Affected Products: EMC AutoStart - -- TippingPoint(TM) IPS Customer Protection: TippingPoint IPS customers have been protected against this vulnerability by Digital Vaccine protection filter ID 12435. For further product information on the TippingPoint IPS, visit: http://www.tippingpoint.com - -- Vulnerability Details: This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of the EMC Autostart ftAgent, which is deployed on machines managed by EMC Autostart by default. Authentication is not required to exploit this vulnerability. The specific flaw exists within the parsing routines for op-codes used by EMC Autostart ftAgent's proprietary network protocol. This ftAgent.exe service listens on TCP port 8045, and performs arithmetic for memory size calculation using values read from the network without validation. This arithmetic is susceptible to integer overflow, causing the memory allocation to be undersized, ultimately allowing for heap-based memory corruption. An attacker can exploit this condition to gain remote code execution as user SYSTEM. - -- Vendor Response: EMC has issued an update to correct this vulnerability.
