-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ZDI-12-122: EMC AutoStart ftAgent Opcode 65 Parsing Remote Code Execution Vulnerability http://www.zerodayinitiative.com/advisories/ZDI-12-122 July 12, 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 EMC Autostart. Authentication is not required to exploit this vulnerability. The specific flaw exists within the ftAgent.exe service, which listens by default on TCP port 8045. When handling messages with opcode 65 (0x41) and subcode 18 (0x12), the process performs arithmetic on an unvalidated user-supplied value used to determine the size of a new heap buffer, allowing a potential integer wrap to cause a heap buffer overflow. This vulnerability can be leveraged to execute code under the context of the SYSTEM user. - -- Vendor Response: EMC has issued an update to correct this vulnerability.
