Advisory Details:

High-Tech Bridge Security Research Lab has discovered multiple vulnerabilities in Samsung Kies synchronization utility that allows remote attacker to compromise affected system, execute and modify arbitrary files, modify arbitrary directories and modify System Registry with privileges of the current user.

1) Null Pointer Dereference in Samsung Kies: CVE-2012-3806

The vulnerability exists due to a null pointer dereference error in GetDataTable() method within the Samsung.DeviceService.DCA.DeviceDataParagonATGM.1 ActiveX control (DCAPARAGONGM.dll, GUID {7650BC47-036D-4D5B-95B4-9D622C8D00A4}, located by default in "C:\Program Files(x86)\Samsung\Kies\External\DeviceModules\"). A remote attacker can pass "tagDATATABLE_SUID" argument equal to 0 to the GetDataTable() method and rise an ACCESS_VIOLATION exception on a MOV EDX,[EAX] instruction, as EAX is previously zeroed by an unexpected NULL value in the memory region pointed by ECX:

Disassembly:

--------------------------------------------------

2A22B95 MOV ECX,[EBP+10]

2A22B98 MOV EAX,[ECX]

2A22B9A MOV EDX,[EAX] // Crash through

Null Pointer Dereference

2A22B9C PUSH 0

2A22B9E PUSH 0

2A22BA0 PUSH 2A71E68

2A22BA5 PUSH EAX

2A22BA6 MOV EAX,[EDX+50]

2A22BA9 CALL EAX

Registers:

--------------------------------------------------

EIP 02A22B9A

EAX 00000000

EBX 02A66774 -> 029E58F0

ECX 0022EBC0 -> 00000000

EDX 006DFCE2 -> 00030000

EDI 00000000

ESI 00000000

EBP 0022EB5C -> 0022EB7C

ESP 0022EB38 -> F2D508FE

2) Arbitrary File Execution in Samsung Kies: CVE-2012-3807

The CmdAgent.dll library, located by default in "C:\Program Files (x86)\Samsung\Kies\External\FirmwareUpdate\", has numerous arbitrary file execution vulnerabilities present in "CmdAgentLib" (GUID: {1FA56F8D-A66E-4ABD-9BC9-6F61469E59AD}), in particular in the 'ICommandAgent' interface of the "CommandAgent" class (GUID: {C668B648-A2BD-432C-854F-C8C0A275E1F1}). This default "ICommandAgent" interface has multiple functions and methods, and most of them can be leveraged by an untrusted source.
