PART I Critical Vulnerabilities Part I for this issue has been compiled by Josh Bronson at TippingPoint, a division of HP, as a by-product of that company's continuous effort to ensure that its intrusion prevention products effectively block exploits using known vulnerabilities. TippingPoint's analysis is complemented by input from a council of security managers from twelve large organizations who confidentially share with SANS the specific actions they have taken to protect their systems. A detailed description of the process may be found at http://www.sans.org/newsletters/risk/#process

Description: Siemens has released a patch for a vulnerability affecting its SIMATIC WinCC software. WinCC is used visualize industrial plant processes and can be used on its own or as a component of a larger SCADA system. It is widely deployed in several industries. Little information is available for this vulnerability. Siemens reports that it exists in the "Tag Simulator" of "WinCC flexible." By enticing a target to open a malicious WinCC file, an attacker can exploit this vulnerability in order to execute arbitrary code on the target's machine.
Status: vendor confirmed, updates available
Description: BroadWin WebAccess is susceptible to format string and memory corruption vulnerabilities, according to Luigi Auriemma. WebAccess, web-based Human Machine Interface (HMI) and SCADA software, is used in industrial settings to view, control, and configure automation systems. The format string vulnerability is due to the application passing a string from a call to the OcxSpool method directly to vsprintf, allowing an attacker to pass arbitrary format strings to that function. The memory corruption is due to the code trusting attacker-controlled stream identifiers in the WriteTextData and CloseFile methods. By enticing a target to view a malicious page, an attacker can exploit these vulnerabilities in order to execute arbitrary code on a target's machine.
Status: vendor not confirmed, updates not available
Part II -- Comprehensive List of Newly Discovered Vulnerabilities from Qualys (www.qualys.com) This list is compiled by Qualys ( www.qualys.com ) as part of that company's ongoing effort to ensure its vulnerability management web service tests for all known vulnerabilities that can be scanned. As of this week Qualys scans for 12254 unique vulnerabilities. For this special SANS community listing, Qualys also includes vulnerabilities that cannot be scanned remotely. ______________________________________________________________________
