This week's top vulnerability comes from the same vendor in the same product category as last week: A backup product is once again on the "critical list" and again it is CA's backup product. A big problem is that many people think back up software patches automatically. It doesn't. If you use BrightStor, quick action is really important. The iPhone also has a big vulnerability.

@RISK is the SANS community's consensus bulletin summarizing the most important vulnerabilities and exploits identified during the past week and providing guidance on appropriate actions to protect your systems (PART I). It also includes a comprehensive list of all new vulnerabilities discovered in the past week (PART II).

Part I for this issue has been compiled by Rob King at TippingPoint, a division of 3Com, 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/cva/#process
Description: CA BrightStor Hierarchical Storage Manager (HSM) is CA's enterprise storage management solution. This product contains multiple vulnerabilities in various components, including multiple buffer and integer overflows and multiple SQL injection vulnerabilities. A remote attacker could exploit any of these vulnerabilities to execute arbitrary code with the privileges of the vulnerable process (often SYSTEM). Some technical details for these vulnerabilities are publicly available. It is believed that these vulnerabilities are distinct from those discussed in last week's @RISK.
Status: CA confirmed, updates available.
Description: The Apple iPhone contains multiple vulnerabilities in its handling of web and email content, Bluetooth messages, and other data. A specially crafted Bluetooth packet sent by an attacker within physical Bluetooth range could trigger a buffer overflow vulnerability and allow an attacker to execute arbitrary code on the iPhone. Specially crafted web pages or email messages could cause phone numbers to be dialed without confirmation, or could spoof phone numbers such that the number dialed is different from the number displayed for confirmation. Other vulnerabilities include cross site scripting vulnerabilities and information disclosure vulnerabilities.
Status: Apple confirmed, updates available. Users can mitigate the impact of the Bluetooth vulnerability by disabling Bluetooth access, though this will impact normal functionality.
Description: AOL Instant Messenger (AIM) is AOL's popular instant messenging application. AIM allows users to send messages with embedded HTML. These messages are rendered using Microsoft's HTML rendering engine. Embedded HTML and scripting code in messages will be executed as though it had been viewed in Microsoft Internet Explorer. Therefore, any vulnerabilities exploitable in Microsoft Internet Explorer are exploitable in AIM, including vulnerabilities involving ActiveX control instantiation. No user interaction is required to exploit this vulnerability if the user is configured to accept messages from unknown recipients. A simple proof-of-concept and full technical details are available for this vulnerability.
Status: AOL confirmed, updates available.
Description: The Ask Toolbar provides Microsoft Internet Explorer users easy access to Ask.com services. This toolbar is implemented as an ActiveX control. This control contains a buffer overflow vulnerability in its "ShortForm" member. A specially crafted web page that instantiates this control could trigger this vulnerability and execute arbitrary code with the privileges of the current user. A proof-of-concept for this vulnerability is publicly available.
Status: Ask has not confirmed, no updates available. Users can mitigate the impact of this vulnerability by disabling the affected control via Microsoft's "kill bit" mechanism.
Description: Microsoft Internet Explorer is vulnerable to an arbitrary file upload attack. A web page containing a specially crafted HTML form could exploit this vulnerability to disclose the contents of any file on the system to an attacker with the privileges of the current user. A proof-of-concept and full technical details are available for this vulnerability.
Status: Microsoft has not confirmed, no updates available.
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 5549 unique vulnerabilities. For this special SANS community listing, Qualys also includes vulnerabilities that cannot be scanned remotely.
