HP OpenView flaws are extremely dangerous because of the access OpenView has to many systems. Don't let your network management folks talk you out of fixing them. Alan
@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: HP OpenView is a popular suite of network monitoring and management applications. It contains multiple vulnerabilities in a variety of Common Gateway Interface (CGI) components. These components are used to provide web interfaces to various parts of the application. A specially crafted web request to one of these vulnerable applications could trigger a buffer overflow vulnerability. Successfully exploiting this vulnerability would allow an attacker to execute arbitrary code with the privileges of the vulnerable process. Some technical details are publicly available for these vulnerabilities.
Status: Vendor confirmed, updates available.
Description: The ComponentOne SizerOne ActiveX control is a popular ActiveX control used to provide dynamic sizing of user interface elements, as well as tabbed user interface elements. It contains a buffer overflow in its handling of its "AddTab" method. A specially crafted web page that instantiated this control could trigger this buffer overflow, allowing an attacker to execute arbitrary code with the privileges of the vulnerable process. This ActiveX control is used in some popular software products, such as SAP and TSC2 Helpdesk.
Status: Vendor confirmed, updates available. Users can mitigate the impact of this vulnerability by disabling the affected control via Microsoft's "kill bit" mechanism. Note that this will affect common application functionality.
Description: Multiple Computer Associates products are reported to contain a remote command execution vulnerability due to insufficient authentication validation. A remote attacker could exploit this vulnerability to execute arbitrary commands with the privileges of the vulnerable process. Reportedly, no authentication is necessary to exploit this vulnerability. Few technical details are publicly available for this vulnerability.
Status: Vendor confirmed, updates available. Users are advised to restrict access to the vulnerable application at the network perimeter if possible.
Description: OpenSSL is an open source implementation of the Transport Layer Security (TLS, formerly the Secure Sockets Layer, SSL). It also provides general cryptographic services. It is widely used by both free and commercial software and used by default on a variety of operating systems, including most Unix and Linux-based systems. It contains a weakness in its verification of digital signatures and certificates, used by parties to verify their identity. A common use of digital certificates is to verify website authenticity. A specially crafted digital signature could bypass authentication, causing a vulnerable application to believe it is legitmate - for example, a malicious website could trick a web browser into believing that the site is something other than what it is. Full technical details are publicly available for this vulnerability. OpenSSL is the cryptographic framework used by web browsers such as Mozilla Firefox and Apple Safari, among others.
Status: Vendor confirmed, 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 6391 unique vulnerabilities. For this special SANS community listing, Qualys also includes vulnerabilities that cannot be scanned remotely.
