Cisco Issues Security Advisory For Security Software
The alert warns of a buffer overflow vulnerability in the Cisco Security Agent (CSA) for Windows, with remote code execution as the possible outcome.
The SANS Internet Storm center is warning organizations using Cisco products that contain Cisco Security Agent (CSA) for Windows to patch the program immediately because the security software is insecure.
"Cisco [has] just released an advisory covering a buffer overflow vulnerability in the Cisco Security Agent (CSA) for Windows, with remote code execution as the possible outcome," said Daniel Wesemann, a handler at the Internet Storm Center, in an online post. "CSA is a 'personal firewall' style product, and usually deployed as a defense against exactly the sort of threat that the component itself is now vulnerable to."
Wesemann observes that in 2004, a vulnerability of this sort would probably lead to a flurry of worms. Currently, drive-by spyware installation is a more likely consequence. "The bottom line is still the same: If you are using the vulnerable component, patch as soon as possible," he said.
In a security advisory issued on Wednesday, Cisco warned that the buffer overflow vulnerability could be exploited to "causes corruption of kernel memory, which leads to a Windows stop error (blue screen) or to arbitrary code execution."
According to Cisco, the vulnerability could be triggered using a maliciously crafted TCP segment sent to TCP port 139 or 445, which are used by the Microsoft Server Message Block (SMB) protocol.
Also on Thursday, Cisco introduced a new software architecture that combines identity and role-based security, which is intended to be implemented across enterprise networks.
The software, called Cisco Trusted Security or TrustSec, can be deployed enterprise-wide and utilized to authenticate users, assign roles, and enforce policies on networks comprised of Cisco's switches, routers, and Unified Wireless Network controllers.
2014 Next-Gen WAN SurveyWhile 68% say demand for WAN bandwidth will increase, just 15% are in the process of bringing new services or more capacity online now. For 26%, cost is the problem. Enter vendors from Aryaka to Cisco to Pertino, all looking to use cloud to transform how IT delivers wide-area connectivity.
The UC Infrastructure TrapWorries about subpar networks tanking unified communications programs could be valid: Thirty-one percent of respondents have rolled capabilities out to less than 10% of users vs. 21% delivering UC to 76% or more. Is low uptake a result of strained infrastructures delivering poor performance?
