It’s that time of year again—the Cisco IOS Software Security Advisory Bundled Publication will go live in seven days. As a reminder, the Cisco Product Security Incident Response Team (PSIRT) releases bundles of Cisco IOS Software Security Advisories on the fourth Wednesday of March and September each calendar year. As is the case with the vast majority of our advisories, vulnerabilities scheduled for disclosure in these upcoming Security Advisories will normally have a Common Vulnerability Scoring System (CVSS) Base Score from 7.0 to 10.0.
To ensure you’re prepared for the upcoming publication, consider:
Creating a text file of all the Cisco IOS Software releases in your network
Assembling a simple list of Cisco IOS Software technologies and features you use
Noting your Cisco.com username and password
Locating the username and password for your Cisco IOS routers and switches
Ensuring network operation partners are prepared for the security advisory release

Cisco’s Cloud Web Security (CWS) service provides TRAC researchers with a constant fire hose of malicious insight and now that we are collaborating with Sourcefire’s Vulnerability Research Team (VRT) we have additional capabilities to quickly isolate and prioritize specific web exploit activity for further analysis. Thus when we were recently alerted to an aggressive Fiesta exploit pack (EP) campaign targeting our customers, we quickly compared notes and found that in addition to the typical Java exploits, this EP was also using a Microsoft Silverlight exploit. In the Cisco 2014 Annual Security Report (ASR) we discuss how 2013 was a banner year for Java exploits, and while updating Java should remain a top priority, Silverlight is certainly worth patching as threat actors continue to search for new application exploits to leverage in drive-by attacks.

Over the past 30 days this specific Fiesta campaign was blocked across more than 300 different companies. The attacker(s) used numerous dynamic DNS (DDNS) domains -- that resolved to six different IP addresses -- as exploit landing pages. The chart below depicts the distribution of hosts used in this attack across the most blocked DDNS base domains.
Many Cisco customers with an interest in product security are aware of our security advisories and other publications issued by our Product Security Incident Response Team (PSIRT). That awareness is probably more acute than usual following the recent Cisco IOS Software Security Advisory Bundled Publication on September 25. But many may not be aware of the reasoning behind why, when, and how Cisco airs its “dirty laundry.”
Our primary reason for disclosing vulnerabilities is to ensure customers are able to accurately assess, mitigate, and remediate the risk our vulnerabilities may pose to the security of their networks.
In order to deliver on that promise, Cisco has has made some fundamental and formative decisions that we’ve carried forward since our first security advisory in June 1995.
It’s that time of year again—consider this post your friendly T-7 notice to start preparing for the final Cisco IOS Software Security Advisory Bundled Publication of 2013! As a reminder, the Cisco Product Security Incident Response Team (PSIRT) releases bundles of Cisco IOS Software Security Advisories on the fourth Wednesday of March and September each calendar year. As is the case with the vast majority of our advisories, vulnerabilities scheduled for disclosure in these upcoming Security Advisories will normally have a Common Vulnerability Scoring System (CVSS) Base Score from 7.0 to 10.0. Cisco security publications that disclose vulnerabilities scoring lower than 7.0 are described in our Cisco Security Vulnerability Policy. Read More »
Network Solutions is a domain name registrar that manages over 6.6 million domains. As of July 16, 2013, the Network Solutions website is under a Distributed Denial of Service (DDoS) attack. Recently, Network Solutions has been a target for attackers; in a previous outage, domain name servers were redirected away from their proper IP addresses. This was reported to be a result of a server misconfiguration while Network Solutions was attempting to mitigate a DDoS attack. It is possible that the DDoS attacks are related.
According to isitdownrightnow.com, the Network Solutions site has been having issues for at least the last 24 hours.
