Cisco patches critical flaw in Prime Home device management server

The vulnerability could allow hackers to take over servers used by ISPs to manage subscribers and their gateway devices

Cisco Systems has fixed a critical vulnerability that could allow hackers to take over servers used by telecommunications providers to remotely manage customer equipment such as routers.

The vulnerability affects Cisco Prime Home, an automated configuration server (ACS) that communicates with subscriber devices using the TR-069 protocol. In addition to remotely managing customer equipment, it can also "automatically activate and configure subscribers and deliver advanced services via service packages" over mobile, fiber, cable, and other ISP networks.

"A vulnerability in the web-based GUI of Cisco Prime Home could allow an unauthenticated, remote attacker to bypass authentication and execute actions with administrator privileges," Cisco said in its advisory.

Attackers could exploit the vulnerability by sending API commands over HTTP to a particular URL without requiring authentication. The flaw is caused by a processing error in the role-based access control of URLs, Cisco explained.

In the past, security researchers found vulnerabilities in the TR-069 implementation of many routers that could have allowed hackers to remotely take over those devices. However, a vulnerability in an ACS like Cisco Prime Home is much worse, because it can be used to take control of entire groups of subscriber devices at once.

According to Cisco's documentation, the admin role on the Cisco Prime Home has access to the server's customer support, administration, and audit functions, as well as the ability to perform bulk operations and access utilities and reports.

The vulnerability affects Cisco Prime Home versions 6.3.0.0 and above. Customers are advised to migrate to the latest, fixed version: 6.5.0.1.

The company has also warned customers of a medium-risk URL redirect vulnerability in the Cisco Prime Service Catalog, a product that allows companies to set up self-service portals, provide IT service catalogs for data center and application services, and manage service requests.

An attacker could exploit the vulnerability to redirect a user logged into the Cisco Prime Service Catalog to a phishing site in order to steal their credentials.

A smarter way to print for busy small business owners, combining speedy printing with scanning and copying, making it easier to produce high quality documents and images at a touch of a button.

I've had a multifunction printer in the office going on 10 years now. It was a neat bit of kit back in the day -- print, copy, scan, fax -- when printing over WiFi felt a bit like magic. It’s seen better days though and an upgrade’s well overdue. This HP OfficeJet Pro 8730 looks like it ticks all the same boxes: print, copy, scan, and fax. (Really? Does anyone fax anything any more? I guess it's good to know the facility’s there, just in case.) Printing over WiFi is more-or- less standard these days.

I’d happily recommend this touchscreen laptop and Windows 10 as a great way to get serious work done at a desk or on the road.

Ultimately, I think the Windows 10 environment is excellent for me as it caters for so many different uses. The inclusion of the Xbox app is also great for when you need some downtime too!

For me, the Xbox Play Anywhere is a great new feature as it allows you to play your current Xbox games with higher resolutions and better graphics without forking out extra cash for another copy. Although available titles are still scarce, but I’m sure it will grow in time.
