Cisco Warns of Vulnerability in SD-WAN Offering

Cisco has released software updates to fix a vulnerability in its software-defined wide-area networking (SD-WAN) solution, a fast-growing segment of the software-centric networking transformation.

"A vulnerability in the vContainer of the Cisco SD-WAN Solution could allow an authenticated, remote attacker to cause a denial of service (DoS) condition and execute arbitrary code as the root user," warns an advisory posted Wednesday (Jan. 23).

The advisory concerns only Cisco vSmart Controller Software running a release of Cisco SD-WAN solution versions before Release 18.4.0.

The company released free software updates to fix the problem, which was discovered by Cisco during internal testing.

The advisory was published just about a week after Cisco placed SD-WAN among "The 5 Technologies that will Change Networking in 2019."

"SD-WAN has been a promised technology for years, but in 2019 it will be a major driver in how networks are built and re-built," Cisco's Anand Oswal said in a blog post. "In the coming year, SD-WAN network traffic will grow by 500 percent, and our research shows that more than half of business customers who don't currently use SD-WAN are going to make plans for its adoption."
