Cisco has released a  patch for a critical vulnerability in software used to control large virtual environments.

The weakness gets a 10 out of 10 severity score and is found in Cisco’s Elastic Services Controller (ESC), which the company describes as offering a single point of control to manage all aspects of Virtual Network Functions and offers capabilities such as VM and service monitoring, auto-recovery and dynamic scaling. With ESC users control the lifecycle all virtualized resources, whether using Cisco or third-party VNFs, Cisco stated.

This vulnerability affects Cisco ESC running Software Release 4.1, 4.2, 4.3 or 4.4 when the REST API is enabled. The REST API is not enabled by default, Cisco noted.  The vulnerability is fixed in Cisco Elastic Services Controller Release 4.5.

Cisco said the susceptibility was found during internal security testing and the company is not aware of any public announcements or malicious use of the vulnerability.

Cisco has released free software updates that address this vulnerability and suggests going here for the fix.

This announcement was Cisco’s second “critical” patch this month.  Last week Cisco said a vulnerability in its Cisco Nexus 9000 Series Application Centric Infrastructure (ACI) Mode data center switch that could let an attacker secretly access system resources.

That patch was part of some 40 security advisories issued last week.
