Security News > 2021 > September > Patched: Critical bug with public PoC exploit in Cisco infrastructure virtualization software (CVE-2021-34746)
A critical vulnerability that affects Cisco Enterprise NFV Infrastructure Software has been patched and Cisco is urging enterprise admins to quickly upgrade to a fixed version, as proof-of-concept exploit code is already available.
The bug could be exploited by remote attackers to bypass authentication and log in to an affected device as an administrator.
"Linux-based infrastructure software designed to help service providers and enterprises to design, deploy and manage network services. Cisco Enterprise NFVIS helps dynamically deploy virtualized network functions, such as a virtual router, firewall, and WAN accelerator on supported Cisco devices," Cisco explains.
The vulnerability affects Cisco Enterprise NFVIS release 4.5.1, and has been fixed in releases 4.6.1 and later.
Even if proof-of-concept exploit code is available, there's no need for panic, as there is currently no evidence of the flaw being exploited by malicious actors.
To check whether your installation is vulnerable, follow the instructions provided by Cisco.
