Security News > 2021 > September > Cisco Patches Critical Authentication Bug With Public Exploit

Cisco has patched a near-max critical bug in its NFVIS software for which there's a publicly available proof-of-concept exploit.

On Wednesday, Cisco released patches for the flaw - an authentication bypass vulnerability in Enterprise NFV Infrastructure Software that's tracked as CVE-2021-34746.

Cisco Enterprise NFVIS is a Linux-based piece of infrastructure software that helps service providers and other customers to deploy virtualized network functions, such as virtual routers and firewalls, as well as WAN acceleration, on supported Cisco devices.

"An attacker could exploit this vulnerability by injecting parameters into an authentication request," Cisco explained in its security advisory.

A month ago, Cisco revealed that a remote code execution vulnerability in its Adaptive Security Device Manager Launcher that it disclosed in July was a zero-day bug that still hasn't been fixed.

" A successful exploit could allow the attacker to execute arbitrary code on the user's operating system with the level of privileges assigned to the ASDM Launcher," Cisco said.
