Cisco this week announced patches for tens of vulnerabilities across its product portfolio, including a critical severity issue impacting the SD-WAN vManage software.
Tracked as CVE-2021-1479 with a CVSS score of 9.8, the critical bug exists because of improper validation of user-supplied input and could allow an attacker to trigger a buffer overflow by sending a crafted connection request to the remote management component of SD-WAN vManage.
An attacker able to successfully exploit the security issue would “execute arbitrary code on the underlying operating system with root privileges,” Cisco explains.
The flaw was addressed alongside two high severity elevation of privilege vulnerabilities in SD-WAN vManage, each featuring a CVSS score of 7.8.
