Cisco Multiple Vulnerabilities

Speak With A Security Expert Now

THE THREAT

On April 7th, 2021, Cisco announced two high rated and one critical vulnerability impacting the Cisco SD-WAN vManage Software. vManage software is used to centralize network management.

CVE-2021-1137 and CVE-2021-1480 (CVSS:7.8) are Privilege Escalation vulnerabilities that could be used by a previously authenticated actor to gain root privileges on the underlying operating system. More concerning is CVE-2021-1479 (CVSS:9.8); a Buffer Overflow vulnerability that allows an unauthenticated remote actor to execute code with root privileges on the underlying operating system.

While exploitation in the wild has not been identified at this time, the high criticality rating for CVE-2021-1479 is likely to draw attention from both researchers and threat actors. Organizations are strongly recommended to apply the relevant security patches as soon as possible.
