What is CVE-2021-1466?

A vulnerability in the vDaemon service associated with Cisco's SD-WAN vManage Software allows an authenticated local attacker to exploit a buffer overflow condition. This issue arises from incomplete bounds checks on the data provided to the vDaemon service. By sending specially crafted malicious data to the vDaemon listening service, an attacker can induce a failure in the service, leading to a denial of service (DoS) state. Cisco has issued software updates to remediate this vulnerability, and there are currently no alternative workarounds available.
