A vulnerability in the configuration and monitoring service of the Cisco SD-WAN Solution could allow an authenticated, local attacker to execute arbitrary code with root privileges or cause a denial of service (DoS) condition on an affected device.
The vulnerability is due to incomplete bounds checks for data that is provided by the configuration and monitoring service of the affected solution. An attacker could exploit this vulnerability by sending malicious data to the vDaemon listening service on an affected device. A successful exploit could allow the attacker to cause a buffer overflow condition on the affected device, which could allow the attacker to execute arbitrary code with root privileges on the device or cause the vDaemon listening service to reload and result in a DoS condition on the device.
There are no workarounds that address this vulnerability.
