What it is
From the CVE record
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. This vulnerability affects the following Cisco products if they are running a release of the Cisco SD-WAN Solution prior to Release 18.3.0: vBond Orchestrator Software, vEdge 100 Series Routers, vEdge 1000 Series Routers, vEdge 2000 Series Routers, vEdge 5000 Series Routers, vEdge Cloud Router Platform, vManage Network Management Software, vSmart Controller Software. Cisco Bug IDs: CSCvi70003.

How it is reached
- Attack Vector LocalRequires local access to the vulnerable system (e.g. local login, malicious file)
- Attack Complexity LowNo special conditions — the attack can be reliably reproduced
- Privileges Required HighRequires admin or elevated privileges
- User Interaction NoneNo user interaction needed — fully automated exploitation
Scope
- Scope UnchangedImpact is limited to the vulnerable component itself
Impact if exploited
- Confidentiality HighTotal information disclosure — all data in the component is compromised
- Integrity HighTotal loss of integrity — attacker can modify any data in the component
- Availability HighTotal denial of service — the component is completely unavailable
