CVE-2018-0347
Description
A vulnerability in the Zero Touch Provisioning (ZTP) subsystem of the Cisco SD-WAN Solution could allow an authenticated, local attacker to inject arbitrary commands that are executed with root privileges. The vulnerability is due to insufficient input validation. An attacker could exploit this vulnerability by authenticating to the device and submitting malicious input to the affected parameter. The attacker must be authenticated to access the affected parameter. A successful exploit could allow an attacker to execute commands with root privileges. 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: vEdge 100 Series Routers, vEdge 1000 Series Routers, vEdge 2000 Series Routers, vEdge 5000 Series Routers. Cisco Bug IDs: CSCvi69906.
AI Insight
LLM-synthesized narrative grounded in this CVE's description and references.
Cisco SD-WAN Zero Touch Provisioning subsystem contains a command injection vulnerability allowing authenticated local attackers to execute arbitrary commands with root privileges on affected vEdge routers.
Vulnerability
The Zero Touch Provisioning (ZTP) subsystem of the Cisco SD-WAN Solution fails to properly validate user-supplied input, leading to a command injection vulnerability. An authenticated, local attacker can inject arbitrary commands that are executed with root privileges. This affects vEdge 100, 1000, 2000, and 5000 Series Routers running a release prior to 18.3.0. [1]
Exploitation
An attacker must have local authentication to the device and submit malicious input to the affected parameter within the ZTP subsystem. The attacker does not require network access beyond the local console or SSH session. The exploitation involves crafting input that bypasses input validation to inject operating system commands. [1]
Impact
Successful exploitation allows the attacker to execute arbitrary commands with root privileges, resulting in full compromise of the device. This includes the ability to read, modify, or delete sensitive data, install malware, or disrupt network operations. [1]
Mitigation
Cisco has released software updates to fix this vulnerability. The fixed release is version 18.3.0 and later. Customers should upgrade to the latest available release. No workarounds are mentioned in the advisory. [1]
