Cisco SD-WAN Software Command Injection Vulnerability
Description
A vulnerability in the CLI of Cisco SD-WAN Software could allow an authenticated, local attacker to inject arbitrary commands to be executed with root-level privileges on the underlying operating system of an affected device. This vulnerability is due to insufficient input validation on certain CLI commands. An attacker could exploit this vulnerability by authenticating to an affected device and submitting crafted input to the CLI. The attacker must be authenticated as an administrative user to execute the affected commands. A successful exploit could allow the attacker to execute commands with root-level privileges.
AI Insight
LLM-synthesized narrative grounded in this CVE's description and references.
An authenticated local attacker can inject arbitrary commands as root via crafted CLI input in Cisco SD-WAN Software due to insufficient input validation.
Vulnerability
The vulnerability resides in the CLI of Cisco SD-WAN Software, affecting vBond Orchestrator, vEdge Cloud Routers, vEdge Routers, vManage, and vSmart Controller products. It is due to insufficient input validation on certain CLI commands, allowing injection of arbitrary commands. Affected versions are those running vulnerable releases of Cisco SD-WAN Software as detailed in the fixed software section of the advisory [1].
Exploitation
An attacker must first authenticate as an administrative user to the affected device. The attacker then submits specially crafted input to the CLI, exploiting the lack of input validation to inject arbitrary commands. No additional user interaction or network access beyond local CLI is required [1].
Impact
Successful exploitation allows the attacker to execute arbitrary commands with root-level privileges on the underlying operating system, resulting in full compromise of the device's confidentiality, integrity, and availability [1].
Mitigation
Cisco has released software updates to address this vulnerability. No workarounds are available. Users should upgrade to fixed software versions as specified in the Cisco Security Advisory [1].
