Cisco SD-WAN Solution Command Injection Vulnerability
Description
A vulnerability in the command-line interface (CLI) in 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 crafted input to the CLI utility. The attacker must be authenticated to access the CLI utility. A successful exploit could allow the attacker to execute commands with root privileges.
AI Insight
LLM-synthesized narrative grounded in this CVE's description and references.
An authenticated, local attacker can inject arbitrary commands with root privileges on Cisco SD-WAN devices due to insufficient input validation in the CLI.
Vulnerability
The vulnerability exists in the CLI of Cisco SD-WAN Solution devices. Insufficient input validation allows an authenticated, local attacker to inject arbitrary commands. The affected versions are not explicitly enumerated in the available references, but the advisory [1] provides fixed release information.
Exploitation
An attacker must have local access and be authenticated to the device's CLI utility. They can then submit crafted input to the CLI, which is not properly validated, leading to command injection with root privileges.
Impact
Successful exploitation allows the attacker to execute arbitrary commands with root privileges on the affected device, resulting in full compromise of the device's confidentiality, integrity, and availability.
Mitigation
Cisco has released free software updates to address this vulnerability as noted in the Cisco Security Advisory [1]. Customers should upgrade to the fixed versions specified in the advisory. No workarounds are provided in the available references.
