HighCVSS 7.8Exploitation Probability (EPSS)
Low risk39th percentile - higher than 39% of all known CVEs
Summary
A vulnerability in the CLI of Cisco FXOS and Cisco UCS Manager Software could allow an authenticated, local attacker to execute arbitrary commands on the underlying OS. The issue is due to insufficient input validation. An attacker could exploit this by including crafted arguments to specific commands. On Cisco UCS 6400 Series Fabric Interconnects, injected commands are executed with root privileges.
Risk Assessment
The attack can lead to unauthorized command execution, potentially compromising system integrity and exposing sensitive data.
Recommendation
Apply Cisco-provided updates for FXOS and UCS Manager software. Restrict CLI access to trusted administrators only.

Original NVD description (English source)
A vulnerability in the CLI of Cisco FXOS Software and Cisco UCS Manager Software could allow an authenticated, local attacker to execute arbitrary commands on the underlying operating system (OS). The vulnerability is due to insufficient input validation. An attacker could exploit this vulnerability by including crafted arguments to specific commands. A successful exploit could allow the attacker to execute arbitrary commands on the underlying OS with the privileges of the currently logged-in user for all affected platforms excluding Cisco UCS 6400 Series Fabric Interconnects. On Cisco UCS 6400 Series Fabric Interconnects, the injected commands are executed with root privileges.
