Summary
A vulnerability in the CLI of Cisco FXOS Software could allow an authenticated, local attacker to read or write arbitrary files on the underlying operating system. This is due to insufficient input validation. An attacker could exploit this by including crafted arguments to a specific CLI command, allowing arbitrary file read or write.
Risk Assessment
An attacker with local access could access sensitive files or modify system configuration, potentially compromising data integrity and confidentiality. This could enable further attacks.
Recommendation
Apply Cisco updates for FXOS. Restrict CLI access and monitor commands executed by administrators.
