Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection')
A vulnerability in the local management CLI implementation for specific commands on the Cisco UCS B-Series Blade Servers could allow an authenticated, local attacker to overwrite an arbitrary file on disk. It is also possible the attacker could inject CLI command parameters that should not be allowed for a specific subset of local management CLI commands. The vulnerability is due to lack of proper input validation of user input for local management CLI commands. An attacker could exploit this vulnerability by authenticating to the device and issuing a crafted form of a limited subset of local management CLI commands. An exploit could allow the attacker to overwrite an arbitrary files on disk or inject CLI command parameters that should have been disabled. This vulnerability is fixed in software version 4.0(2a) and later.
CWE-78 - OS Command Injection
The OS command injection weakness (also known as shell injection) is a vulnerability which enables an attacker to run arbitrary OS commands on a server. This is done by modifying the intended downstream OS command and injecting arbitrary commands, enabling the execution of unauthorized OS commands. This has the potential to fully compromise the application along with all of its data, and, if the compromised process does not follow the principle of least privileges, it may compromise other parts of the hosting infrastructure as well. This weakness is listed as number ten in the 'CWE Top 25 Most Dangerous Software Weaknesses'.
