Description
This security bulletin contains information about 2 secuirty vulnerabilities.
1) Command Injection (CVE-ID: CVE-2019-1893)
The vulnerability allows a local authenticated user to execute arbitrary code.
A vulnerability in Cisco Enterprise NFV Infrastructure Software (NFVIS) could allow an authenticated, local attacker to execute arbitrary commands on the underlying operating system (OS) of an affected device as root. The vulnerability is due to insufficient input validation of a configuration file that is accessible to a local shell user. An attacker could exploit this vulnerability by including malicious input during the execution of this file. A successful exploit could allow the attacker to execute arbitrary commands on the underlying OS as root.
2) Input validation error (CVE-ID: CVE-2019-1894)
The vulnerability allows a remote privileged user to execute arbitrary code.
A vulnerability in Cisco Enterprise NFV Infrastructure Software (NFVIS) could allow an authenticated, remote attacker with administrator privileges to overwrite or read arbitrary files on the underlying operating system (OS) of an affected device. The vulnerability is due to improper input validation in NFVIS filesystem commands. An attacker could exploit this vulnerability by using crafted variables during the execution of an affected command. A successful exploit could allow the attacker to overwrite or read arbitrary files on the underlying OS.
