Two vulnerabilities in Cisco Enterprise NFV Infrastructure Software (NFVIS) could allow an authenticated, local attacker to read arbitrary files on the underlying operating system (OS) of an affected device.
The vulnerabilities are not dependent on one another; exploitation of one of the vulnerabilities is not required to exploit the other vulnerability. In addition, a software release that is affected by one of the vulnerabilities may not be affected by the other vulnerability.
Details about the vulnerabilities are as follows.Cisco Enterprise NFV Infrastructure Software Arbitrary File Read Vulnerability
A vulnerability in Cisco Enterprise NFV Infrastructure Software (NFVIS) could allow an authenticated, local attacker to read arbitrary files on the underlying operating system (OS) of an affected device.
The vulnerability is due to the improper input validation of arguments used with a vulnerable CLI command. An attacker could exploit this vulnerability by using a crafted argument during the execution of an affected command. A successful exploit could allow the attacker to read arbitrary files on the underlying OS.
The CVE ID for this vulnerability is: CVE-2019-1959
The bug ID for this vulnerability is: CSCvn12428
