Description

This security bulletin contains information about 3 vulnerabilities.


1) Information disclosure (CVE-ID: CVE-2018-0460)

CWE-ID: CWE-200 - Exposure of sensitive information to an unauthorized actor

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a remote authenticated attacker to obtain potentially sensitive information.

The vulnerability exists in the REST API of Cisco Enterprise NFV Infrastructure Software (NFVIS) due to insufficient authorization and parameter validation checks. A remote attacker can send a malicious API request with the authentication credentials of a low-privileged user and read any file on the affected system.


2) Improper input validation (CVE-ID: CVE-2018-0462)

CWE-ID: CWE-20 - Improper input validation

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a remote administrative attacker to cause DoS condition.

The vulnerability exists in the user management functionality of Cisco Enterprise NFV Infrastructure Software (NFVIS) due to insufficient validation of user-provided input. A remote attacker can log in with a highly privileged user account, perform a sequence of specific user management operations that interfere with the underlying operating system and permanently degrade the functionality of the affected system.


3) Improper input validation (CVE-ID: CVE-2018-0459)

CWE-ID: CWE-20 - Improper input validation

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a remote administrative attacker to cause DoS condition.

The vulnerability exists in the web-based management interface of Cisco Enterprise NFV Infrastructure Software (NFVIS) due to insufficient server-side authorization checks. A remote attacker who is logged in to the web-based management interface as a low-privileged user can send a specially crafted HTTP request and use the low-privileged user account to reboot or shut down the affected system.
