The vulnerability is due to insufficient validation of user-provided input. An attacker could exploit this vulnerability by logging in with a highly privileged user account and performing a sequence of specific user management operations that interfere with the underlying operating system. A successful exploit could allow the attacker to permanently degrade the functionality of the affected system. There are no workarounds that address this vulnerability. This advisory is available at the following link: https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/ cisco-sa-20180905-nfvis-dos1 Affected Products o Vulnerable Products This vulnerability affects Cisco Enterprise NFV Infrastructure Software (NFVIS). For information about affected software releases, consult the Cisco bug ID(s) at the top of this advisory. Products Confirmed Not Vulnerable Only products listed in the Vulnerable Products section of this advisory are known to be affected by this vulnerability. Workarounds o There are no workarounds that address this vulnerability. Fixed Software o For information about fixed software releases, consult the Cisco bug ID(s) at the top of this advisory. When considering software upgrades, customers are advised to regularly consult the advisories for Cisco products, which are available from the Cisco Security Advisories and Alerts page, to determine exposure and a complete upgrade solution. In all cases, customers should ensure that the devices to be upgraded contain sufficient memory and confirm that current hardware and software configurations will continue to be supported properly by the new release. If the information is not clear, customers are advised to contact the Cisco Technical Assistance Center (TAC) or their contracted maintenance providers. Exploitation and Public Announcements o The Cisco Product Security Incident Response Team (PSIRT) is not aware of any public announcements or malicious use of the vulnerability that is described in this advisory. Source o Cisco would like to thank the Security Teams of Orange Group for reporting this vulnerability.

The vulnerability is due to insufficient server-side authorization checks. An attacker who is logged in to the web-based management interface as a low-privileged user could exploit this vulnerability by sending a crafted HTTP request. A successful exploit could allow the attacker to use the low-privileged user account to reboot or shut down the affected system. There are no workarounds that address this vulnerability.
