The attacker would need to have access to the internal VLAN where CPS is deployed. The vulnerability is due to lack of authentication. An attacker could exploit this vulnerability by directly connecting to the Graphite web interface. An exploit could allow the attacker to access various statistics and Key Performance Indicators (KPIs) regarding the Cisco Policy Suite environment. 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-20190109-cps-graphite-access Affected Products o Vulnerable Products This vulnerability affects Cisco Policy Suite. 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.

The vulnerability is due to improper authentication when accessing the Redis server. An unauthenticated attacker could exploit this vulnerability by modifying key-value pairs stored within the Redis server database. An exploit could allow the attacker to reduce the efficiency of the Cisco Policy Suite for Mobile and Cisco Policy Suite Diameter Routing Agent software. Cisco has released software updates that address this vulnerability for Cisco Policy Suite for Mobile. Currently there is no software release available for Cisco Policy Suite Diameter Routing Agent software. There are no workarounds that address this vulnerability, but a mitigation for Cisco Policy Suite Diameter Routing Agent software exists. See the Workarounds section for more details. This advisory is available at the following link: https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190109-cps-redis Affected Products o Vulnerable Products This vulnerability affects the following Cisco products running a vulnerable software version: - Cisco Policy Suite for Mobile - Cisco Policy Suite Diameter Routing Agent For information about affected software releases, consult the Cisco bug IDs at the top of this advisory. Products Confirmed Not Vulnerable Cisco has confirmed that this vulnerability does not affect the following products: - Cisco Policy Suite for BNG - Cisco Policy Suite for Wi-Fi 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. A mitigation for Cisco Policy Suite Diameter Routing Agent software exists that reduces the attack surface by blocking access to external facing interfaces. This procedure requires a number of steps to complete. Contact the Cisco Technical Assistance Center (TAC) for details and assistance in implementation.
