Cisco Policy Suite Graphite Unauthenticated Read-Only Access Vulnerability

Prioroity:          Medium
Advisory ID:        cisco-sa-20190109-cps-graphite-access
First Published:    2019 January 9 16:00 GMT
Version 1.0:        Final
Workarounds:        No workarounds available
Cisco Bug IDs:      CSCvc95415
CVE-2018-15466
CWE-284
CVSS Score:         Base 5.3
CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N/E:X/RL:X/RC:X

Summary

  o A vulnerability in the Graphite web interface of the Policy and Charging
    Rules Function (PCRF) of Cisco Policy Suite (CPS) could allow an
    unauthenticated, remote attacker to access the Graphite web interface. 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.

Cisco Policy Suite for Mobile and Cisco Policy Suite Diameter Routing Agent
Software Redis Server Unauthenticated Access Vulnerability

Priority:           Medium
Advisory ID:        cisco-sa-20190109-cps-redis
First Published:    2019 January 9 16:00 GMT

CVE-2018-0181

Summary

  o A vulnerability in the Redis implementation used by the Cisco Policy Suite
    for Mobile and Cisco Policy Suite Diameter Routing Agent software could
    allow an unauthenticated, remote attacker to modify key-value pairs for
    short-lived events stored by the Redis server.

    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.
