CVE-2018-0089

CWE-264

Summary

A vulnerability in the Policy and Charging Rules Function (PCRF) of the Cisco
Policy Suite (CPS) could allow an unauthenticated, remote attacker to access 
sensitive data. The attacker could use this information to conduct additional
reconnaissance attacks. The attacker would also have to have access to the 
internal VLAN where CPS is deployed.

The vulnerability is due to incorrect permissions of certain system files and
not sufficiently protecting sensitive data that is at rest. An attacker could
exploit the vulnerability by using certain tools available on the internal 
network interface to request and view system files. An exploit could allow the
attacker to find out sensitive information about the application.

There are no workarounds that address this vulnerability.
