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. Cisco Bug IDs: CSCvf77666.
The product stores sensitive information in cleartext within a resource that might be accessible to another control sphere.

Because the information is stored in cleartext (i.e., unencrypted), attackers could potentially read it. Even if the information is encoded in a way that is not human-readable, certain techniques could determine which encoding is being used, then decode the information. When organizations adopt cloud services, it can be easier for attackers to access the data from anywhere on the Internet. In some systems/environments such as cloud, the use of “double encryption” (at both the software and hardware layer) might be required, and the developer might be solely responsible for both layers, instead of shared responsibility with the administrator of the broader system/environment.
