Cisco Issues Patches for 4 Critical Vulnerabilities in Cisco Policy Suite

Cisco’s Policy Suite for Mobile controls billing and access control for customer devices. Root access to this suite is concerning because of the breadth of user device access.

The latest batch of Cisco patches includes fixes for four critical vulnerabilities related to unauthenticated access and default credentials in the Cisco Policy Suite for the Cisco Mobility Services Engine. All four were discovered by internal security testing. In addition, nine high-severity vulnerabilities and 12 medium ones were patched in a variety of other Cisco platforms.

Analysis

Two of the vulnerabilities (CVE-2018-0376 and CVE-2018-0374) give unauthenticated access to the Policy Builder database and interface, respectively, allowing for unauthorized changes to take place. CVE-2018-0377 affects the Open Systems Gateway initiative (OSGi) interface of the Policy Builder Suite and allows the remote attacker to access or change any files that are accessible by the OSGi process. The last critical patch (CVE-2018-0375) involves default credentials in the Cluster Manager of the Suite giving the attacker remote root access.

These Cisco vulnerabilities received a CVSS v3.0 score of 9.8 out of 10, indicating a "critical" degree of severity.
