Security Advisory

This security advisory describes one critical risk vulnerability.

1) Improper input validation

Severity: Critical

CVSSv3: 9.5 [CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H/E:H/RL:O/RC:C] [PCI]

CVE-ID: CVE-2017-3881

CWE-ID: CWE-20 - Improper Input Validation

Description

The vulnerability allows a remote attacker to gain access to vulnerable device.

The vulnerability exists due to improper input validation in Cisco Cluster Management Protocol (CMP) implementation and failure to restrict usage of CMP-specific Telnet options only to internal, local communications between cluster members. A remote unauthenticated attacker can send specially crafted CMP-specific Telnet options while establishing a Telnet session with an affected Cisco device configured to accept Telnet connections and cause the affected device to reload or obtain full control over vulnerable device.

Successful exploitation of this vulnerability may allow an attacker to gain full access to vulnerable device.

Note: information about this vulnerability was publicly disclosed by WikiLeaks documents dubbed CIA Vault 7.
