CVE-2018-0434: Cisco SD-WAN Solution Certificate Validation Vulnerability

A vulnerability in the Zero Touch Provisioning feature of the Cisco SD-WAN Solution could allow an unauthenticated, remote attacker to gain unauthorized access to sensitive data by using an invalid certificate. The vulnerability is due to insufficient certificate validation by the affected software. An attacker could exploit this vulnerability by supplying a crafted certificate to an affected device. A successful exploit could allow the attacker to conduct man-in-the-middle attacks to decrypt confidential information on user connections to the affected software.

Security readout for executives and security teams

Cisco SD-WAN Zero Touch Provisioning did not adequately validate certificates. An unauthenticated remote attacker could potentially intercept user connections and decrypt confidential information. This is a trust-path issue for organizations using the affected Cisco SD-WAN Solution. Exposure is limited to Cisco SD-WAN Solution deployments using the affected Zero Touch Provisioning feature. The provided sources do not identify exact affected versions, deployment prerequisites, or internet exposure conditions. Treat as a targeted infrastructure risk, not a confirmed emergency. Prioritize validation because compromise could expose confidential SD-WAN traffic, but the provided sources lack severity scoring, affected version detail, and active exploitation evidence. Mitigation focus: Review Cisco’s advisory for affected releases and fixed software guidance.; Inventory Cisco SD-WAN components using Zero Touch Provisioning.; Prioritize upgrades or mitigations for management and provisioning paths..

Improper Certificate Validation

Improper Certificate Validation represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
