Description

A missing double-check feature in the WebGUI for CLI deactivation in Infinera G42
version R6.1.3 allows an authenticated administrator to make other
management interfaces unavailable via local and network interfaces. The CLI deactivation via the WebGUI does not only stop CLI interface but deactivates also Linux Shell, WebGUI and Physical Serial Console access. No
confirmation is asked at deactivation time. Loosing access to these services device administrators are at risk of completely loosing device control.

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.

Weaknesses

Insufficient Granularity of Access Control

The product implements access controls via a policy or other feature with the intention to disable or restrict accesses (reads and/or writes) to assets in a system from untrusted agents. However, implemented access controls lack required granularity, which renders the control policy too broad because it allows accesses from unauthorized agents to the security-sensitive assets.
