Description

Alpine Halo9 Improper Verification of Cryptographic Signature Vulnerability. This vulnerability allows physically present attackers to bypass signature validation mechanism on affected installations of Alpine Halo9 devices. Authentication is not required to exploit this vulnerability.

The specific flaw exists within the firmware metadata signature validation mechanism. The issue results from the lack of proper verification of a cryptographic signature. An attacker can leverage this in conjunction with other vulnerabilities to execute arbitrary code in the context of root.

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.
