Description

An authenticated remote code execution vulnerability exists in the AOS-8 and AOS-10 web-based management interface. A vulnerability in the certificate download functionality could allow an authenticated remote attacker to overwrite arbitrary files on the underlying operating system by exploiting improper input validation in the file path parameter. Successful exploitation could allow the attacker to execute arbitrary commands on the underlying operating system as a privileged user.

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

Improper Following of a Certificate's Chain of Trust

The product does not follow, or incorrectly follows, the chain of trust for a certificate back to a trusted root certificate, resulting in incorrect trust of any resource that is associated with that certificate. Learn more on MITRE.
