Official 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.

The underlying weakness: 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.
How developers prevent this class of flaw
- Ensure that proper certificate checking is included in the system design.
- Understand, and properly implement all checks necessary to ensure the integrity of certificate trust integrity.
- If certificate pinning is being used, ensure that all relevant properties of the certificate are fully validated before the certificate is pinned, including the full chain of trust.
