Official description
Slate Digital Connect 1.37.0 for macOS installs a privileged helper tool, com.slatedigital.connect.privileged.helper.tool, which exposes the XPC service com.slatedigital.connect.privileged.helper.tool2. The helper validates connecting XPC clients by checking only the subject.OU value of the client's signing certificate and does not verify that the certificate chains to a trusted code-signing authority. A local attacker can sign a malicious client with a self-signed certificate containing the expected organizational unit value and connect to the privileged XPC service. This allows unauthorized access to privileged helper functionality and may lead to local privilege escalation.

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.
