A local privilege escalation vulnerability in Slate Digital Connect on macOS allows attackers to gain elevated privileges through a manipulated XPC service.

The XPC Service fails to correctly follow the certificate chain of trust. A local attacker can exploit this by signing a malicious client with a self-signed certificate, tricking the service into granting elevated permissions.

With a CVSS score of 8.4, this vulnerability presents a significant risk to the security of affected macOS workstations. While exploitation requires local access, successful execution allows an attacker to achieve privilege escalation, potentially leading to full system compromise or persistence on the affected machine.

Immediate Action: Consult the official Slate Digital advisory for the availability of a security update or patch to resolve the XPC service validation flaw.

Proactive Monitoring: Review macOS system logs for suspicious XPC connection attempts or unexpected process execution patterns involving Slate Digital Connect.

Compensating Controls: Ensure that macOS system integrity protections are enabled and restrict local user account permissions to minimize the impact of potential privilege escalation.

Public Exploit Available: False

Although exploitation requires local access, the high severity of potential privilege escalation warrants immediate attention. Users should monitor the Slate Digital support portal for patch releases and apply them as soon as they become available to mitigate the risk of local system compromise.
