CVE-2026-107782

Summary

The vulnerability allows local attackers to bypass authorization checks in System Informer's helper service, enabling them to execute arbitrary code with SYSTEM privileges by connecting from any Authenticode-signed process. This creates a privilege escalation vector where attackers can load malicious code into Microsoft-signed processes like rundll32.exe and call privileged APIs.

Exploitability

Exploitation is moderately easy requiring only a local attacker with access to an Authenticode-signed process, as the vulnerability allows direct API calls to the privileged service without proper authentication checks.

Blast radius

The impact could be significant as local attackers can escalate privileges to SYSTEM level, potentially allowing full system compromise through code execution in high-privilege processes.

Detection

No reliable host or network indicator is derivable from the published description.

Prioritized remediation

Upgrade to System Informer version 4.0.26241.138 or later
