CVE-2025-69783

OpenEDR Local Self‑Defense Bypass Leading to Privilege Escalation

A local attacker can bypass OpenEDR's 2.5.1.0 self-defense mechanism by renaming a malicious executable to match a trusted process name (e.g., csrss.exe, edrsvc.exe, edrcon.exe). This allows unauthorized interaction with the OpenEDR kernel driver, granting access to privileged functionality such as configuration changes, process monitoring, and IOCTL communication that should be restricted to trusted components. While this issue alone does not directly grant SYSTEM privileges, it breaks OpenEDR's trust model and enables further exploitation leading to full local privilege escalation.

CVE-2025-69784

Local Vulnerable IOCTL Enables DLL Injection for SYSTEM Privilege Escalation

A local, non-privileged attacker can abuse a vulnerable IOCTL interface exposed by the OpenEDR 2.5.1.0 kernel driver to modify the DLL injection path used by the product. By redirecting this path to a user-writable location, an attacker can cause OpenEDR to load an attacker-controlled DLL into high-privilege processes. This results in arbitrary code execution with SYSTEM privileges, leading to full compromise of the affected system.
