The Windows interactive service in OpenVPN 2.7_alpha1 through 2.7.4 allows remote attackers to cause persistent DNS state pollution or a service crash via a crafted search domain during the disconnection process
AI Analysis
Technical Summary
The Windows interactive service component in OpenVPN versions 2.7_alpha1 through 2.7.4 is vulnerable to remote attacks that can manipulate DNS state persistently or cause the service to crash. This occurs when a specially crafted search domain is processed during the VPN disconnection phase. The vulnerability is identified as CWE-125 (Out-of-bounds Read). No patch or official remediation information is currently provided. There are no known exploits in the wild at this time.
Potential Impact
Successful exploitation can lead to persistent corruption of DNS state on the affected system or cause the OpenVPN service to crash, potentially disrupting VPN connectivity and related network operations.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, consider limiting exposure of the affected OpenVPN service to untrusted networks and monitor for unusual DNS or service behavior.
