| OpenVPN version 2.6.1 through 2.6.13 in server mode using TLS-crypt-v2 allows remote attackers to trigger a denial of service by corrupting and replaying network packets in the early handshake phase | |||||
| CVE-2023-7235 | 1 Openvpn | 1 Openvpn Gui | 2025-05-06 | N/A | N/A |
| The OpenVPN GUI installer before version 2.6.9 did not set the proper access control restrictions to the installation directory of OpenVPN binaries when using a non-standard installation path, which allows an attacker to replace binaries to run arbitrary executables. | |||||
| CVE-2024-4877 | 2 Microsoft, Openvpn | 2 Windows, Openvpn | 2025-04-29 | N/A | N/A |
| OpenVPN version 2.4.0 through 2.6.10 on Windows allows an external, lesser privileged process to create a named pipe which the OpenVPN GUI component would connect to allowing it to escalate its privileges | |||||
| CVE-2022-0547 | 3 Debian, Fedoraproject, Openvpn | 3 Debian Linux, Fedora, Openvpn | 2025-04-23 | 7.5 HIGH | 9.8 CRITICAL |
| OpenVPN 2.1 until v2.4.12 and v2.5.6 may enable authentication bypass in external authentication plug-ins when more than one of them makes use of deferred authentication replies, which allows an external user to be granted access with only partially correct credentials. | |||||
| CVE-2023-7245 | 1 Openvpn | 1 Connect | 2025-04-02 | N/A | N/A |
| The nodejs framework in OpenVPN Connect 3.0 through 3.4.3 (Windows)/3.4.7 (macOS) was not properly configured, which allows a local user to execute arbitrary code within the nodejs process context via the ELECTRON_RUN_AS_NODE environment variable | |||||
| CVE-2020-20813 | 1 Openvpn | 1 Openvpn | 2024-10-07 | N/A | 7.5 HIGH |
| Control Channel in OpenVPN 2.4.7 and earlier allows remote attackers to cause a denial of service via crafted reset packet. | |||||
| CVE-2023-7224 | 1 Openvpn | 1 Connect | 2024-09-04 | N/A | 7.8 HIGH |
| OpenVPN Connect version 3.0 through 3.4.6 on macOS allows local users to execute code in external third party libraries using the DYLD_INSERT_LIBRARIES environment variable | |||||
| CVE-2024-27459 | 1 Openvpn | 1 Openvpn | 2024-08-23 | N/A | 7.8 HIGH |
| The interactive service in OpenVPN 2.6.9 and earlier allows an attacker to send data causing a stack overflow which can be used to execute arbitrary code with more privileges. | |||||
| CVE-2018-7544 | 1 Openvpn | 1 Openvpn | 2024-08-05 | 6.4 MEDIUM | 9.1 CRITICAL |
| A cross-protocol scripting issue was discovered in the management interface in OpenVPN through 2.4.5. When this interface is enabled over TCP without a password, and when no other clients are connected to this interface, attackers can execute arbitrary management commands, obtain sensitive information, or cause a denial of service (SIGTERM) by triggering XMLHttpRequest actions in a web browser. This is demonstrated by a multipart/form-data POST to http://localhost:23000 with a "signal SIGTERM" command in a TEXTAREA element. NOTE: The vendor disputes that this is a vulnerability. They state that this is the result of improper configuration of the OpenVPN instance rather than an intrinsic vulnerability, and now more explicitly warn against such configurations in both the management-interface documentation, and with a runtime warning | |||||
| CVE-2024-24974 | 1 Openvpn | 1 Openvpn | 2024-08-01 | N/A | 7.5 HIGH |
| The interactive service in OpenVPN 2.6.9 and earlier allows the OpenVPN service pipe to be accessed remotely, which allows a remote attacker to interact with the privileged OpenVPN interactive service. | |||||
| CVE-2024-27903 | 1 Openvpn | 1 Openvpn | 2024-07-11 | N/A | 9.8 CRITICAL |
| OpenVPN plug-ins on Windows with OpenVPN 2.6.9 and earlier could be loaded from any directory, which allows an attacker to load an arbitrary plug-in which can be used to interact with the privileged OpenVPN interactive service. | |||||
| CVE-2023-46850 | 3 Debian, Fedoraproject, Openvpn | 4 Debian Linux, Fedora, Openvpn and 1 more | 2023-11-29 | N/A | 9.8 CRITICAL |
| Use after free in OpenVPN version 2.6.0 to 2.6.6 may lead to undefined behavoir, leaking memory buffers or remote execution when sending network buffers to a remote peer. | |||||
| CVE-2020-15078 | 4 Canonical, Debian, Fedoraproject and 1 more | 4 Ubuntu Linux, Debian Linux, Fedora and 1 more | 2023-11-07 | 5.0 MEDIUM | 7.5 HIGH |
| OpenVPN 2.5.1 and earlier versions allows a remote attackers to bypass authentication and access control channel data on servers configured with deferred authentication, which can be used to potentially trigger further information leaks. | |||||
| CVE-2020-11810 | 3 Debian, Fedoraproject, Openvpn | 3 Debian Linux, Fedora, Openvpn | 2023-11-07 | 4.3 MEDIUM | 3.7 LOW |
| An issue was discovered in OpenVPN 2.4.x before 2.4.9. An attacker can inject a data channel v2 (P_DATA_V2) packet using a victim's peer-id. Normally such packets are dropped, but if this packet arrives before the data channel crypto parameters have been initialized, the victim's connection will be dropped. This requires careful timing due to the small time window (usually within a few seconds) between the victim client connection starting and the server PUSH_REPLY response back to the client. This attack will only work if Negotiable Cipher Parameters (NCP) is in use. | |||||
