| CVE-2013-2061 | 2 Opensuse, Openvpn | 3 Opensuse, Openvpn, Openvpn Access Server | 2024-11-21 | 2.6 LOW | N/A |
| The openvpn_decrypt function in crypto.c in OpenVPN 2.3.0 and earlier, when running in UDP mode, allows remote attackers to obtain sensitive information via a timing attack involving an HMAC comparison function that does not run in constant time and a padding oracle attack on the CBC mode cipher. | |||||
| CVE-2008-3459 | 1 Openvpn | 1 Openvpn | 2024-11-21 | 7.6 HIGH | N/A |
| Unspecified vulnerability in OpenVPN 2.1-beta14 through 2.1-rc8, when running on non-Windows systems, allows remote servers to execute arbitrary commands via crafted (1) lladdr and (2) iproute configuration directives, probably related to shell metacharacters. | |||||
| CVE-2006-2229 | 1 Openvpn | 2 Openvpn, Openvpn Access Server | 2024-11-21 | 4.0 MEDIUM | N/A |
| OpenVPN 2.0.7 and earlier, when configured to use the --management option with an IP that is not 127.0.0.1, uses a cleartext password for TCP sessions to the management interface, which might allow remote attackers to view sensitive information or cause a denial of service. | |||||
| CVE-2006-1629 | 1 Openvpn | 2 Openvpn, Openvpn Access Server | 2024-11-21 | 9.0 HIGH | N/A |
| OpenVPN 2.0 through 2.0.5 allows remote malicious servers to execute arbitrary code on the client by using setenv with the LD_PRELOAD environment variable. | |||||
| CVE-2005-3409 | 1 Openvpn | 2 Openvpn, Openvpn Access Server | 2024-11-21 | 5.0 MEDIUM | N/A |
| OpenVPN 2.x before 2.0.4, when running in TCP mode, allows remote attackers to cause a denial of service (segmentation fault) by forcing the accept function call to return an error status, which leads to a null dereference in an exception handler. | |||||
| CVE-2005-3393 | 1 Openvpn | 2 Openvpn, Openvpn Access Server | 2024-11-21 | 7.5 HIGH | N/A |
| Format string vulnerability in the foreign_option function in options.c for OpenVPN 2.0.x allows remote clients to execute arbitrary code via format string specifiers in a push of the dhcp-option command option. | |||||
| CVE-2005-2534 | 1 Openvpn | 1 Openvpn | 2024-11-20 | 2.6 LOW | N/A |
| Race condition in OpenVPN before 2.0.1, when --duplicate-cn is not enabled, allows remote attackers to cause a denial of service (server crash) via simultaneous TCP connections from multiple clients that use the same client certificate. | |||||
| CVE-2005-2533 | 1 Openvpn | 1 Openvpn | 2024-11-20 | 2.1 LOW | N/A |
| OpenVPN before 2.0.1, when running in "dev tap" Ethernet bridging mode, allows remote authenticated clients to cause a denial of service (memory exhaustion) via a flood of packets with a large number of spoofed MAC addresses. | |||||
| CVE-2005-2532 | 1 Openvpn | 1 Openvpn | 2024-11-20 | 5.0 MEDIUM | N/A |
| OpenVPN before 2.0.1 does not properly flush the OpenSSL error queue when a packet can not be decrypted by the server, which allows remote authenticated attackers to cause a denial of service (client disconnection) via a large number of packets that can not be decrypted. | |||||
| CVE-2005-2531 | 1 Openvpn | 1 Openvpn | 2024-11-20 | 5.0 MEDIUM | N/A |
| OpenVPN before 2.0.1, when running with "verb 0" and without TLS authentication, does not properly flush the OpenSSL error queue when a client fails certificate authentication to the server and causes the error to be processed by the wrong client, which allows remote attackers to cause a denial of service (client disconnection) via a large number of failed authentication attempts. | |||||
| 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 |
| ** DISPUTED ** 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. | |||||

| 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. | |||||
