| OpenVPN versions before 2.4.3 and before 2.3.17 are vulnerable to remote denial-of-service when receiving malformed IPv6 packet. | ||||
| CVE-2017-7522 | 1 Openvpn | 1 Openvpn | 2024-08-05 | N/A |

| OpenVPN versions before 2.4.3 and before 2.3.17 are vulnerable to remote denial-of-service due to memory exhaustion caused by memory leaks and double-free issue in extract_x509_extension(). | ||||
| CVE-2017-7520 | 1 Openvpn | 1 Openvpn | 2024-08-05 | N/A |
| OpenVPN versions before 2.4.3 and before 2.3.17 are vulnerable to denial-of-service and/or possibly sensitive memory leak triggered by man-in-the-middle attacker. | ||||
| CVE-2017-7478 | 1 Openvpn | 1 Openvpn | 2024-08-05 | N/A |
| OpenVPN version 2.3.12 and newer is vulnerable to unauthenticated Denial of Service of server via received large control packet. Note that this issue is fixed in 2.3.15 and 2.4.2. | ||||
| CVE-2017-7479 | 1 Openvpn | 1 Openvpn | 2024-08-05 | N/A |
| OpenVPN versions before 2.3.15 and before 2.4.2 are vulnerable to reachable assertion when packet-ID counter rolls over resulting into Denial of Service of server by authenticated attacker. | ||||
| CVE-2017-5868 | 1 Openvpn | 1 Openvpn Access Server | 2024-08-05 | N/A |
| CRLF injection vulnerability in the web interface in OpenVPN Access Server 2.1.4 allows remote attackers to inject arbitrary HTTP headers and consequently conduct session fixation attacks and possibly HTTP response splitting attacks via "%0A" characters in the PATH_INFO to __session_start__/. | ||||
| CVE-2018-9336 | 2 Openvpn, Slackware | 2 Openvpn, Slackware Linux | 2024-08-05 | N/A |
| openvpnserv.exe (aka the interactive service helper) in OpenVPN 2.4.x before 2.4.6 allows a local attacker to cause a double-free of memory by sending a malformed request to the interactive service. This could cause a denial-of-service through memory corruption or possibly have unspecified other impact including privilege escalation. | ||||
| CVE-2018-7544 | 1 Openvpn | 1 Openvpn | 2024-08-05 | N/A |
| 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-2020-36382 | 1 Openvpn | 1 Openvpn Access Server | 2024-08-04 | 7.5 High |
| OpenVPN Access Server 2.7.3 to 2.8.7 allows remote attackers to trigger an assert during the user authentication phase via incorrect authentication token data in an early phase of the user authentication resulting in a denial of service. | ||||
| CVE-2020-20813 | 1 Openvpn | 1 Openvpn | 2024-08-04 | 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-2020-15074 | 1 Openvpn | 1 Openvpn Access Server | 2024-08-04 | 7.5 High |
| OpenVPN Access Server older than version 2.8.4 and version 2.9.5 generates new user authentication tokens instead of reusing exiting tokens on reconnect making it possible to circumvent the initial token expiry timestamp. | ||||
| CVE-2020-15077 | 1 Openvpn | 1 Openvpn Access Server | 2024-08-04 | 5.3 Medium |
| OpenVPN Access Server 2.8.7 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-2020-15076 | 1 Openvpn | 1 Private Tunnel | 2024-08-04 | 7.8 High |
| Private Tunnel installer for macOS version 3.0.1 and older versions may corrupt system critical files it should not have access via symlinks in /tmp. | ||||
| CVE-2020-15078 | 4 Canonical, Debian, Fedoraproject and 1 more | 4 Ubuntu Linux, Debian Linux, Fedora and 1 more | 2024-08-04 | 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-2020-15075 | 1 Openvpn | 1 Connect | 2024-08-04 | 7.1 High |
| OpenVPN Connect installer for macOS version 3.2.6 and older may corrupt system critical files it should not have access via symlinks in /tmp. | ||||
| CVE-2020-11810 | 3 Debian, Fedoraproject, Openvpn | 3 Debian Linux, Fedora, Openvpn | 2024-08-04 | 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. | ||||
| CVE-2020-11462 | 1 Openvpn | 1 Openvpn Access Server | 2024-08-04 | 7.5 High |
| An issue was discovered in OpenVPN Access Server before 2.7.0 and 2.8.x before 2.8.3. With the full featured RPC2 interface enabled, it is possible to achieve a temporary DoS state of the management interface when sending an XML Entity Expansion (XEE) payload to the XMLRPC based RPC2 interface. The duration of the DoS state depends on available memory and CPU speed. The default restricted mode of the RPC2 interface is NOT vulnerable. | ||||
| CVE-2020-9442 | 2 Microsoft, Openvpn | 2 Windows, Connect | 2024-08-04 | 7.8 High |
| OpenVPN Connect 3.1.0.361 on Windows has Insecure Permissions for %PROGRAMDATA%\OpenVPN Connect\drivers\tap\amd64\win10, which allows local users to gain privileges by copying a malicious drvstore.dll there. | ||||
| CVE-2020-8953 | 1 Openvpn | 1 Openvpn Access Server | 2024-08-04 | 9.8 Critical |
| OpenVPN Access Server 2.8.x before 2.8.1 allows LDAP authentication bypass (except when a user is enrolled in two-factor authentication). | ||||
