CVE-2020-11810 (GCVE-0-2020-11810)
Vulnerability from nvd – Published: 2020-04-27 14:47 – Updated: 2024-08-04 11:42
VLAI
Summary
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.
Severity
No CVSS data available.

CVE-2018-9336 (GCVE-0-2018-9336)
Vulnerability from nvd – Published: 2018-05-01 18:00 – Updated: 2024-08-05 07:17
VLAI
Summary
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.
Severity
No CVSS data available.

CVE-2018-7544 (GCVE-0-2018-7544)
Vulnerability from nvd – Published: 2018-03-16 15:00 – Updated: 2024-11-14 20:46 Disputed
VLAI
Summary
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
