SoftEtherVPN is a an open-source cross-platform multi-protocol VPN Program. Versions 5.02.5184 to 5.02.5187 are vulnerable to NULL dereference in `DeleteIPv6DefaultRouterInRA` called by `StorePacket`. Before dereferencing, `DeleteIPv6DefaultRouterInRA` does not account for `ParsePacket` returning NULL, resulting in the program crashing. A patched version does not exist at this time.

OpenVPN Connect before version 3.5.0 can contain the configuration profile's clear-text private key which is logged in the application log, which an unauthorized actor can use to decrypt the VPN traffic

SoftEtherVPN is a an open-source cross-platform multi-protocol VPN Program. When SoftEtherVPN is deployed with L2TP enabled on a device, it introduces the possibility of the host being used for amplification/reflection traffic generation because it will respond to every packet with two response packets that are larger than the request packet size. These sorts of techniques are used by external actors who generate spoofed source IPs to target a destination on the internet. This vulnerability has been patched in version 5.02.5185.

Reposilite is an open source, lightweight and easy-to-use repository manager for Maven based artifacts in JVM ecosystem. As a Maven repository manager, Reposilite provides the ability to view the artifacts content in the browser, as well as perform administrative tasks via API. The problem lies in the fact that the artifact's content is served via the same origin (protocol/host/port) as the Admin UI. If the artifact contains HTML content with javascript inside, the javascript is executed within the same origin. Therefore, if an authenticated user is viewing the artifacts content, the javascript inside can access the browser's local storage where the user's password (aka 'token-secret') is stored. It is especially dangerous in scenarios where Reposilite is configured to mirror third party repositories, like the Maven Central Repository. Since anyone can publish an artifact to Maven Central under its own name, such malicious packages can be used to attack the Reposilite instance. This issue may lead to the full Reposilite instance compromise. If this attack is performed against the admin user, it's possible to use the admin API to modify settings and artifacts on the instance. In the worst case scenario, an attacker would be able to obtain the Remote code execution on all systems that use artifacts from Reposilite. It's important to note that the attacker does not need to lure a victim user to use a malicious artifact, but just open a link in the browser. This link can be silently loaded among the other HTML content, making this attack unnoticeable. Even if the Reposilite instance is located in an isolated environment, such as behind a VPN or in the local network, this attack is still possible as it can be performed from the admin browser. Reposilite has addressed this issue in version 3.5.12. Users are advised to upgrade. There are no known workarounds for this vulnerability. This issue was discovered and reported by the GitHub Security lab and is also tracked as GHSL-2024-072.

The installer (aka openvpn-client-installer) in Securepoint SSL VPN Client before 2.0.40 allows local privilege escalation during installation or repair.

ASUS router RT-AX88U has a vulnerability of using externally controllable format strings within its Advanced Open VPN function. An authenticated remote attacker can exploit the exported OpenVPN configuration to execute an externally-controlled format string attack, resulting in sensitivity information leakage, or forcing the device to reset and permanent denial of service.

An issue was discovered in Stormshield SSL VPN Client before 3.2.0. A logged-in user, able to only launch the VPNSSL Client, can use the OpenVPN instance to execute malicious code as administrator on the local machine.

Teltonika’s Remote Management System versions prior to 4.10.0 contain a virtual private network (VPN) hub feature for cross-device communication that uses OpenVPN. It connects new devices in a manner that allows the new device to communicate with all Teltonika devices connected to the VPN. The OpenVPN server also allows users to route through it. An attacker could route a connection to a remote server through the OpenVPN server, enabling them to scan and access data from other Teltonika devices connected to the VPN.

Mozilla VPN can load an OpenSSL configuration file from an unsecured directory. A user or attacker with limited privileges could leverage this to launch arbitrary code with SYSTEM privilege. This vulnerability affects Mozilla VPN < 2.7.1.

The iTopVPNmini.exe component of iTop VPN 3.2 will try to connect to datastate_iTopVPN_Pipe_Server on a loop. An attacker that opened a named pipe with the same name can use it to gain the token of another user by listening for connections and abusing ImpersonateNamedPipeClient().

An issue was discovered in Amazon AWS VPN Client 2.0.0. It is possible to include a UNC path in the OpenVPN configuration file when referencing file paths for parameters (such as auth-user-pass). When this file is imported and the client attempts to validate the file path, it performs an open operation on the path and leaks the user's Net-NTLMv2 hash to an external server. This could be exploited by having a user open a crafted malicious ovpn configuration file.

GlobalProtect-openconnect versions prior to 2.0.0 (exclusive) are affected by incorrect access control in GPService through DBUS, GUI. The way GlobalProtect-Openconnect is set up enables arbitrary users to start a VPN connection to arbitrary servers. By hosting an openconnect compatible server, the attack can redirect the entire host's traffic via their own server.

Gryphon Tower routers contain an unprotected openvpn configuration file which can grant attackers access to the Gryphon homebound VPN network which exposes the LAN interfaces of other users' devices connected to the same service. An attacker could leverage this to make configuration changes to, or otherwise attack victims' devices as though they were on an adjacent network.

Securepoint SSL VPN Client v2 before 2.0.32 on Windows has unsafe configuration handling that enables local privilege escalation to NT AUTHORITY\SYSTEM. A non-privileged local user can modify the OpenVPN configuration stored under "%APPDATA%\Securepoint SSL VPN" and add a external script file that is executed as privileged user.

All versions of Windscribe VPN for Mac and Windows <= v2.02.10 contain a local privilege escalation vulnerability in the WindscribeService component. A low privilege user could leverage several openvpn options to execute code as root/SYSTEM.

A vulnerability in the Private Internet Access (PIA) VPN Client for Linux 1.5 through 2.3+ allows remote attackers to bypass an intended VPN kill switch mechanism and read sensitive information via intercepting network traffic. Since 1.5, PIA has supported a “split tunnel” OpenVPN bypass option. The PIA killswitch & associated iptables firewall is designed to protect you while using the Internet. When the kill switch is configured to block all inbound and outbound network traffic, privileged applications can continue sending & receiving network traffic if net.ipv4.ip_forward has been enabled in the system kernel parameters. For example, a Docker container running on a host with the VPN turned off, and the kill switch turned on, can continue using the internet, leaking the host IP (CWE 200). In PIA 2.4.0+, policy-based routing is enabled by default and is used to direct all forwarded packets to the VPN interface automatically.

An Elevation of Privilege issue was discovered in Aviatrix VPN Client before 2.10.7, because of an incomplete fix for CVE-2020-7224. This affects Linux, macOS, and Windows installations for certain OpenSSL parameters.

Grandstream GXP1600 series firmware 1.0.4.152 and below is vulnerable to authenticated remote command execution when an attacker adds an OpenVPN up script to the phone's VPN settings via the "Additional Settings" field in the web interface. When the VPN's connection is established, the user defined script is executed with root privileges.

An issue was discovered in Open Network Operating System (ONOS) 1.14. In the Ethernet VPN application (org.onosproject.evpnopenflow), the host event listener does not handle the following event types: HOST_MOVED, HOST_UPDATED. In combination with other applications, this could lead to the absence of intended code execution.

OpenConnect VPN client with GnuTLS before 5.02 contains a heap overflow if MTU is increased on reconnection.
