New TunnelVision Attack Allows Hijacking of VPN Traffic via DHCP Manipulation

Researchers have detailed a Virtual Private Network VPN bypass technique dubbed TunnelVision that allows threat actors to snoop on victim's network traffic by just being on the same local network. The "decloaking" method has been assigned the CVE identifier CVE-2024-3661 CVSS score: 7.6. It impac...

K000139553: VPN TunnelVision vulnerability CVE-2024-3661

Security Advisory Description By design, the DHCP protocol does not authenticate messages, including for example the classless static route option 121. An attacker with the ability to send DHCP messages can manipulate routes to redirect VPN traffic, allowing the attacker to read, disrupt, or...

SUSE CVE-2022-48687

In the Linux kernel, the following vulnerability has been resolved: ipv6: sr: fix out-of-bounds read when setting HMAC data. The SRv6 layer allows defining HMAC data that can later be used to sign IPv6 Segment Routing Headers. This configuration is realised via netlink through four attributes:...

The vulnerability of the Daemon Routing Protocols (RPD) in Juniper Networks’ Junos OS and Junos OS Evolved operating systems allows a attacker to cause service interruptions.

The vulnerability of the Demon Routing Protocols Daemon RPD in Juniper Networks’ Junos OS and Junos OS Evolved operating systems is related to insufficient handling of exceptional states during packet forwarding based on the Class-of-Service CoS-based forwarding mechanism. Exploiting this...

CVE-2024-3661 DHCP routing options can manipulate interface-based VPN traffic

DHCP can add routes to a client’s routing table via the classless static route option 121. VPN-based security solutions that rely on routes to redirect traffic can be forced to leak traffic over the physical interface. An attacker on the same local network can read, disrupt, or possibly modify...

Why Your VPN May Not Be As Secure As It Claims

Virtual private networking VPN companies market their services as a way to prevent anyone from snooping on your Internet usage. But new research suggests this is a dangerous assumption when connecting to a VPN via an untrusted network, because attackers on the same network could force a targets...

DHCP 安全漏洞

DHCP is a network infrastructure protocol. A security vulnerability exists in DHCP that stems from the ability to add routes to a client's routing table via the static routing option, where an attacker on the same local network can read, corrupt, or modify VPN-protected network traffic...
