CWE-291

Reliance on IP Address for Authentication

Category: VariantCVE: 10
Description

The product uses an IP address for authentication.

Extended Description

IP addresses can be easily spoofed. Attackers can forge the source IP address of the packets they send, but response packets will return to the forged IP address. To see the response packets, the attacker has to sniff the traffic between the victim machine and the forged IP address. In order to accomplish the required sniffing, attackers typically attempt to locate themselves on the same subnet as the victim machine. Attackers may be able to circumvent this requirement by using source routing, but source routing is disabled across much of the Internet today. In summary, IP address verification can be a useful part of an authentication scheme, but it should not be the single factor required for authentication.

CRITICAL
CVE-2022-46415

DJI Spark 01.00.0900 allows remote attackers to prevent legitimate terminal connections by exhausting the DHCP IP address pool. To accomplish this, the attacker would first need to connect to the device's internal Wi-Fi network (e.g., by guessing the password). Then, the attacker would need to send many DHCP request packets.

CVE-2024-23309

The LevelOne WBR-6012 router with firmware R0.40e6 has an authentication bypass vulnerability in its web application due to reliance on client IP addresses for authentication. Attackers could spoof an IP address to gain unauthorized access without needing a session token.

CVE-2026-4252

A vulnerability was identified in Tenda AC8 16.03.50.11. Affected by this issue is the function check_is_ipv6 of the component IPv6 Handler. The manipulation leads to reliance on ip address for authentication. It is possible to initiate the attack remotely. The exploit is publicly available and might be used.

CVE-2025-34202

Vasion Print (formerly PrinterLogic) Virtual Appliance Host prior to 25.2.169 and Application prior to 25.2.1518 (VA and SaaS deployments) expose Docker internal networks in a way that allows an attacker on the same external L2 segment — or an attacker able to add routes using the appliance as a gateway — to reach container IPs directly. This grants access to internal services (HTTP APIs, Redis, MySQL, etc.) that are intended to be isolated inside the container network. Many of those services are accessible without authentication or are vulnerable to known exploitation chains. As a result, compromise of a single reachable endpoint or basic network access can enable lateral movement, remote code execution, data exfiltration, and full system compromise. This vulnerability has been identified by the vendor as: V-2025-003 — Insecure Access to Docker Instance from WAN.

CVE-2025-59101

Instead of typical session tokens or cookies, it is verified on a per-request basis if the originating IP address has once successfully logged in. As soon as an authentication request from a certain source IP is successful, the IP address is handled as authenticated. No other session information is stored. Therefore, it is possible to spoof the IP address of a logged-in user to gain access to the Access Manager web interface.

CVE-2026-3690

OpenClaw Canvas Authentication Bypass Vulnerability. This vulnerability allows remote attackers to bypass authentication on affected installations of OpenClaw. Authentication is not required to exploit this vulnerability. The specific flaw exists within the implementation of the the authentication function for canvas endpoints. The issue results from improper implementation of authentication. An attacker can leverage this vulnerability to bypass authentication on the system. Was ZDI-CAN-29311.
