CAPEC-4DetailedDraft
Using Alternative IP Address Encodings
This attack relies on the adversary using unexpected formats for representing IP addresses. Networked applications may expect network location information in a specific format, such as fully qualified domains names (FQDNs), URL, IP address, or IP Address ranges. If the location information is not validated against a variety of different possible encodings and formats, the adversary can use an alternate format to bypass application access control.

CVE-2025-34202Vasion 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-2024-23309The 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-2023-7211A vulnerability was found in Uniway Router 2.0. It has been declared as critical. This vulnerability affects unknown code of the component Administrative Web Interface. The manipulation leads to reliance on ip address for authentication. The attack can be initiated remotely. The complexity of an attack is rather high. The exploitation appears to be difficult. The exploit has been disclosed to the public and may be used. VDB-249766 is the identifier assigned to this vulnerability. NOTE: The vendor was contacted early about this disclosure but did not respond in any way.
CVE-2025-59101Instead 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-2023-35906IBM Aspera Faspex 5.0.5 could allow a remote attacked to bypass IP restrictions due to improper access controls. IBM X-Force ID: 259649.
CVE-2026-3690OpenClaw 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.
CVE-2025-66602A vulnerability has been found in FAST/TOOLS provided by Yokogawa Electric Corporation.
The web server accepts
access by IP address. When a worm that randomly searches for IP addresses
intrudes into the network, it could potentially be attacked by the worm.
The
affected products and versions are as follows: FAST/TOOLS (Packages: RVSVRN, UNSVRN, HMIWEB, FTEES, HMIMOB) R9.01 to
R10.04
CVE-2022-46415DJI 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.
