CVE-2026-7036 Details
Description
A vulnerability was identified in Tenda i9 1.0.0.5(2204). This vulnerability affects the function R7WebsSecurityHandlerfunction of the component HTTP Handler. The manipulation leads to path traversal. Remote exploitation of the attack is possible. The exploit is publicly available and might be used.
A critical path traversal vulnerability has been identified in the Tenda i9 router, specifically in the 1.0.0.5(2204) firmware version. The issue arises within the R7WebsSecurityHandlerfunction, which is responsible for managing incoming HTTP requests. This function implements a URL prefix whitelist to allow unauthenticated access to certain static resources. However, it fails to properly validate or canonicalize the URL paths, enabling remote attackers to exploit this oversight. By crafting requests that include directory traversal sequences, attackers can bypass authentication and access sensitive files or administrative interfaces.
