A path traversal vulnerability has been identified in the Tenda i3 router, specifically in the firmware version 1.0.0.6(2204). The issue arises in the R7WebsSecurityHandler function, which is responsible for filtering HTTP requests. The vulnerability allows remote attackers to bypass authentication and access sensitive files by exploiting the application's failure to properly validate or canonicalize URL paths. By sending a crafted HTTP request that includes directory traversal sequences, attackers can escape restricted directories and gain unauthorized access to administrative functions.
