The vulnerability resides within the \u003ccode\u003efromRouteStatic\u003c/code\u003e function of the \u003ccode\u003e/goform/RouteStatic\u003c/code\u003e file. Successful exploitation of this flaw allows a remote attacker to execute arbitrary code due to a buffer overflow. The vulnerability is triggered by manipulating the \u003ccode\u003epage\u003c/code\u003e argument. Publicly available exploit code exists, increasing the risk of widespread exploitation. This vulnerability poses a significant threat to organizations and individuals using the affected Tenda router model, as it could lead to complete system compromise.\u003c/p\u003e\n\u003ch2 id=\"attack-chain\"\u003eAttack Chain\u003c/h2\u003e\n\u003col\u003e\n\u003cli\u003eAttacker identifies a Tenda F456 router version 1.0.0.5 exposed to the internet.\u003c/li\u003e\n\u003cli\u003eThe attacker crafts a malicious HTTP request targeting the \u003ccode\u003e/goform/RouteStatic\u003c/code\u003e endpoint.\u003c/li\u003e\n\u003cli\u003eThe HTTP request includes the \u003ccode\u003epage\u003c/code\u003e argument with a payload exceeding the expected buffer size within the \u003ccode\u003efromRouteStatic\u003c/code\u003e function.\u003c/li\u003e\n\u003cli\u003eThe \u003ccode\u003efromRouteStatic\u003c/code\u003e function processes the oversized \u003ccode\u003epage\u003c/code\u003e argument without proper bounds checking.\u003c/li\u003e\n\u003cli\u003eThe buffer overflow overwrites adjacent memory regions, potentially including critical program data or execution pointers.\u003c/li\u003e\n\u003cli\u003eThe attacker redirects execution flow to injected malicious code within the overflowed buffer.\u003c/li\u003e\n\u003cli\u003eThe injected code executes with the privileges of the web server process.\u003c/li\u003e\n\u003cli\u003eThe attacker gains complete control of the router, potentially leading to data exfiltration, denial of service, or further network compromise.\u003c/li\u003e\n\u003c/ol\u003e\n\u003ch2 id=\"impact\"\u003eImpact\u003c/h2\u003e\n\u003cp\u003eSuccessful exploitation of CVE-2026-7030 allows a remote attacker to gain complete control of the affected Tenda F456 router.
