4Description
A flaw has been found in Tenda AC5 15.03.06.47. This vulnerability affects the function formQuickIndex of the file /goform/QuickIndex of the component POST Request Handler. This manipulation of the argument PPPOEPassword causes stack-based buffer overflow. The attack may be initiated remotely. The exploit has been published and may be used.
Analysis
Remote attackers with low-level credentials can execute arbitrary code on Tenda AC5 wireless routers running firmware version 15.03.06.47 by exploiting a stack-based buffer overflow in the formQuickIndex function via a crafted PPPOEPassword parameter in POST requests to /goform/QuickIndex. Publicly available exploit code exists, including detailed proof-of-concept documentation published on Notion, elevating immediate risk for devices exposed to authenticated network users. …
