Authenticated code execution via REMOTE_ADDR stack overflow
Published Jun 15, 2020 · Updated Aug 4, 2024
Stack-based buffer overflow in TRENDnet TEW-827DRU through 2.06B04 allows remote authenticated users to execute arbitrary code. The ssi binary processes an oversized REMOTE_ADDR value sent to apply.cgi's wifi_captive_portal_login action without enforcing the stack buffer's capacity. Authenticated access to the web-management interface is required, and successful exploitation executes code on the router.
