| Title | D-Link DAP-1620 1.03 Buffer Overflow |
|---|
| Description | A critical vulnerability has been found in the D-Link DAP-1620 router with firmware version 1.03, affecting the `check_dws_cookie` function. This vulnerability occurs when processing HTTP requests with paths starting with "/storage", leading to a stack-based buffer overflow. The issue is made worse when `check_dws_cookie` calls the `mod_graph_auth_uri_handler` function, which uses an unsafe method to format the request address. If the request address is too long, it can cause a stack overflow. This allows an attacker to overwrite memory, potentially leading to device crashes, denial-of-service (DoS) conditions, or remote code execution, thereby compromising the router's security and the connected network. |
