CVE-2025-2620 is a critical stack-based buffer overflow vulnerability in D-Link DAP-1620 firmware version 1.03. The flaw affects the function mod_graph_auth_uri_handler in the /storage component's authentication handler. Improper handling of attacker-controlled input can cause a stack-based buffer overflow, allowing memory corruption during request processing. The issue is remotely exploitable, public exploit details are available, and the affected product is end-of-life and no longer supported by the vendor.

This repository provides a proof-of-concept exploit for CVE-2025-2620, a critical stack-based buffer overflow in the D-Link DAP-1620 router (firmware 1.03). The exploit is implemented in Python (CVE-2025-2620 poc.py) and targets the router's /storage HTTP endpoint, specifically the 'auth' parameter, which is vulnerable due to improper bounds checking in the mod_graph_auth_uri_handler function. The exploit can operate in two modes: 'overflow' (to find the offset for EIP/RA overwrite using a cyclic pattern) and 'rce' (to deliver a buffer overflow payload with custom MIPS shellcode for remote code execution, resulting in a reverse shell to the attacker's machine). The README.md provides detailed technical background, usage instructions, and guidance for adapting the exploit to different environments. The exploit requires no authentication and can be triggered remotely over the network, making it highly critical. The repository is well-structured, with clear separation between documentation and exploit code, and is intended for security research and demonstration purposes.
