VAR-202511-1198

Vulnerability from variot - Updated: 2025-12-19 22:54

A buffer overflow vulnerability exists in the TOTOLINK A950RG Router firmware V5.9c.4592_B20191022_ALL within the global.so binary. The getSaveConfig function retrieves the http_host parameter from user input via websGetVar and copies it into a fixed-size stack buffer (v13) using strcpy() without performing any length checks. An unauthenticated remote attacker can exploit this vulnerability by sending a specially crafted HTTP request to the router's web interface, potentially leading to arbitrary code execution. The TOTOLINK A950RG is a next-generation Gigabit wireless router launched by TOTOLINK, a Chinese electronics company, supporting high-speed network connectivity and multi-device management. This vulnerability stems from a failure to properly validate the length of input data in the global.so binary file. Detailed vulnerability information is currently unavailable

CVE-2025-60699 (GCVE-0-2025-60699)

Vulnerability from cvelistv5 – Published: 2025-11-13 00:00 – Updated: 2025-11-14 16:50

Summary

A buffer overflow vulnerability exists in the TOTOLINK A950RG Router firmware V5.9c.4592_B20191022_ALL within the `global.so` binary. The `getSaveConfig` function retrieves the `http_host` parameter from user input via `websGetVar` and copies it into a fixed-size stack buffer (`v13`) using `strcpy()` without performing any length checks. An unauthenticated remote attacker can exploit this vulnerability by sending a specially crafted HTTP request to the router's web interface, potentially leading to arbitrary code execution.
