What is CVE-2025-9245?

A stack-based buffer overflow vulnerability exists in the WPSSTAPINEnr function of several Linksys wireless routers, including models RE6250, RE6300, RE6350, RE6500, RE7000, and RE9000. When an attacker manipulates the 'ssid' argument in requests to the router's /goform/WPSSTAPINEnr endpoint, it can lead to remote code execution due to memory corruption. The risk escalates as the exploit has been made publicly available, presenting a potential immediate threat to users. Despite prior notification, the vendor has not issued a response or patch.

Affected Version(s)

RE6250 1.0.013.001
