TP-Link has acknowledged a zero-day vulnerability affecting multiple router models, which allows for remote code execution due to a stack-based buffer overflow in its CWMP implementation. While a patch is available for European models, users are advised to change default passwords and disable CWMP if not needed until more fixes are released. Additionally, CISA has warned about previously exploited vulnerabilities in TP-Link routers that have been used by threat actors for malicious activities.
