Actively exploited vulnerabilities affecting DD-WRT products.https://wildfortech.comhttps://wildfortech.com/security#CVE-2021-27137https://wildfortech.com/security#CVE-2021-27137This vulnerability in DD-WRT router firmware allows an unauthenticated attacker — someone with no login credentials — to overflow a buffer in the UPnP service and potentially execute arbitrary code on the device. Because it requires no authentication and targets a widely deployed open-source router platform, a successful exploit could give an attacker full control over affected routers, enabling traffic interception, network pivoting, or further attacks on connected systems.Tue, 21 Jul 2026 00:00:00 GMTDD-WRTDD-WRT
