A significant security vulnerability has been identified in specific Asus router models, including the DSL-AC51, DSL-AC750, and DSL-N16. This flaw poses a high risk, potentially allowing unauthorized external access and control over these devices. While it is currently unknown if this vulnerability is actively being exploited, the potential for misuse is substantial.

Compromised routers can be repurposed for malicious activities, such as forming botnets or serving as entry points into home networks.
