| Title | Mikrotīkls Router Firmware <=6.40.9/6.42rc27 Buffer Overflow |
|---|
| Description | RouterOS is a network operating system based on the Linux kernel. In MikroTik RouterOS version 6.40.5, sending a UDP packet to port 137 can trigger a buffer overflow in the smb service. The overflow occurs before authentication, allowing unauthenticated remote attackers to potentially exploit it to cause a denial of service. All architectures and devices running RouterOS versions prior to 6.40.5/6.42rc27 are vulnerable.Malicious code cannot be injected. |
