NETGEAR DGN setup.cgi OS Command Injection
NETGEAR · DGN1000
The NETGEAR DGN1000 firmware (versions before 1.1.00.48) contains an OS command injection flaw in its setup.cgi endpoint, which fails to neutralize special elements in user-supplied input and lacks authentication for this critical functionality. An unauthenticated remote attacker with network access to the device can send crafted HTTP requests to setup.cgi, with no user interaction or prior configuration required, to execute arbitrary operating system commands as root.
NETGEAR DGN1000 before 1.1.00.48 is vulnerable to an authentication bypass vulnerability.
