NETGEAR WNR854T

Netgear WNR854T 1.5.2 (North America) is vulnerable to Command Injection. An attacker can send a specially crafted request to post.cgi, updating the nvram parameter get_email. After which, they can visit the send_log.cgi endpoint which uses the parameter in a system call to achieve command execution.

In Netgear WNR854T 1.5.2 (North America), the UPNP service is vulnerable to command injection in the function addmap_exec which parses the NewInternalClient parameter of the AddPortMapping SOAPAction into a system call without sanitation. An attacker can send a specially crafted SOAPAction request for AddPortMapping via the router's WANIPConn1 service to achieve arbitrary command execution.

Netgear WNR854T 1.5.2 (North America) is vulnerable to Command Injection. An attacker can send a specially crafted request to post.cgi, updating the nvram parameter pppoe_peer_mac and forcing a reboot. This will result in command injection.

Netgear WNR854T 1.5.2 (North America) is vulnerable to Command Injection. An attacker can send a specially crafted request to post.cgi, updating the nvram parameter wan_hostname and forcing a reboot. This will result in command injection.

Netgear WNR854T 1.5.2 (North America) is vulnerable to Arbitrary command execution in cmd.cgi which allows for the execution of system commands via the web interface.

Netgear WNR854T 1.5.2 (North America) contains a stack-based buffer overflow vulnerability in the SetDefaultConnectionService function due to an unconstrained use of sscanf. The vulnerability allows for control of the program counter and can be utilized to achieve arbitrary code execution.

In Netgear WNR854T 1.5.2 (North America), the UPNP service (/usr/sbin/upnp) is vulnerable to stack-based buffer overflow in the M-SEARCH Host header.

Netgear Inc WNR854T 1.5.2 (North America) contains a stack-based buffer overflow vulnerability in the parse_st_header function due to use of a request header parameter in a strncpy where size is determined based on the input specified. By sending a specially crafted packet, an attacker can take control of the program counter and hijack control flow of the program to execute arbitrary system commands.

NETGEAR WNR854T devices before 1.5.2 are affected by command execution.
