Certain D-Link, Edimax, NETGEAR, TP-Link, Tenda, and Western Digital devices are affected by an integer overflow by an unauthenticated attacker. Remote code execution from the WAN interface (TCP port 20005) cannot be ruled out; however, exploitability was judged to be of "rather significant complexity" but not "impossible." The overflow is in SoftwareBus_dispatchNormalEPMsgOut in the KCodes NetUSB kernel module. Affected NETGEAR devices are D7800 before 1.0.1.68, R6400v2 before 1.0.4.122, and R6700v3 before 1.0.4.122.

Certain NETGEAR devices are affected by command injection by an unauthenticated attacker. This affects RBK40 before 2.5.1.16, RBR40 before 2.5.1.16, RBS40 before 2.5.1.16, RBK20 before 2.5.1.16, RBR20 before 2.5.1.16, RBS20 before 2.5.1.16, RBK50 before 2.5.1.16, RBR50 before 2.5.1.16, RBS50 before 2.5.1.16, and RBS50Y before 2.6.1.40.

ping.cgi on NETGEAR DGN2200 devices with firmware through 10.0.0.50 allows remote authenticated users to execute arbitrary OS commands via shell metacharacters in the ping_IPAddr field of an HTTP POST request.

NETGEAR WAC104 devices before 1.0.4.15 are affected by an authentication bypass vulnerability in /usr/sbin/mini_httpd, allowing an unauthenticated attacker to invoke any action by adding the &currentsetting.htm substring to the HTTP query, a related issue to CVE-2020-27866. This directly allows the attacker to change the web UI password, and eventually to enable debug mode (telnetd) and gain a shell on the device as the admin limited-user account (however, escalation to root is simple because of weak permissions on the /etc/ directory).

Certain NETGEAR devices are affected by command execution. This affects M4200-10MG-POE+ 12.0.2.11 and earlier, M4300-28G 12.0.2.11 and earlier, M4300-52G 12.0.2.11 and earlier, M4300-28G-POE+ 12.0.2.11 and earlier, M4300-52G-POE+ 12.0.2.11 and earlier, M4300-8X8F 12.0.2.11 and earlier, M4300-12X12F 12.0.2.11 and earlier, M4300-24X24F 12.0.2.11 and earlier, M4300-24X 12.0.2.11 and earlier, and M4300-48X 12.0.2.11 and earlier.

Buffer Overflow in Netgear R8000 Router with firmware v1.0.4.56 allows remote attackers to execute arbitrary code or cause a denial-of-service by sending a crafted POST to '/bd_genie_create_account.cgi' with a sufficiently long parameter 'register_country'.

Certain NETGEAR devices are affected by command injection by an unauthenticated attacker via the vulnerable /sqfs/lib/libsal.so.0.0 library used by a CGI application, as demonstrated by setup.cgi?token=';$HTTP_USER_AGENT;' with an OS command in the User-Agent field.

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 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 wan_hostname and forcing a reboot. This will result in command injection.

Authentication is not required to exploit this vulnerability. The specific flaw exists within the processing of SOAP requests. The issue results from the lack of proper authentication verification before performing a password reset. An attacker can leverage this vulnerability to reset the admin password. Was ZDI-CAN-13483.

An issue was discovered on NETGEAR Orbi Tri-Band Business WiFi Add-on Satellite (SRS60) AC3000 V2.5.1.106, Outdoor Satellite (RBS50Y) V2.5.1.106, and Pro Tri-Band Business WiFi Router (SRR60) AC3000 V2.5.1.106.
