Netgear R8500 v1.0.2.160 was discovered to contain multiple stack overflow vulnerabilities in the component wireless.cgi via the opmode, opmode_an, and opmode_an_2 parameters. These vulnerabilities allow attackers to cause a Denial of Service (DoS) via a crafted POST request.

Netgear R8500 v1.0.2.160 was discovered to contain a command injection vulnerability in the sysNewPasswd parameter at password.cgi. This vulnerability allows attackers to execute arbitrary OS commands via a crafted request.

Netgear R8500 v1.0.2.160 was discovered to contain multiple stack overflow vulnerabilities in the component openvpn.cgi via the openvpn_service_port and openvpn_service_port_tun parameters. These vulnerabilities allow attackers to cause a Denial of Service (DoS) via a crafted POST request.

Netgear R8500 v1.0.2.160 was discovered to contain a stack overflow via the share_name parameter at usb_remote_smb_conf.cgi. This vulnerability allows attackers to cause a Denial of Service (DoS) via a crafted POST request.

Netgear R8500 v1.0.2.160 was discovered to contain multiple stack overflow vulnerabilities in the component ipv6_fix.cgi via the ipv6_wan_ipaddr, ipv6_lan_ipaddr, ipv6_wan_length, and ipv6_lan_length parameters. These vulnerabilities allow attackers to cause a Denial of Service (DoS) via a crafted POST request.

Netgear R8500 v1.0.2.160 was discovered to contain a command injection vulnerability in the sysNewPasswd parameter at admin_account.cgi. This vulnerability allows attackers to execute arbitrary OS commands via a crafted request.

Buffer Overflow vulnerability in Netgear- R61 router V1.0.1.28 allows a remote attacker to execute arbitrary code via the QUERY_STRING key value

ProSAFE Plus Configuration Utility prior to 2.3.29 allows remote attackers to bypass access restriction and change configurations of the switch via SOAP requests.

Netgear WNAP320, WNDAP350, and WNDAP360 before 3.5.5.0 reveal wireless passwords and administrative usernames and passwords over SNMP.

Information disclosure in Netgear WN604 before 3.3.3; WNAP210, WNAP320, WNDAP350, and WNDAP360 before 3.5.5.0; and WND930 before 2.0.11 allows remote attackers to read the wireless WPS PIN or passphrase by visiting unauthenticated webpages.

Cross-site request forgery (CSRF) vulnerability in NETGEAR DGN2200 routers with firmware 10.0.0.20 through 10.0.0.50 allows remote attackers to hijack the authentication of users for requests that perform DNS lookups via the host_name parameter to dnslookup.cgi. NOTE: this issue can be combined with CVE-2017-6334 to execute arbitrary code remotely.

The NETGEAR WNR2000v5 router allows an administrator to perform sensitive actions by invoking the apply.cgi URL on the web server of the device. This special URL is handled by the embedded web server (uhttpd) and processed accordingly. The web server also contains another URL, apply_noauth.cgi, that allows an unauthenticated user to perform sensitive actions on the device. This functionality can be exploited to change the router settings (such as the answers to the password-recovery questions) and achieve remote code execution.

The NETGEAR WNR2000v5 router leaks its serial number when performing a request to the /BRS_netgear_success.html URI. This serial number allows a user to obtain the administrator username and password, when used in combination with the CVE-2016-10176 vulnerability that allows resetting the answers to the password-recovery questions.

The default console presented to users over telnet (when enabled) is restricted to a subset of commands. Commands issued at this console, however, appear to be fed directly into a system call or other similar function. This allows any authenticated user to execute arbitrary commands on the device.

A support user exists on the device and appears to be a backdoor for Technical Support staff. The default password for this account is “support” and cannot be changed by a user via any normally accessible means.

The “puhttpsniff” service, which runs by default, is susceptible to command injection due to improperly sanitized user input. An unauthenticated attacker on the same network segment as the router can execute arbitrary commands on the device without authentication.

An exploitable firmware modification vulnerability was discovered on the Netgear WNR2000v1 router. An attacker can conduct a MITM (Man-in-the-Middle) attack to modify the user-uploaded firmware image and bypass the CRC check, allowing attackers to execute arbitrary code or cause a Denial of Service (DoS). This affects v1.2.3.7 and earlier.

An issue in Netgear WNR2000 v1 1.2.3.7 and earlier allows authenticated attackers to cause a Denial of Service (DoS) via uploading a crafted firmware image during the firmware update process.

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 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.
