NetgearCVEs & Vulnerabilities

An issue was discovered on NETGEAR WNR1000V4 1.1.0.54 devices. The web management interface (setup.cgi) has an authentication bypass and other problems that ultimately allow an attacker to remotely compromise the device from a malicious webpage. The attacker sends an FW_remote.htm&todo=cfg_init request without a cookie, reads the Set-Cookie header in the 401 Unauthorized response, and then repeats the FW_remote.htm&todo=cfg_init request with the specified cookie.

An issue was discovered on NETGEAR WNR1000V4 1.1.0.54 devices. Multiple actions within the web management interface (setup.cgi) are vulnerable to command injection, allowing remote attackers to execute arbitrary commands, as demonstrated by shell metacharacters in the sysDNSHost parameter.

An issue was discovered on NETGEAR WNR1000V4 1.1.0.54 devices. Multiple actions within the WNR1000V4 web management console are vulnerable to an unauthenticated GET request (exploitable directly or through CSRF), as demonstrated by the setup.cgi?todo=save_htp_account URI.

An issue was discovered on NETGEAR WNR1000V4 1.1.0.54 devices. Multiple pages (setup.cgi and adv_index.htm) within the web management console are vulnerable to stored XSS, as demonstrated by the configuration of the UI language.

In NETGEAR Nighthawk X10-R900 prior to 1.0.4.24, by sending a DHCP discover request containing a malicious hostname field, an attacker may execute stored XSS attacks against this device. When the malicious DHCP request is received, the device will generate a log entry containing the malicious hostname. This log entry may then be viewed at Advanced settings->Administration->Logs to trigger the exploit. Although this value is inserted into a textarea tag, converted to all-caps, and limited in length, attacks are still possible.

In NETGEAR Nighthawk X10-R900 prior to 1.0.4.24, an attacker may execute stored XSS attacks against this device by supplying a malicious X-Forwarded-For header while performing an incorrect login attempt. The value supplied by this header will be inserted into administrative logs, found at Advanced settings->Administration->Logs, and may trigger when the page is viewed. Although this value is inserted into a textarea tag, the attack simply needs to supply a closing textarea tag.

In NETGEAR Nighthawk X10-R9000 prior to 1.0.4.26, an attacker may execute arbitrary system commands as root by sending a specially-crafted MAC address to the "NETGEAR Genie" SOAP endpoint at AdvancedQoS:GetCurrentBandwidthByMAC. Although this requires QoS being enabled, advanced QoS being enabled, and a valid authentication JWT, additional vulnerabilities (CVE-2019-12510) allow an attacker to interact with the entire SOAP API without authentication. Additionally, DNS rebinding techniques may be used to exploit this vulnerability remotely. Exploiting this vulnerability is somewhat involved. The following limitations apply to the payload and must be overcome for successful exploitation: - No more than 17 characters may be used. - At least one colon must be included to prevent mangling. - A single-quote and meta-character must be used to break out of the existing command. - Parent command remnants after the injection point must be dealt with. - The payload must be in all-caps. Despite these limitations, it is still possible to gain access to an interactive root shell via this vulnerability. Since the web server assigns certain HTTP headers to environment variables with all-caps names, it is possible to insert a payload into one such header and reference the subsequent environment variable in the injection point.

In NETGEAR Nighthawk X10-R900 prior to 1.0.4.26, an attacker may bypass all authentication checks on the device's "NETGEAR Genie" SOAP API ("/soap/server_sa") by supplying a malicious X-Forwarded-For header of the device's LAN IP address (192.168.1.1) in every request. As a result, an attacker may modify almost all of the device's settings and view various configuration settings.

An exploitable denial-of-service vulnerability exists in the Host Access Point Daemon (hostapd) on the NETGEAR N300 (WNR2000v5 with Firmware Version V1.0.0.70) wireless router. A SOAP request sent in an invalid sequence to the <WFAWLANConfig:1#PutMessage> service can cause a null pointer dereference, resulting in the hostapd service crashing. An unauthenticated attacker can send a specially-crafted SOAP request to trigger this vulnerability.

An exploitable denial-of-service vulnerability exists in the session handling functionality of the NETGEAR N300 (WNR2000v5 with Firmware Version V1.0.0.70) HTTP server. An HTTP request with an empty User-Agent string sent to a page requiring authentication can cause a null pointer dereference, resulting in the HTTP service crashing. An unauthenticated attacker can send a specially crafted HTTP request to trigger this vulnerability.

An issue was discovered on NETGEAR Nighthawk M1 (MR1100) devices before 12.06.03. System commands can be executed, via the web interface, after authentication.

An issue was discovered on NETGEAR Nighthawk M1 (MR1100) devices before 12.06.03. The web-interface Cross-Site Request Forgery token is stored in a dynamically generated JavaScript file, and therefore can be embedded in third party pages, and re-used against the Nighthawk web interface. This entirely bypasses the intended security benefits of the use of a CSRF-protection token.

NETGEAR EX7000 V1.0.0.42_1.0.94 devices allow XSS via the SSID.

A stack-based buffer overflow in the upnpd binary running on NETGEAR WNDR3400v3 routers with firmware version 1.0.1.18_1.0.63 allows an attacker to remotely execute arbitrary code via a crafted UPnP SSDP packet.

/api/2.0/rest/aggregator/xml in Axentra firmware, used by NETGEAR Stora, Seagate GoFlex Home, and MEDION LifeCloud, has an XXE vulnerability that can be chained with an SSRF bug to gain remote command execution as root. It can be triggered by anyone who knows the IP address of the affected device.

An exploitable information disclosure vulnerability exists in the KCodes NetUSB.ko kernel module that enables the ReadySHARE Printer functionality of at least two NETGEAR Nighthawk Routers and potentially several other vendors/products. An unauthenticated, remote attacker can craft and send a packet containing an opcode that will trigger the kernel module to return several addresses. One of which can be used to calculate the dynamic base address of the module for further exploitation.

An exploitable arbitrary memory read vulnerability exists in the KCodes NetUSB.ko kernel module which enables the ReadySHARE Printer functionality of at least two NETGEAR Nighthawk Routers and potentially several other vendors/products. A specially crafted index value can cause an invalid memory read, resulting in a denial of service or remote information disclosure. An unauthenticated attacker can send a crafted packet on the local network to trigger this vulnerability.

In NETGEAR ReadyNAS Surveillance before 1.4.3-17 x86 and before 1.1.4-7 ARM, $_GET['uploaddir'] is not escaped and is passed to system() through $tmp_upload_dir, leading to upgrade_handle.php?cmd=writeuploaddir remote command execution.

NETGEAR Insight Cloud with firmware before Insight 5.6 allows remote authenticated users to achieve command injection.

A vulnerability is in the 'BSW_cxttongr.htm' page of the Netgear DGN2200, version DGN2200-V1.0.0.50_7.0.50, and DGND3700, version DGND3700-V1.0.0.17_1.0.17, which can allow a remote attacker to access this page without any authentication. When processed, it exposes the admin password in clear text before it gets redirected to absw_vfysucc.cgia. An attacker can use this password to gain administrator access to the targeted router's web interface.

There are few web pages associated with the genie app on the Netgear WNDR4500 running firmware version V1.0.1.40_1.0.6877. Genie app adds some capabilities over the Web GUI and can be accessed even when you are away from home. A remote attacker can access genie_ping.htm or genie_ping2.htm or genie_ping3.htm page without authentication. Once accessed, the page will be redirected to the aCongratulations2.htma page, which reveals some sensitive information such as 2.4GHz & 5GHz Wireless Network Name (SSID) and Network Key (Password) in clear text.

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.
