The NSDP protocol implementation on NETGEAR JGS516PE/GS116Ev2 v2.6.0.43 devices was affected by an authentication issue that allows an attacker to bypass access controls and obtain full control of the device.

Multiple integer overflow parameters were found in the web administration panel on NETGEAR JGS516PE/GS116Ev2 v2.6.0.43 devices. Most of the integer parameters sent through the web server can be abused to cause a denial of service attack.

The authentication token required to execute NSDP write requests on NETGEAR JGS516PE/GS116Ev2 v2.6.0.43 devices is not properly invalidated and can be reused until a new token is generated, which allows attackers (with access to network traffic) to effectively gain administrative privileges.

A cross-site scripting (XSS) vulnerability in the administration web panel on NETGEAR JGS516PE/GS116Ev2 v2.6.0.43 devices allows remote attackers to inject arbitrary web script or HTML via the language parameter.

A buffer overflow vulnerability in the access control section on NETGEAR JGS516PE/GS116Ev2 v2.6.0.43 devices (in the administration web panel) allows an attacker to inject IP addresses into the whitelist via the checkedList parameter to the delete command.

NETGEAR JGS516PE/GS116Ev2 v2.6.0.43 devices allow unauthenticated users to modify the switch DHCP configuration by sending the corresponding write request command.

The NSDP protocol implementation on NETGEAR JGS516PE/GS116Ev2 v2.6.0.43 devices was not properly validating the length of string parameters sent in write requests, potentially allowing denial of service attacks.

A buffer overflow vulnerability in the NSDP protocol authentication method on NETGEAR JGS516PE/GS116Ev2 v2.6.0.43 devices allows remote unauthenticated attackers to force a device reboot.

The CSRF protection mechanism implemented in the web administration panel on NETGEAR JGS516PE/GS116Ev2 v2.6.0.43 devices could be bypassed by omitting the CSRF token parameter in HTTP requests.

Rejected reason: DO NOT USE THIS CANDIDATE NUMBER. ConsultIDs: CVE-2020-35783. Reason: This candidate is a reservation duplicate of CVE-2020-35783. Notes: All CVE users should reference CVE-2020-35783 instead of this candidate. All references and descriptions in this candidate have been removed to prevent accidental usage

The hashing algorithm implemented for NSDP password authentication on NETGEAR JGS516PE/GS116Ev2 v2.6.0.43 devices was found to be insecure, allowing attackers (with access to a network capture) to quickly generate multiple collisions to generate valid passwords, or infer some parts of the original.

Rejected reason: DO NOT USE THIS CANDIDATE NUMBER. ConsultIDs: CVE-2020-35801. Reason: This candidate is a reservation duplicate of CVE-2020-35801. Notes: All CVE users should reference CVE-2020-35801 instead of this candidate. All references and descriptions in this candidate have been removed to prevent accidental usage

This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of NETGEAR R6020, R6080, R6120, R6220, R6260, R6700v2, R6800, R6900v2, R7450, JNR3210, WNR2020, Nighthawk AC2100, and Nighthawk AC2400 routers. Although authentication is required to exploit this vulnerability, the existing authentication mechanism can be bypassed. The specific flaw exists within the mini_httpd service, which listens on TCP port 80 by default. When parsing the funjsq_access_token parameter, the process does not properly validate a user-supplied string before using it to execute a system call. An attacker can leverage this vulnerability to execute code in the context of root. Was ZDI-CAN-11653.

This vulnerability allows network-adjacent attackers to bypass authentication on affected installations of NETGEAR R6020, R6080, R6120, R6220, R6260, R6700v2, R6800, R6900v2, R7450, JNR3210, WNR2020, Nighthawk AC2100, and Nighthawk AC2400 routers. Authentication is not required to exploit this vulnerability. The specific flaw exists within the mini_httpd service, which listens on TCP port 80 by default. The issue results from incorrect string matching logic when accessing protected pages. An attacker can leverage this in conjunction with other vulnerabilities to execute code in the context of root. Was ZDI-CAN-11355.
