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. Se encontró que el algoritmo hash implementado para la autenticación de contraseña NSDP en dispositivos NETGEAR JGS516PE/GS116Ev2 versión v2.6.0.43, era no seguro, lo cual permite a atacantes (con acceso a una captura de red) generar rápidamente múltiples colisiones para generar contraseñas válidas o inferir algunas partes del original • https://research.nccgroup.com/2021/03/08/technical-advisory-multiple-vulnerabilities-in-netgear-prosafe-plus-jgs516pe-gs116ev2-switches • CWE-326: Inadequate Encryption Strength •
CVSS: 8.8EPSS: 1%CPEs: 86EXPL: 0CVE-2021-27255 – NETGEAR R7800 funjsq_httpd Missing Authentication for Critical Function Remote Code Execution Vulnerability
https://notcve.org/view.php?id=CVE-2021-27255
This vulnerability allows remote attackers to execute arbitrary code on affected installations of NETGEAR R7800 firmware version 1.0.2.76. Authentication is not required to exploit this vulnerability. The specific flaw exists within the refresh_status.aspx endpoint. The issue results from a lack of authentication required to start a service on the server. An attacker can leverage this vulnerability to execute code in the context of root. • https://kb.netgear.com/000062883/Security-Advisory-for-Multiple-Vulnerabilities-on-Some-Routers-Satellites-and-Extenders https://www.zerodayinitiative.com/advisories/ZDI-21-263 • CWE-306: Missing Authentication for Critical Function •

https://notcve.org/view.php?id=CVE-2021-27257
This vulnerability allows network-adjacent attackers to compromise the integrity of downloaded information on affected installations of NETGEAR R7800 firmware version 1.0.2.76. Authentication is not required to exploit this vulnerability. The specific flaw exists within the downloading of files via FTP. The issue results from the lack of proper validation of the certificate presented by the server. An attacker can leverage this in conjunction with other vulnerabilities to execute arbitrary code in the context of root. • https://kb.netgear.com/000062883/Security-Advisory-for-Multiple-Vulnerabilities-on-Some-Routers-Satellites-and-Extenders https://www.zerodayinitiative.com/advisories/ZDI-21-264 • CWE-295: Improper Certificate Validation •
