Title

NETGEAR WAC104身份验证绕过漏洞

Description

NETGEAR WAC104是美国网件（Netgear）公司的一款无线接入点（AP）。 NETGEAR WAC104身份验证绕过漏洞，未经身份验证的攻击者可以利用该漏洞通过将&currentsetting.htm子字符串添加到HTTP查询来调用任何操作。这直接允许攻击者更改web UI密码，并最终启用调试模式（telnetd）并在设备上获得一个shell作为管理员限制的用户帐户。

CVE-2021-35973 (GCVE-0-2021-35973)

Vulnerability from cvelistv5 – Published: 2021-06-30 14:41 – Updated: 2024-08-04 00:47

Summary

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).

Severity

9.8 (Critical)
