Glances Central Browser Autodiscovery Leaks Reusable Credentials to Zeroconf-Spoofed Servers

Glances is an open-source system cross-platform monitoring tool. Prior to version 4.5.2, in Central Browser mode, Glances stores both the Zeroconf-advertised server name and the discovered IP address for dynamic servers, but later builds connection URIs from the untrusted advertised name instead of the discovered IP. When a dynamic server reports itself as protected, Glances also uses that same untrusted name as the lookup key for saved passwords and the global `[passwords] default` credential. An attacker on the same local network can advertise a fake Glances service over Zeroconf and cause the browser to automatically send a reusable Glances authentication secret to an attacker-controlled host. This affects the background polling path and the REST/WebUI click-through path in Central Browser mode. Version 4.5.2 fixes the issue.

glances 安全漏洞

glances是Nicolas Hennion个人开发者的一款系统监测工具。 Glances 4.5.2之前版本存在安全漏洞，该漏洞源于Central Browser模式下使用不受信任的广告名称构建连接URI和查找密钥，可能导致本地网络攻击者诱使浏览器向攻击者控制的主机发送可重用身份验证密钥。
