Linux随记（十）

一、升级harbor v2.6.4 --> harbor-offline-installer-v2.11.0-rc3 --> v2.9.4 – 随记

漏洞信息：

CVE-2023-20902timing condition in Harbor 2.6.x and below, Harbor 2.7.2 and below,  Harbor 2.8.2 and below, and Harbor 1.10.17 and below allows an attacker with network access to create jobs/stop job tasks and retrieve job task information.
---
CVE-2022-46463an access control issue in Harbor v1.X.X to v2.5.3 allows attackers to access public and private image repositories without authentication. NOTE: the vendor's position is that this "is clearly described in the documentation as a feature."

环境信息：

harbor1 /nfs_server   1.101 、 harbor2 1.102 、 keepalived 1.200

随记内容：

#1
原版本 v2.6
升级到v2.11 (这玩意有问题，只能登录主ip ，副IP登不上，而且push一直 retry)
然后放弃v2.11 ，去弄v2.9. （这时候主/副都能登录了。）
虽说主副都是挂载nfs的 /data/harbor。 但是他双方的内容是不一致的，#2 这时候去注释yml默认的pg，使用其external database。
搭建了个主从pgsql。不懂为啥harbor-core这时候报错了（说什么脏数据）
后面用了个非主流方法
（主IP还是使用内部的pgsql ， 副IP使用外接pgsql，配置连接到主IP的 pgsql认他为主库）

主–部署pgsql的docker-compose.yml内容：

version: '2'services:postgresql-master:image: bitnami/postgresql:11.14.0ports:- '5432:5432'volumes:- 'postgresql_master_data:/bitnami/postgresql'environment:- 'POSTGRESQL_USERNAME=harbor_db'- 'POSTGRESQL_PASSWORD=123'- 'POSTGRESQL_POSTGRES_PASSWORD=123'- 'POSTGRESQL_REPLICATION_MODE=master'- 'POSTGRESQL_REPLICATION_USER=repl_user'- 'POSTGRESQL_REPLICATION_PASSWORD=repl_password'- 'POSTGRESQL_SYNCHRONOUS_COMMIT_MODE=on'- 'POSTGRESQL_NUM_SYNCHRONOUS_REPLICAS=1'volumes:postgresql_master_data:driver: local

从-部署pgsql的docker-compose.yml内容：

version: '2'services:postgresql-slave:image: bitnami/postgresql:11.14.0ports:- '5432:5432'volumes:- 'postgresql_slave_data:/bitnami/postgresql'environment:- 'POSTGRESQL_USERNAME=harbor_db'- 'POSTGRESQL_PASSWORD=123'- 'POSTGRESQL_POSTGRES_PASSWORD=123'- 'POSTGRESQL_REPLICATION_MODE=slave'- 'POSTGRESQL_REPLICATION_USER=repl_user'- 'POSTGRESQL_REPLICATION_PASSWORD=repl_password'- 'POSTGRESQL_MASTER_HOST=10.xx.xx.xx'   #这里写master pg库的IP- 'POSTGRESQL_MASTER_PORT_NUMBER=5432'volumes:postgresql_slave_data:driver: local

二、iptables处理nfs漏洞（目标主机showmount -e信息泄露(CVE-1999-0554)），并加固其他服务访问 – 随记。

环境信息

K8s 、docker 、nfs 、mysql、iptables
注意下面10.xx.xx.0/24 换成实际的环境IP段。
iptables -nL 看下结果参考：
https://blog.csdn.net/sxf1061700625/article/details/126844812
https://blog.csdn.net/weixin_46516542/article/details/124279644
https://blog.csdn.net/baidu_35848778/article/details/132883593

执行的iptables语句
限制80 / 3306端口（ /符号后面的端口，在-dports后换成对应的端口号即可）

iptables -I INPUT -p tcp -m multiport --dports 80 -j DROP
iptables -I INPUT -s 127.0.0.1 -p tcp -m multiport --dports 80 -j ACCEPT
iptables -I INPUT -s 10.xx.xx.0/24 -p tcp -m multiport --dports 80 -j ACCEPT
iptables -I INPUT -s 10.244.0.0/16 -p tcp -m multiport --dports 80 -j ACCEPT
iptables -I INPUT -s 10.96.0.0/12 -p tcp -m multiport --dports 80 -j ACCEPTiptables -I DOCKER-USER -p tcp -m multiport --dports 80 -j DROP
iptables -I DOCKER-USER -s 127.0.0.1 -p tcp -m multiport --dports 80 -j ACCEPT
iptables -I DOCKER-USER -s 10.xx.xx.0/24 -p tcp -m multiport --dports 80 -j ACCEPT
iptables -I DOCKER-USER -s 10.244.0.0/16 -p tcp -m multiport --dports 80 -j ACCEPT
iptables -I DOCKER-USER -s 10.96.0.0/12 -p tcp -m multiport --dports 80 -j ACCEPTiptables -I DOCKER -p tcp -m multiport --dports 80 -j DROP
iptables -I DOCKER -s 127.0.0.1 -p tcp -m multiport --dports 80 -j ACCEPT
iptables -I DOCKER -s 10.xx.xx.0/24 -p tcp -m multiport --dports 80 -j ACCEPT
iptables -I DOCKER -s 10.244.0.0/16 -p tcp -m multiport --dports 80 -j ACCEPT
iptables -I DOCKER -s 10.96.0.0/12 -p tcp -m multiport --dports 80 -j ACCEPT

限制22端口

iptables -A INPUT -p tcp --dport 22 -s 172.xx.xx.0/24 -j ACCEPT
iptables -A INPUT -p tcp --dport 22 -s 10.xx.xx.129/29 -j ACCEPT

限制其他端口

#### 集群内
iptables -I INPUT -p tcp -m multiport --dports 10250,2379,2380,6443 -j DROP
iptables -I INPUT -s 127.0.0.1 -p tcp -m multiport --dports 10250,2379,2380,6443 -j ACCEPT
iptables -I INPUT -s 10.xx.xx.0/24 -p tcp -m multiport --dports 10250,2379,2380,6443 -j ACCEPT
iptables -I INPUT -s 10.244.0.0/16 -p tcp -m multiport --dports 10250,2379,2380,6443 -j ACCEPT
iptables -I INPUT -s 10.96.0.0/12 -p tcp -m multiport --dports 10250,2379,2380,6443 -j ACCEPT

查看k8s / docker的相关ip段信息（calico、 svc 、docker 等信息）

ip addr show  docker ip范围  
docker network inspect bridge"Subnet": "172.17.0.0/16",k8s的ip范围：
kubectl cluster-info dump | grep -i bind-address -A 6--cluster-cidr=10.244.0.0/16,2001:db8:42:0::/48   kubectl get cm -n kube-system  kubeadm-config   -oyamlpodSubnet: 10.244.0.0/16,2001:db8:42:0::/48serviceSubnet: 10.96.0.0/12,2001:db8:42:1::/108

三、bclinux 8.6的OpenSSL 1.1.1k升级到OpenSSL 3.1.6 （2024年6月版本）（在线和离线rpm包安装方式）

背景描述：

由于OpenSSL 安全漏洞(CVE-2024-2511)）, 而且openssl已经停止维护v1.1.1的。所以选择升级到v3.1.xx版本。
（生产环境是没外网没ISO镜像源的，只能在虚拟机先联网操作后，再去生产上操作。）

3.1 升级过程：

#0 当前openssl 版本

ldconfig -v
]$  openssl version
OpenSSL 3.1.6 4 Jun 2024 (Library: OpenSSL 3.1.6 4 Jun 2024)

3.2 排障过程：（内容没排版，可略）

简单来说就是缺什么依赖/包，就去安装即可。
##### 报错1  you may need to install the IPC::Cmd module所以
[root@localhost openssl-3.1.6]# yum install perl-IPC-Cmd

resetting to kubeadm defaults before a successful upgrade can be performed. The version to manually
upgrade to is denoted in the "PREFERRED VERSION" column.API GROUP                 CURRENT VERSION   PREFERRED VERSION   MANUAL UPGRADE REQUIRED

If you wish to reset iptables, you must do so manually by using the "iptables" command.If your cluster was setup to utilize IPVS, run ipvsadm --clear (or similar)
to reset your system s IPVS tables.The reset process does not clean your kubeconfig files and you must remove them manually.
Please, check the contents of the $HOME/.kube/config file.###再次加入
