云安全中心应急漏洞扫描

云安全中心是一个实时识别、分析、预警安全威胁的统一安全管理系统，通过防勒索、防病毒、防篡改、合规检查等安全能力，实现威胁检测、告警响应、攻击溯源的自动化安全运营闭环，保护云上资产和本地服务器安全，并满足监管合规要求。

前提条件配置

①子账户生成阿里云的AKSK信息，授权云安全中心权限

②python环境配置

 1安装依赖
 2yum -y install zlib-devel bzip2-devel openssl-devel ncurses-devel gdbm-devel sqlite-devel readline-devel tk-devel gcc make libffi-devel gcc-c++ libffi  zlib zlib-dev libssl-dev db4-devel libpcap-devel xz-devel
 3
 4
 5下载python3.10.4
 6wget -c  https://www.python.org/ftp/python/3.10.4/Python-3.10.4.tgz
 7
 8解压python3.10.4
 9tar -zxvf Python-3.10.4.tgz
10
11cd Python-3.10.4/
12./configure  --with-ssl
13make && make install
14
15备份python文件
16mv /usr/bin/python /usr/bin/python.bak
17
18#建立python3的软链接
19ln -s /usr/local/bin/python3 /usr/bin/python
20
21which pip3
22#yum执行异常解决
23vi /usr/libexec/urlgrabber-ext-down
24#! /usr/bin/python2
25
26vi /usr/bin/yum
27#!/usr/bin/python2
28
29
30安装模块
31pip3 install --upgrade pip
32pip3 install  alibabacloud_sas20181203==1.1.13
33pip install alibabacloud_tea_console
34
35如果在import ssl调式报错ImportError: cannot import name 'OPENSSL_VERSION_NUMBER' from '_ssl' (unknown location)解决办法如下
36
37#下载安装openssl
38wget -c   https://www.openssl.org/source/openssl-1.1.1n.tar.gz
39tar -zxvf openssl-1.1.1n.tar.gz
40cd openssl-1.1.1n
41./config --prefix=/usr/local/openssl   
42make && make instal
43mv /usr/bin/openssl /usr/bin/openssl.bak
44ln -sf /usr/local/openssl/bin/openssl /usr/bin/openssl
45echo "/usr/local/openssl/lib" >> /etc/ld.so.conf
46
47ldconfig -v
48
49#查询openssl版本
50openssl version
51
52vim /root/Python-3.10.4/Modules/Setup
53211  OPENSSL=/usr/local/openssl
54212  _ssl _ssl.c \
55213      -I$(OPENSSL)/include -L$(OPENSSL)/lib \
56214      -lssl -lcrypto
57
58
59最后在执行下python3.10.4安装
60cd Python-3.10.4/
61./configure  
62make && make install

一、扫描获取特定应急漏洞的名称信息

如扫描fastjson <= 1.2.80 反序列化任意代码执行漏洞

API文档 https://help.aliyun.com/document_detail/421691.html

Lang:zh

RiskStatus:y

ScanType:python

CheckType:fastjson <= 1.2.80 反序列化任意代码执行漏洞

VulName:

 1{
 2  "TotalCount": 1,
 3  "RequestId": "A79C0E69-CE10-5688-8D01-7322BD3715C8",
 4  "PageSize": 5,
 5  "CurrentPage": 1,
 6  "GroupedVulItems": [
 7    {
 8      "Status": 30,
 9      "PendingCount": 116,
10      "Type": "python",
11      "Description": "fastjson已使用黑白名单用于防御反序列化漏洞，经研究该利用在特定条件下可绕过默认autoType关闭限制，攻击远程服务器，风险影响较大。建议fastjson用户尽快采取安全措施保障系统安全。\n\n特定依赖存在下影响 ≤1.2.80。",
12      "CheckType": 1,
13      "AliasName": "fastjson <= 1.2.80 反序列化任意代码执行漏洞【原理扫描】",
14      "GmtLastCheck": 1653471386000,
15      "GmtPublish": 1653273837000,
16      "Name": "emg:SCA:AVD-2022-1243027"
17    }
18  ]
19}

得到特定应急漏洞名称信息为emg:SCA:AVD-2022-1243027

可以把zip文件解压后上传到oss存储中，通过脚本钉钉推送到指定群通知或者邮件推送指定的人

来个开胃小菜

阿里云CDN刷新目录脚本(刷新之前更换AKSK秘钥,替换object_path刷新的网站URL地址)

pip install alibabacloud_cdn20180510==1.0.11
