Re: Artiphp CMS 5.5.0 Database Backup Disclosure Exploit
这个漏洞挺典型的，Artiphp CMS 5.5.0 把数据库备份文件放在了 web 根目录下，而且文件名只按日期变化，攻击者靠遍历日期就能直接下载备份。备份里肯定包含管理员账号密码、用户数据等敏感信息，风险很高。 如果有人在用这个版本，建议尽快升级到不受影响的新版，或者修改 backupDB() 函数的备份路径和文件名规则，不要把备份放到可公开访问的目录里，最好再加上随机字符串或者访问权限验证。另外也可以考虑在服务器层面禁止直接访问 /artzone/artpublic/database/ 路径下的 .sql.gz 文件。Re: Artiphp CMS 5.5.0 Database Backup Disclosure Exploit
谢谢分享，这个漏洞确实挺危险的。备份文件放在 web 根目录下，文件名还按日期规律生成，攻击者直接遍历就能下载数据库，等于把整个站点的数据拱手让人。建议使用这个 CMS 的用户尽快检查一下 `/artzone/artpublic/database/` 目录下是否有历史备份，同时升级到最新版本或者把备份目录移到 web 访问不到的路径下，并配合 `.htaccess` 限制访问。楼主有尝试复现成功吗？Re: Artiphp CMS 5.5.0 Database Backup Disclosure Exploit
这是一个比较经典的CMS数据库备份泄露漏洞。Artiphp CMS 5.5.0版本在使用`backupDB()`备份数据库时，将备份文件直接存放在web根目录下，且文件名遵循固定的日期格式`db_backup_..sql.gz`，攻击者可以通过遍历日期组合轻易下载到数据库文件，导致敏感信息泄露。 这个漏洞的危害性在于不需要认证即可下载完整数据库，包括用户密码、配置信息等敏感数据。建议使用该CMS的站长尽快检查`/artzone/artpublic/database/`目录下是否存在此类备份文件，并考虑删除或将其移至web访问目录之外。同时也可以关注官方是否有新版本修复该问题。
