Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Froxlor 0.10.0 至 2.3.14 版本（即 2.3.15 之前的所有版本）在 SubDomains.delete API 命令中存在授权缺失漏洞。该漏洞允许已认证的客户通过提供主域名 ID，删除由经销商（reseller）配置的主域名。攻击者可借此绕过 Web 界面限制，删除相关域名，导致虚拟主机（vhost）、DNS 记录及子域名记录成为孤立记录，并将 subdomains_used 计数降至负数，从而非法获取额外的子域名配额。
