Froxlor是Froxlor组织开源的一款服务器管理软件。 Froxlor 2.3.8之前版本存在SQL注入漏洞，该漏洞源于对ipaddress数组处理不当，未强制数字元素类型且未使用参数化查询，可能导致具有change_serversettings权限的已认证管理员通过UNION-based有效载荷检索任意数据库数据（包括管理员登录名和bcrypt密码哈希），甚至造成权限提升。

Vulnerability Title
Froxlor: Second-Order SQL Injection via `Admins.add` `ipaddress` Parameter Allows Full Database Exfiltration
Source: CVE Program / CVE List V5
Vulnerability Description
Froxlor is open source server administration software. Prior to 2.3.8, the Admins.add and Admins.update endpoints in lib/Froxlor/Api/Commands/Admins.php accept an attacker-controlled ipaddress array and store it as JSON in panel_admins.ip without enforcing numeric element types. When the poisoned account later calls IpsAndPorts.listing, lib/Froxlor/Api/Commands/IpsAndPorts.php decodes the array and concatenates its elements into a SQL IN clause without casting or parameterization; the same unsafe pattern is present in lib/Froxlor/Api/Commands/Domains.php. An authenticated administrator with change_serversettings permission can store a UNION-based payload and trigger it through the poisoned account to retrieve arbitrary database data, including administrator login names and bcrypt password hashes, with potential privilege escalation and broader database impact. This issue is fixed in version 2.3.8.
