CVE-2026-54348
Froxlor: Second-Order SQL Injection via `Admins.add` `ipaddress` Parameter Allows Full Database Exfiltration
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.
