CVE-2026-71292
No affected components available
Subrion CMS's admin grid sorting helper, _gridGetSorting() in includes/classes/ia.base.controller.admin.php, whitelists the dir (ASC/DESC) request parameter via in_array(), but falls back to the raw, attacker-supplied sort GET parameter whenever the requested key is not present in the per-controller $_gridSorting whitelist array: $column = isset($this->_gridSorting[$params['sort']]) ? ... : $params['sort'];, which is then placed into sprintf(' ORDER BY %s%s %s', $tableAlias, $column, $direction) with only backtick-quoting and no escaping. Because a backtick in the payload breaks out of the identifier context, an authenticated admin session can inject arbitrary SQL (error-based via EXTRACTVALUE, or time-based via SLEEP()) to extract database contents including administrator password hashes. Most of Subrion's ~29 admin grid controllers either define no $_gridSorting whitelist at all (e.g. pages.php, transactions.php, languages.php) or an incomplete one covering only some of their sortable columns (e.g. members.php whitelists only 1 of 7 sortable fields), making the vast majority of admin grid endpoints exploitable.
The vulnerability can be exploited over the network without needing physical access. It is easy for an attacker to exploit this vulnerability. An attacker needs high-level or administrative privileges. No user interaction is needed for the attacker to exploit this vulnerability. The impact is confined to the system where the vulnerability exists. There is a high impact on the confidentiality of the information. There is a high impact on the integrity of the data. There is a high impact on the availability of the system.
Exploitation attempts have been detected. Elevated vigilance and prompt remediation are advised.
The exploit probability is very low. The vulnerability is unlikely to be exploited in the next 30 days.
We did not find any exploit available. Neither in GitHub repositories nor in the Exploit-Database.
