Detailsinfo

A vulnerability was found in Intelliant Subrion up to 4.2.1. It has been classified as problematic. Affected is the function _gridGetSorting of the file includes/classes/ia.base.controller.admin.php of the component Sorting Helper. The manipulation of the argument sort with an unknown input leads to a sql injection vulnerability. CWE is classifying the issue as CWE-89. The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

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 advisory is available at github.com. This vulnerability is traded as CVE-2026-71292 since 08/05/2026. The exploitability is told to be easy. It is possible to launch the attack remotely. Additional levels of successful authentication are needed for exploitation. Technical details are known, but there is no available exploit. The structure of the vulnerability defines a possible price range of USD $0-$5k at the moment (estimation calculated on 08/05/2026). This vulnerability is assigned to T1505 by the MITRE ATT&CK project.
