# Cacti: stored SQL injection through automation tree rules, fixed in 1.2.31

Cacti versions 1.2.27 up to 1.2.31 let a user with the Automation permission store a SQL fragment in an automation tree rule that is later run unsanitized against the database. The injected query output is written into the Cacti tree UI, which gives the attacker a way to read data from the database.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Check the installed Cacti version in the web UI footer or in `include/global.php` (look for `$config['cacti_version']`).
- In the Cacti UI, review Automation tree rules for unexpected entries if you suspect misuse.

## Fix

- Upgrade Cacti to `1.2.31` or later.
- Until upgraded, restrict the Automation realm to trusted users only.

## From the sources

Cacti is an open source performance and fault management framework. From version 1.2.27 to before version 1.2.31, Cacti contains an authenticated stored second-order SQL injection in the automation tree rule item handler. A user holding the Automation realm (default General Administration role) can persist an arbitrary SQL fragment in the automation_tree_rule_items.field column. The fragment is later concatenated directly into a SELECT ... AS source FROM ... clause in lib/api_automation.php :: create_all_header_nodes() and executed when an administrator triggers automation via the standard graphs.php?action=actions&drp_action=8 ("Apply Automation Rules") bulk action. The result of the injected SELECT is written into graph_tree_items.title and rendered in the Cacti tree UI, providing a direct exfiltration channe. This issue has been patched in version 1.2.31.
