Summary

Cacti from 1.2.27 before 1.2.31 has a stored SQL injection flaw (CWE-89) in its automation tree rule item handler. A user with Automation rights can save an SQL fragment that runs when an administrator applies automation rules. The attacker can use the query output to read database content in the tree UI. CISA's SSVC assessment lists proof-of-concept exploitation.

Description from the CNA

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.
