Authenticated object injection via unsanitized filter deserialization
Published Sep 5, 2023 · Updated Feb 13, 2025
Insecure deserialization in Cacti before 1.2.25 allows remote authenticated users to process crafted filter data as PHP objects. The host_new_graphs_save function in graphs_new.php deserializes selected_graphs_array, while form_actions in managers.php deserializes selected_items, without using Cacti's safe deserializer. Authentication is required, and the bundled phpseclib gadget chain lacks required files, so a vanilla installation has no demonstrated object-injection consequence.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
- Affected versionversion=0 <1.2.25
