cacti: Cacti is an open source performance and fault management framework
CVE-2025-66399 is fixed in cacti on 1 platform, first by DEBIAN-CVE-2025-66399, released December 2, 2025. It is not reported as exploited. Patch Radar priority: High.
Cacti is an open source performance and fault management framework. Prior to 1.2.29, there is an input-validation flaw in the SNMP device configuration functionality. An authenticated Cacti user can supply crafted SNMP community strings containing control characters (including newlines) that are accepted, stored verbatim in the database, and later embedded into backend SNMP operations. In environments where downstream SNMP tooling or wrappers interpret newline-separated tokens as command boundaries, this can lead to unintended command execution with the privileges of the Cacti process. This vulnerability is fixed in 1.2.29.
