description

Cacti versions before 1.2.31 may be affected by a vulnerability corrected in that release. The available evidence does not establish the affected function, attacker impact, or conditions required for exploitation.

mitigation

Upgrade Cacti to version 1.2.31 or later. Follow the Cacti project's vendor guidance for any deployment-specific remediation steps.

no
automationDeterministic: a check that runs on its own, the same request on every target. Contextual: an agentic technique that needs to be applied per target, for bugs that depend on contextual flows.
deterministic
auth requiredWhether an attacker needs an account first, based on the CVSS vector's Privileges Required.
