CVE-2023-24493Network attack vector

Host formula execution via unsanitized report exports

Published Jan 25, 2023 · Updated Apr 1, 2025

Formula injection in Tenable Security Center 5.23.1 and earlier allows remote authenticated users to execute formulas via exported reports. The reporting system preserves user-supplied formulas in exported report fields instead of neutralizing them as data. Successful exploitation requires a victim to approve and execute the exported formula on a host.
