CVE-2021-40995Network attack vector

Authenticated command execution through CLI injection

Published Oct 15, 2021 · Updated Aug 4, 2024

Command injection in affected ClearPass Policy Manager 6.8.x, 6.9.x, and 6.10.x releases allows remote authenticated users to execute host commands. HPE identifies the command-line interface as the affected locus but has not disclosed the command, parameter, or input-handling path. Reachability requires a low-privilege authenticated account with CLI access; execution can read, modify, or interrupt data and services within that account's context.
