CVE-2022-33175 — Powertekpdus Basic Pdu Firmware security vulnerability

Critical CVSS 9.8

Power Distribution Units running on Powertek firmware (multiple brands) before 3.30.30 have an insecure permissions setting on the user.token field that is accessible to everyone through the /cgi/get_param.cgi HTTP API. This leads to disclosing active session ids of currently logged-in administrators. The session id can then be reused to act as the administrator, allowing reading of the cleartext password, or reconfiguring the device.

Privilege escalation and unsafe privilege management

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Map service accounts, operating-system identities, roles, capabilities, impersonation, set-user transitions, and administrative helper paths.
  • Determine whether untrusted users or lower-privilege processes can reach the affected transition or modify inputs it trusts.
  • Review file, socket, registry, device, job, container, and cloud-role permissions used before and after privilege changes.

Remediate safely

  • Apply the supported fix and redesign privileged operations as a minimal, authenticated, allowlisted interface.
  • Drop privileges before processing untrusted input, verify the drop succeeds, and remove unnecessary roles, capabilities, and write permissions.
  • Validate ownership and permissions at time of use and add explicit lower-to-higher privilege boundary tests.
