CVE-2022-33175 is a critical-severity flaw (CVSS 9.8) affecting basic pdu firmware, pm pdu firmware, piml pdu firmware. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.
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.
