Detailsinfo

A vulnerability was found in Powertek PDU. It has been rated as critical. This issue affects an unknown function of the file /cgi/get_param.cgi of the component Web Interface Handler. The manipulation of the argument tmpToken with an unknown input leads to a authorization vulnerability. Using CWE to declare the problem leads to CWE-639. The system's authorization functionality does not prevent one user from gaining access to another user's data or record by modifying the key value identifying the data. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

Power Distribution Units running on Powertek firmware (multiple brands) before 3.30.30 allows remote authorization bypass in the web interface. To exploit the vulnerability, an attacker must send an HTTP packet to the data retrieval interface (/cgi/get_param.cgi) with the tmpToken cookie set to an empty string followed by a semicolon. This bypasses an active session authorization check. This can be then used to fetch the values of protected sys.passwd and sys.su.name fields that contain the username and password in cleartext.

The weakness was released 06/14/2022. The advisory is shared at gynvael.coldwind.pl. The identification of this vulnerability is CVE-2022-33174 since 06/13/2022. Technical details are known, but no exploit is available.
