Summary
InfraPower Manager PPS-02-S is a FREE built-in GUI of each IP dongle ( IPD-02-S only ) to remotely monitor the connected PDUs. Patented IP Dongle provides IP remote access to the PDUs by a true network IP address chain. Only 1xIP dongle allows access to max. 16 PDUs in daisy chain - which is a highly efficient cient application for saving not only the IP remote accessories cost, but also the true IP addresses required on the PDU management.Description
InfraPower suffers from multiple unauthenticated remote command injection vulnerabilities. The vulnerability exist due to several POST parameters in several scripts not being sanitized when using the exec(), proc_open(), popen() and shell_exec() PHP function while updating the settings on the affected device. This allows the attacker to execute arbitrary system commands as the root user and bypass access controls in place.Vendor
