Issues with passwords containing unescaped special chars

[Elix-g]

Dears,

latest WMI plugin installed in Cacti 1.2.5. Works smoothly except issues highlighted in another thread and when using passwords in a WMI query that contains a dollar character ($). Utilizing such password, regardless if stored in "WMI Queries | Authentication" or used in "WMI Query Tool", leads to an authentication failure against the given host. Executing exactly the same query with identical parameters from a command line (WMIC4.0.0TP4) runs smoothly so that the wmic binary can be excluded as root cause.

PHP: 7.2.19-0ubuntu0.18.04.1

Any help on this appreciated!

Thanks,
Elix
