Novell ZENworks Patch Management 6.3 - ZPM6.3 Server Web Interface
A certain combination of changes made to the selection criteria on the Vulnerabilities screen results in an internal server error.
On a screen that shows vulnerabilities (either the main screen, or one for an individual device) change the status drop-down, then immediately change the "show results on Page Load:" box (either check or uncheck), and an internal server error will be displayed.
This is fixed in version 6.4
As a workaround, ensure a refresh is performed between each change.
