VncRecorder Plugin 1.25 and earlier does not escape a tool path in the checkVncServ form validation endpoint accessed e.g. via job configuration forms.

This results in a stored cross-site scripting (XSS) vulnerability exploitable by Jenkins administrators.

VncRecorder Plugin 1.35 escapes the tool path.
