[+] Vulnerabilities  
  
Stored Cross-site Scripting:  
Web interface from PA101, PU201, PA301 and PS531 Print Servers are affected by stored  
cross-site scripting vulnerability because it fails to properly sanitize  
user-supplied input at "NDSContext" field in "NetWare NDS Settings" area.  
An attacker may leverage this issue to execute arbitrary script code  
in the browser of an unsuspecting user in the context of the affected site.  
  
After injecting the XSS code, you need to access Netware status page.
