Introduction:  
-------------  
Swisscom CSIRT discovered a security flaw in the management interface  
of the Alcatel Lucent 1830 Photonic Service Switch series.  
  
  
Vulnerable:  
-----------  
All Switches of Release 6.0 or lower are vulnerable.  
  
  
Patches:  
--------  
None.  
  
  
Description:  
------------  
The management interface of the 1830 Photonic Switch series is vulnerable  
to reflected cross-site scripting, since user input is not properly encoded  
on output. Exploiting this vulnerability will lead to so-called cross-site  
scripting (XSS) and allows the impersonation of logged-in admin users.  
Additionally, the myurl-Parameter accepts non-local web addresses, which  
can be abused to redirect victims to arbitrary web sites.  
  
  
Attack vector:  
--------------  
https://xx.xx.xx.xx/menu/pop.html?myurl=);<script>alert('xss')</script>  
  
  
Statement Vendor:  
-----------------  
"The vulnerability is assessed at no risk. We will evaluate if/when we  
will add the best practice of validating all inputs in WebUI tasks, but  
this is not considered high priority for the roadmap."
