Re: Microsoft Outlook Web Access (OWA) v8.2.254.0 "id" parameter Information Disclosure Vulnerability

[Jabłoński, Paweł <PJablonski () ivmx pl>]

Not working at my environment: Tested on Firefox 3.6.3 (Linux).

OWA version: 8.2.254.0

Exception type: Microsoft.Exchange.Data.Storage.CorruptDataException. OWA uses 
System.Convert.FromBase64String(String s) for parsing the address, so even when you 
try to put the representation there, you should get the invalid format of serialized ID anyways.
Weird it goes through at yours.
