TippingPoint™ IPS Customer ProtectionTippingPoint IPS customers are protected against this vulnerability by Digital Vaccine protection filter ID 11697. For further product information on the TippingPoint IPS:
This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of HP Managed Printing Administration. Authentication is not required to exploit this vulnerability.
The specific flaw exists within the MPAUploader.dll file. An extended length string can be passed into scripts within the management website on port 80 (the 'uploadfile' multipart form data 'filename' parameter in Default.asp) and ultimately to MPAUploader.dll. As a static stack allocation is used to store the buffer and the string length is not handled properly, a remote attacker may overwrite the stack and ultimately execute remote code.
