Vulnerability Details

This vulnerability allows remote attackers to execute arbitrary code on 
vulnerable installations of Oracle Business Intelligence One. Authentication 
is not required to exploit this vulnerability.

The flaw exists within the emagent.exe component which listens by default on 
TCP port 3938. When handling an HTTP request in oranmemso.dll the function 
nmehl_getURIParams blindly copies user supplied data into a fixed-length buffer 
on the stack. A remote attacker can exploit this vulnerability to execute 
arbitrary code under the context of the SYSTEM user.

Vendor Response
Oracle has issued an update to correct this vulnerability. More details can be
