Who is Vulnerable?
Vulnerability Description The Unisys Business Information Server is a business information management solution that provides data access, analysis and reporting in an open, enterprise-wide computing environment. Business Information Server transforms corporate data into information that is made available throughout the enterprise. A stack-based buffer overflow vulnerability exists in Unisys Business Information Server that could allow remote attackers to execute arbitrary code on a vulnerable system. The flaw is due to a boundary error when processing crafted packets sent to the server. Remote attackers could exploit this vulnerability by sending a crafted packet to a TCP port. In an attack case where code injection is not successful, the affected service will terminate resulting in a Denial of Service condition. In a more sophisticated attack where code injection is successful, the behavior of the target is entirely dependent on the
intended function of the injected code. The injected code in such a case would execute within the security context of the service, which is SYSTEM by default.
