On the second Tuesday, what many now refer to as patch Tuesday , of April,
2004, Microsoft released four security bulletins. Among these was
Microsoft Security Bulletin MS04-011 which detailed fourteen separate
vulnerabilities, six of them rated critical for one or more Windows
operating systems. In the list of the vulnerability identifiers in the
Technical Details section of the bulletin is the PCT Vulnerability which
is also referenced as CAN-2003-07191 on the Common Vulnerabilities and
Exposures website. PCT is referred to variously within Security Bulletin
MS04-011 as the Private Communications Transport or Private Communication
Technology protocol. For the purposes of this paper David Schulhoff
selected this vulnerability and a corresponding exploit to examine in
detail. We will take a look at both what makes this vulnerability a
classic opportunity for exploitation and how its unique characteristics
provide an insight into some basic security principles. David Schulhoff
takes the approach of an individual seeking to take advantage of this
opportunity , and then look at two different scenarios of organizations
dealing with an incident caused by an attack on the PCT vulnerability.
