Web Application Footprints and Discovery

Web application assessment begins with IP address and ports (80/443) - this is very common practice. But there is flaw in this method. What if a web server is running with multiple virtual hosts? In other words, one server is running more than one web application.
In such a scenario, a web application assessment done on such IP/Port combinations may fail and produces partial results. Doing a reverse DNS on the IP and using it as HOST field in HTTP is an option, but may also fail most of the time.
So, where does the solution to this problem lie? The solution lies in the WHOIS information database and DNS server.
This paper describes how to fetch this information and follow up with the discovery process for web applications. |

This paper will provide a detailed analysis of the Buffer Overrun in JPEG Processing which started appearing on Microsoft software in September 2004.
Just a week prior to writing this paper, Microsoft announced a buffer overrun in JPEG processing in many of Microsoft’s software. This particular vulnerability increased the difficulty of patching for large organizations since it not only impacted operating systems, it also included many popular software packages such as Microsoft Office and development software such as Visual Studio .Net.
This paper will include an analysis of the timeline between the vendor announcement of this vulnerability, to actual exploit code or proof of concept, to an actual attack. An analysis of an attack as well as steps one could use to mitigate the risk of this vulnerability will also be completed. Finally, policies and processes that all organizations is included for reference.
I chose this particular vulnerability because of several reasons. The first was to understand the timeline users face when determining how long they have before they should patch. Often times, large organizations need to test patches against several different desktop builds, and that could take a couple days each. A second reason was to develop an understanding of this new type of attack. This particular attack focuses on user interaction, or even social engineering. Finally, there was little information available at the time this paper was being written. Therefore, it is my contribution to the community as an analysis of the new threat. |

Escalation of privileges is a common method of attack where a low privileged user exploits a vulnerability to become an administrator or a higher privileged user. Privilege escalation may be achieved through cracking of administrative passwords, local buffer overflows and stealing of passwords. This paper discusses a common vulnerability that could be exploited by low privileged users to steal critical passwords and escalate their privileges. |
