Tuesday, November 10, 2009, 10:15am - Tuesday, November 10, 2009, 11:30am

ITE 325 - B

web application security

In this week's Ebiquity Lab meeting Vivek Relan[1] from the Cyber Defense Lab[2] at UMBC will talk about "Web Application Session Attacks - Cause, Effect and Remediation"


An increase in the usage of Web application is directly related to an increase in number of security incidents for them. Most of the Web sites have vulnerabilities that could lead to the theft of sensitive corporate data such as credit card information and customer's list. These threats originate because of either unconventional development of Web application or careless handling of Web sessions or flawed deployment of Web servers.

This talk will focus on a class of session vulnerabilities in Web application, their cause, effect and how to avoid them. Three session attacks - Session fixation[3], Cross-Site Request Forgery (CSRF/XSRF) [4] and Privilege Escalation[5] will be discussed along with their demonstration. In addition, Vivek will also talk about his published security advisory on Yahoo! Mail XSS vulnerability[6].
