Common Software Vulnerabilities

Most cyber-attacks happen because vulnerabilities in system or application software. Buffer Overflow, SQL Injection, Code/OS Command Injection, Cross-Site Scripting (XSS), Cross-Site Request Forgery and Race Conditions are very common vulnerabilities. (Refer to both NIST/DHS and MITRE databases of common vulnerabilities (http://nvd.nist.gov/cwe.cfm; http://cwe.mitre.org/top25/).) For this conference, explain what a specific vulnerability is, describe a famous attack that leveraged it (For example, the Morris worm leveraged the buffer overflow vulnerability), and how it can be prevented/minimized. Your post can either discuss a vulnerability that has not been discussed, or expand upon what someone has already posted. I encourage multiple postings by an individual. Try not to repeat what is already posted.
