Cross-site scripting and SQL injection are the 1-2 punch of security weaknesses in 2010. Even when a software package doesn't primarily run on the web, there's a good chance that it has a web-based management interface or HTML-based output formats that allow cross-site scripting. For data-rich software applications, SQL injection is the means to steal the keys to the kingdom. The classic buffer overflow comes in third, while more complex buffer overflow variants are sprinkled in the rest of the Top 25.
