Web administrators beware: Cross-site scripting vulnerabilities are now far more attractive targets than more notorious bugs such as buffer overflows, according to new figures from Mitre, a U.S. government-funded research organization.Buffer overflows have long been one of the most common types of bugs attacked by malware, with Intel and Advanced Micro Devices (AMD) even building in hardware support for an antibuffer overflow technology called No Execute (NX) or Execution Disable (XD).But a shift is under way, according to Mitre\u2019s findings. While buffer overflows affect executable files written in languages such as C, the increasing popularity of cross-site scripting (XSS) bugs indicates attackers are looking more at programming languages typically used for Web applications, such as Java, .Net and PHP.Client-side scripting languages generally include same-origin policies, which allow interaction between Web objects and pages only as long as they come from the same domain and over the same protocol. XSS bugs allow malicious websites to find ways around these policies, potentially accessing sensitive data in other objects or browser windows.The second most popular type of attack was SQL injection, which allows attackers to execute malicious SQL statements within a database. Third most popular were PHP "include" vulnerabilities, which can allow attackers to execute arbitrary script on a server by including them in an existing script.Out of about 20,000 reported vulnerabilities recorded by Mitre so far this year, 21.5 percent were XSS, 14 percent were SQL injection and 9.5 percent were PHP includes. Buffer overflows came in fourth, at 7.9 percent.Mitre first discussed the findings on Wednesday at the Cyber Security Executive Conference in New York, according to a report from industry journal Dark Reading.By Matthew Broersma, Techworld.comKeep checking in at our Security Feed for updated news coverage.
