Abstract: Most internet applications are providing facilities through the web services. Due to its wide usage, these web services are exposed to severe vulnerabilities that can be uncovered and exploited by hackers. In these vulnerabilities, command injection is the most frequent type of attack that can take advantage of improperly designed applications. These attacks inject and execute commands specified by the attacker, allowing unauthorised access to database schema and critical data stored in data logic. In this paper, a new approach is proposed to effectively detect the command injection vulnerabilities such as SQL injection attacks, by validating the dynamically generated query that is to be executed in the database server. This approach involves Aspect Oriented Programming (AOP) technique, which is used for separating cross cutting concerns such as security from applications. The approach is effective since it uses a XML schema instead of existing methods for validation.

Keywords: SQL injection attacks; web application security; XML schema; web services; tautology; piggyback; parse tree; aspect oriented programming; command injection attacks; command injection vulnerabilities.
