Cross-application scripting

Cross-application scripting (CAS) is a vulnerability affecting desktop applications that don't check input in an exhaustive way. CAS allows an attacker to insert data that modifies the behaviour of a particular desktop application. This makes it possible to extract data from inside of the users' systems. Attackers may gain the full privileges of the attacked application when exploiting CAS vulnerabilities; the attack is to some degree independent of the underlying operating system and hardware architecture.
