Improper Control of Generation of Code ('Code Injection')
The browser-plugin implementation in RealNetworks RealPlayer 11.0 through 11.1 and RealPlayer SP 1.0 through 1.1 allows remote attackers to arguments to the RecordClip method, which allows remote attackers to download an arbitrary program onto a client machine, and execute this program, via a " (double quote) in an argument to the RecordClip method, aka "parameter injection."
CWE-94 - Code Injection
Code injection is a type of vulnerability that allows an attacker to execute arbitrary code. This vulnerability fully compromises the machine and can cause a wide variety of security issues, such as unauthorized access to sensitive information, manipulation of data, denial of service attacks etc. Code injection is different from command injection in the fact that it is limited by the functionality of the injected language (e.g. PHP), as opposed to command injection, which leverages existing code to execute commands, usually within the context of a shell.
