CVE-2010-3749

La implementación del complemento del navegador de RealNetworks RealPlayer v11.0 hasta la v11.1 y RealPlayer SP 1.0 hasta la v1.1 no maneja apropiadamente un caracter sin especificar dentro de los argumentos del método RecordClip; lo que permite a atacantes remotos descargar programas de su elección en el ordenador cliente, y ejecutar estos programas, a través de una llamada a método modificada. Relacionado con un problema de inyección de parámetros.

This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of RealNetworks RealPlayer. User interaction is required to exploit this vulnerability in that the target must visit a malicious page.
The specific flaw exists within the browser plugins provided by RealNetworks. The RecordClip method can be access via the ActiveX control or the Firefox plugin. By injecting a specific character into the arguments to this method, invalid parameters can be passed to a child process that is launched on the local system. This parameter injection allows an attacker to download and subsequently execute a file on a target system, thus allowing for remote code execution.
