Quick Look Apple Mac OS X 10.5.1, when previewing an HTML file, does not prevent plug-ins from making network requests, which might allow remote attackers to obtain sensitive information.


This leverage executable code vulnerability has been classified with a high base score of 9.4, a high impact score of 9.2 and a high exploitability score of 10.

Economic Impact

The economic impact provides a custom overview of the affected areas by this vulnerability. If there is a higher amount of predicted attacks, there is a higher probability to be affected by this vulnerability in this particular region.


Common Attack Pattern Enumeration and Classification (CAPEC) is a comprehensive dictionary and classification taxonomy of known attacks that can be used by analysts, developers, testers, and educators to deepen community understanding and enhance protection. The vulnerability has been classificated in 8 categories.

Manipulating Web Input to File System Calls

An attacker manipulates inputs to the target software which the target software passes to file system calls in the OS. The goal is to gain access to, and perhaps modify, areas of the file system that the target software did not intend to be accessible.

Leverage Executable Code in Non-Executable Files

An attack of this type exploits a system's trust in configuration and resource files. When the executable loads the resource (such as an image file or configuration file) the attacker has modified the file to either execute malicious code directly or manipulate the target process (e.g

Using Malicious Files

An attack of this type exploits a system's configuration that allows an attacker to either directly access an executable file, for example through shell access; or in a possible worst case allows an attacker to upload a file and then execute it. Web servers, ftp servers, and message oriented middleware systems which have many integration points are particularly vulnerable, because both the programmers and the administrators must be in synch regarding the interfaces and the correct privileges for each interface.

Target Programs with Elevated Privileges

This attack targets programs running with elevated privileges. The attacker would try to leverage a bug in the running program and get arbitrary code to execute with elevated privileges

Restful Privilege Elevation

Rest uses standard HTTP (Get, Put, Delete) style permissions methods, but these are not necessarily correlated generally with back end programs. Strict interpretation of HTTP get methods means that these HTTP Get services should not be used to delete information on the server, but there is no access control mechanism to back up this logic


CPE is a structured naming scheme for information technology systems, software, and packages. Based on a common Uniform Resource Identifier (URI) syntax, CPE includes a formal naming format, a method for validating system names, and a description format for attaching text and tests to the name.
