Opera < 7.23 File Download Encoded Traversal Arbitrary File Deletion

medium Nessus Plugin ID 14246

Synopsis

Files could be overwritten on the remote host.

Description

The version of Opera installed on the remote host contains a file corruption vulnerability. This issue is exposed when a user is presented with a file dialog, which will cause the creation of a temporary file. It is possible to specify a relative path to another file on the system using directory traversal sequences when the download dialog is displayed. If the client user has write permissions to the attacker-specified file, it will be corrupted.

This could be exploited to delete sensitive files on the systems.

Solution

Install Opera 7.23 or newer.
