Multiple Mozilla products chrome: URI directory traversal

mozilla-chromeuri-directory-traversal (39840) The risk level is classified as MediumMedium Risk

Description:

Multiple Mozilla products with flat-packaged add-ons installed could allow a remote attacker to traverse directories on the system when the local file location is known. By persuading a victim to visit a malicious Web site embedded with a specially-crafted chrome: Uniform Resource Identifier (URI) containing encoded "dot dot" sequences (%2e%2e%2f), an attacker could exploit this vulnerability to view JavaScript, images or stylesheets, and obtain the contents of the sessionstore.js file.
