Mozilla-based browsers jar: URI cross-site scripting vulnerability
Mozilla-based web browsers including Firefox contain a vulnerability that may allow an attacker to execute code, or conduct cross-site scripting attacks.
The jar: protocol is designed to extract content from ZIP compressed files. Mozilla-based browsers include support for jar: URIs that are of the form jar:[url]![/path/to/file.ext]. The compressed file does not need to have a .zip extension.
From the GNUCITIZEN blog:
To successfully exploit this vulnerability, an attacker could place or link to a specially crafted archive file on a site and convince the user to open the file with a Mozilla based browser. An attacker could use sites that allow user-submitted content distribute malicious archived files.
This vulnerability may allow an attacker to execute cross-site scripting attacks on sites that allow users to upload pictures, archives, or other files.
