Description

The Fizzle add-on for Mozilla Firefox contains a flaw that allows a remote cross site scripting attack. This flaw exists because the application does not validate RSS feed data upon converting HTML entity code back into ASCII equivalents. This could allow a user to create a specially crafted feed that would execute untrusted code in a user's browser within a trusted context of the browser, leading to a loss of integrity.

Classification

Location: Remote / Network Access
Attack Type: Input Manipulation
Impact: Loss of Integrity
Exploit: Exploit Public
OSVDB: Web Related

Solution

Currently, there are no known upgrades or patches to correct this issue. It is possible to correct the flaw by implementing the following workaround(s):
- Do not subscribe to untrusted XML feeds
- Disallow HTML within an XML feed if the option is present.
