Mozilla · Firefox · CVE-2016-2833
**Name of the Vulnerable Software and Affected Versions**
Mozilla Firefox versions prior to 47.0
**Description**
The issue exists due to the browser's failure to properly enforce web page structure protection, allowing a remote attacker to conduct cross-site scripting (XSS) attacks using a specially crafted applet. This can be achieved by ignoring Content Security Policy (CSP) directives for cross-domain Java applets.
**Recommendations**
For versions prior to 47.0, update to version 47.0 or later to resolve the issue. As a temporary workaround, consider disabling the use of Java applets in Mozilla Firefox until a patch is applied. Restrict access to potentially vulnerable web pages to minimize the risk of exploitation.
