CVE-2016-2833: Mozilla Firefox before 47.0 ignores Content Security Policy (CSP) directives for cross-domain Java applets,...

Mozilla Firefox before 47.0 ignores Content Security Policy (CSP) directives for cross-domain Java applets, which makes it easier for remote attackers to conduct cross-site scripting (XSS) attacks via a crafted applet.

Security readout for executives and security teams

Older Firefox versions could fail to enforce a website’s Content Security Policy around cross-domain Java applets. That weakens a browser-side defense and could make cross-site scripting easier if a user visits a malicious or compromised page. Exposure is most likely on legacy endpoints running Mozilla Firefox earlier than 47.0, especially where Java applets remain usable. Modern maintained Firefox installations should not be exposed to this specific fixed issue. Treat this as a legacy browser hygiene issue, not an emergency, unless unsupported Firefox or Java applets remain in use. Prioritize cleanup in regulated, shared, or high-risk user environments. Mitigation focus: Upgrade Mozilla Firefox to 47.0 or later per Mozilla guidance.; Apply Ubuntu or openSUSE Firefox updates where those distributions manage packages.; Identify and retire any remaining Firefox versions earlier than 47.0..
